Syphon Filter is a third-person stealth-action shooter for the PlayStation released in 1999. It is the first game in the Syphon Filter franchise.
The playable game takes place between August 23 and September 8, 1999 and follows the efforts of operative Gabe Logan, and his partner Lian Xing, to stop a series of bioweapon attacks initiated by international terrorist Erich Rhoemer and his organization, Black Baton, who are in possession of a powerful virus known as Syphon Filter.
In August 1999, Gabriel "Gabe" Logan and Lian Xing, agents of a secretive U.S. government organzation known as The Agency, are investigating a series of viral outbreaks caused by an unknown pathogen. They infiltrate a plantation in Guacimo, Costa Rica after losing contact with a fellow agent, Ellis, who was investigating a potential terrorist threat in the area. Ellis is being held prisoner by international terrorist Erich Rhoemer and his Black Baton squad, who are preparing to leave and destroy all evidence of their activities. Rhoemer orders Anton Girdeux to burn everything using his flamethrower and Mara Aramov to execute Ellis, who has been exposed as an informant. As Gabe and Lian approach the coordinates they were sent, they hear multiple gunshots ring out. They arrive on scene to find Ellis dead, the terrorists gone, and the area set ablaze. Gabe realizes that Rhoemer knew that they were coming. Without any evidence, he tells Lian that they will need to wait for the next viral outbreak.
At Agency headquarters in Washington, D.C. Agency director Thomas Markinson discusses the Agency's next moves. Markinson orders Deputy Director Edward Benton to put together additional teams to find Rhoemer. He then asks for guidance from an unidentified man, who tells Markinson to wait and see what Logan discovers.
Some time later, Gabe and Lian are sent to investiage a viral outbreak in Khumbu, Nepal. Gabe confirms a WHO report that the pathogen has killed everyone within 100 miles of the village. However, Lian discovers that one person is still alive. Gabe asks how this is possible - Lian replies that is is not.
Washington D.C. Attack
On August 23, Rhoemer launches an attack on Washington, D.C. with viral bombs containing the same virus that Gabe and Lian have been investigating. Gabe is sent in to help the U.S. Army Chemical and Biological Defense Command (CBDC) contain the viral threat as well as intercept and eliminate Rhoemer and his accomplices. He eliminates Pavel Kravitch, Rhoemer's communications expert and rescues several CBDC agents from an ambush before pursuing the terrorists into the Georgia Street subway station. Gabe finds and tags two viral bombs on the upper level of the station and finds another on the lower level, As he attempts to tag the final device, he realizes that it is not a viral device, but an explosive planted to cover Rhoemer's escape. As the timer is nearing zero, Gabe quickly attempts to take cover from the bomb, which explodes. Several other explosions tear through the station, destroying it and a number of subway cars that were passing through.
Gabe survives the explosion but finds himself trapped in the lower level of the station. Lian informs him that Rhoemer was last seen on the upper level making his way towards the main subway tunnel. Gabe manages to climb his way to the upper level and uses C4 explosives to blast away debris from the entry ramps so that CBDC can come in and disarm the tagged viral bombs. Gabe then shuts off a ruptured gas main and makes his way towards the main subway line, where he has his first encounter with Mara Aramov. Gabe pursues Aramov through the tunnel, dodging trains that are shuttling in emergency personnel. He is able to wound her, but is unable to gain any useful information from her before she falls unconscious.
Gabe leaves Aramov in the subway tunnel and makes his way towards Washington Park, where he believes the main viral bomb to be located with Girdeux. Lian had previously informed Gabe that a team headed by Jenkins had been sent to the park but was under heavy fire, possibly due to an Agency leak. As Gabe enters the park, Benton informs him that Jenkins' team was killed and that he is having Gabe continue their mission of assisting CBDC. Gabe is able to help CBDC agents disarm several viral bombs planted in the park, then resumes his original mission. Gabe eliminates Rhoemer's trigger man, Jorge Marcos, then makes his way to the Freedom Memorial at the northern end of the park. Inside, he finds the main viral bomb along with Girdeux, who is in full body armor and armed with his flamethrower. Girdeux criticizes the United States' history of wars and aggression as depicted in the memorial, and claims that the terrorists are about to make an addition to it, but Gabe dimisses him. Unable to engage Girdeux in a conventional manner, Gabe instead targets the exposed fuel tank on Girdeux's back while dodging his flamethrower attacks. After hitting the tank several times, it eventually ruptures and bursts into flames, burning Girdeux to death in his armor. The terrorist threat eliminated, Gabe calls for CDBC to disarm the final device.
New York City: PHARCOM Exposition Center
The next day, Lian informs Gabe and Markinson that compounds taken from the blood of Rhoemer's terrorists matches those found during the mission to Costa Rica, and were patented by Pharcom, an international pharmaceutical corporation based in New York City and headed by Jonathan Phagan. Gabe surmises that the organization may be funding Rhoemer's operations, but Markinson replies that Pharcom was previously investigated by Benton. However, Gabe casts suspicion on Benton following the botched missions in Costa Rica and Washington Park. Markinson has placed Benton on leave, but agrees that there may be a connection between Phagan and Rhoemer. Gabe is sent to a reception at the Pharcom Exposition Center to investigate.
When Phagan leaves the reception, Gabe silently tails him until he arrives in an exhibit and finds Aramov and Benton waiting for him. Gabe confirms with Lian that Benton was the source of the Agency's leak. Benton informs Phagan that plans have changed and Aramov holds him at gunpoint, demanding the location of the Syphon Filter labs. However, when Benton discovers that Phagan has a wire, Phagan makes a run for it, with Aramov in pursuit. Benton stays behind and attempts to fight, but Gabe kills him, blowing his cover in the process. Gabe fights his way through the building to the security room, where Lian discovers that Aramov is interrogating Phagan at gunpoint in the dinosaur exhibit. Gabe knows that he needs both alive, since Phagan knows where the virus is being manufactured and Aramov has the location of Rhoemer's base. Gabe fights his way to the dinosaur exhibit and incapacitates Aramov, allowing Phagan to escape unharmed.
Kazakhstan: Rhoemer's Base
One week after the Expo Center operation, Gabe informs Markinson that Benton was acting as a double agent, but Markinson reveals that he has known this for some time and chose not to disclose this knowledge to Gabe and Lian. In the meantime, Phagan has disappeared and the Agency has not yet determined the location of the virus labs from Pharcom's encrypted data. Markinson informs Gabe that Rhoemer's base has been found in Kazakhstan and that Gabe is being sent in to catalog a series of ballistic missiles before destroying the base.
Gabe is dropped outside the base's perimeter and gains access underneath a supply truck. He then works his way towards the missile bunker, planting C4 charges on fuel tanks and shutting down the bunker's motion sensing security system as well as eliminating Rhoemer's chief of security, Vadislav Gabrek. Upon entering the bunker, the base goes on alert, but Gabe is able to continue his mission and catalog a series of SS-23 ballistic missiles. He then makes his way to the roof to disable the base's anti-aircraft radar. Lian informs Gabe that she has been discovered and is coming under fire. When Gabe shuts the radar down, Lian attempts to pick him up but is captured and killed by Rhoemer, as Gabe can do nothing but listen. Rhoemer sends an attack helicopter to take Gabe out, but Gabe is able to destroy it. As he gets off the roof, Gabe triggers the timer on his C4 explosives and informs Markinson that Lian has been killed. Markinson tells Gabe that he will need to fight his way back to the front gate, where a backup chopper will pick him up. Gabe is barely able to escape the base before it is destroyed.
Ukraine: Rhoemer's Stronghold
Six days after escaping from Rhoemer's base, Gabe is given a report on the Syphon Filter virus by Markinson, which reveals its capability to kill massive populations of people, who have been "programmed" for termination, but leave certain individuals completely unharmed. Markinson tells Gabe that the Agency has found and destroyed the Pharcom labs that were producing the virus, but that only Phagan knows the location of the computers where the DNA sequencing occurs. Aramov has escaped and there is still no sign of Rhoemer, but Phagan was captured and is being held at a cathedral in Ukraine where Rhoemer keeps prisoners to be used as viral test subjects. Gabe tells Markinson that he doesn't want a replacement for Lian and Markinson tells him that he isn't getting one.
Markinson drops Gabe off on the roof of the cathedral, instructing Gabe to inject any test subjects he finds with a vaccine that the Agency labs developed, and to kill any of Rhoemer's medical personnel on site. Gabe begins making his way downward, administering the vaccine to test subjects and eliminating Rhoemer's guards and scientists. He comments on the abundance of Pharcom and WHO shipping containers as an indication of a big plan, but Markinson tells Gabe not to get distracted.
When Gabe reaches the underground catacombs, he overhears that Rhoemer has ordered the execution of the prisoners. Markinson tells Gabe that he needs to allow one of the guards to use the palm print security system to open Phagan's cell. Gabe silently tails the guard through the catacombs until he reaches the cell. The guard opens the cell and prepares to give Phagan an injection. Phagan begs for his life before Gabe shoots the guard. Gabe demands the location of the sequencing computers from Phagan at gunpoint. Phagan tells Gabe the computers are in an abandoned silo in Kazahkstan underneath a warehouse district, which Gabe relays to Markinson. Markinson tells Gabe to take Phagan with him to the designated evac point.
Phagan tells Gabe that Lian is alive and offers to take Gabe to her cell if he allows Phagan to go free. Gabe doesn't believe Phagan and tells him to prove it. Gabe covers Phagan as he shows him the way to Lian's cell. Phagan opens the cell, then runs. Gabe is shocked, but relieved to find that Lian is alive. He tells Lian that the Agency has the location of the sequencing computers and that Markinson is on the way to pick them up. Lian tells Gabe that she has been infected with Syphon Filter. Gabe tries to reassure her that the Agency has a vaccine, but Lian tells him that there is no universal vaccine as the specific lock and key for each programmed virus is required from the sequencing computers, and that they need to get there before the Agency destroys everything. Gabe also realizes that Markinson lied to him about the vaccine. Lian tells Gabe to follow her as she knows the way out. As they reach the exit, they catch up with Phagan, who is shot in the head by Aramov. Aramov tells Gabe and Lian that Rhoemer needs to be stopped or they will all die, and that she has a chopper to use to take them to Kazakhstan. Phagan is left for dead.
Kazakhstan: Pharcom Warehouse District
Gabe, Lian and Aramov arrive at the Pharcom warehouses to find that Rhoemer has also discovered their location, as his men are attacking in force, resulting in a large-scale firefight with Phagan's security forces. Aramov tells Gabe that the mainframe computer can only be accessed via mining tunnels located underneath Warehouse 76. Gabe tells Lian to try and contact Markinson, who has gone dark since they left Ukraine. Using the firefight to avoid attracting attention, Gabe first obtains the access codes to the silo computers from Richard Erickson, as well as a viral scanner to detect stored viral carriers which Gabe must tag for proper disposal. Gabe makes his way through the warehouses, tagging the viral carriers, and makes his way towards the southern end of the complex using a series of underground tunnels. He comes across shipping manifests for the R-9 Devyatka, a retired ballistic rocket that Gabe suspects may be part of Rhoemer and Phagan's plans for Syphon Filter. Lian tells Gabe that she is still unable to contact Markinson. Gabe continues through the southern section of the complex, which is guarded by Phagan's elite guards. Gabe tags additional viral carriers and then locates Warehouse 76, only accessible through another series of underground passages.
When he reaches the entrance to Warehouse 76, he is attacked by several grenadiers. Their grenades destroy a series of fuel tanks outside the entrance and start a massive fire that engulfs the entire warehouse district. Lian confirms that the serum Gabe was given to inject the test subjects in Ukraine with contained concetrated potassium chloride used in lethal injections, meaning that Markinson was knowingly having Gabe kill the test subjects. With no other options, Gabe runs into the burning warehouse and begins searching for the elevator to the mining caves. As he makes his way through, his progress is hampered by Pharcom guards and the warehouse falling apart around him. After a few minutes, Gabe is able to locate the elevator in the rear of the warehouse and begins descending into the mining caves. The elevator falls the last few feet into the cave as Warehouse 76 collapses above.
Gabe emerges into the mining cave and immediately finds himself engaged with several of Rhoemer's men. He kills them but finds his progress stopped by security lasers. Aramov says that the only way to disable them is to cut the power to the entire tunnel system. To reach the power room, Gabe must first reactivate a series of elevators that were disabled when the warehouse fires broke out. When he reaches the power room, he doesn't find a way to shut the power off and instead tries to overload the generators, triggering a massive explosion. Gabe survives the explosion and makes his way out of the destroyed power room. Using the resulting blackout to his advantage, Gabe is able to make his way past Rhoemer's guards to the silo entrance.
Upon entering the silo, Gabe finds the Devyatka missile ready for launch. He tells Lian that the launch countdown is in progress but that the codes he obtained from Erickson won't give him access to the launch computer. Lian tells Gabe he won't be able to prevent the launch, but that they can destroy the missile mid-flight if Gabe can get the self-destruct codes from the fuselage before launch. Gabe makes his way down to the lower level, then climbs the missile and retrieves the codes. When he drops back to the ground, he finds Markinson standing before him. Markinson admits that he knew Gabe would discover his involvement with Syphon Filter and asks where Rhoemer is. Realizing Markinson's deception, Gabe responds by asking how long Rhoemer has been working for him. Markinson explains that after the mission in Costa Rica, Markinson did research of his own and decided that he wanted to procure the virus for the Agency. When Gabe asks about the missile, Rhoemer appears and shoots Markinson dead, then tells Gabe that the missile was his idea and that Markinson had come to stop the launch. Gabe asks who the target is, but Rhoemer says it doesn't matter. Gabe is forced to take cover as the missile launches, then makes his way to the command computer. Lian tells Gabe that he needs to destroy the missile or a global war will likely result. Gabe reaches the mainframe and is able to trigger the missile's detonation with seconds to spare, and begins downloading the Syphon Filter DNA sequencing data. An enraged Rhoemer enters the mainframe room clad in full armor and confronts Gabe with an M-79. Gabe engages him in a final battle, in which he finds a crate of nerve gas grenades. Gabe throws the grenades at Rhoemer, who collapses and falls dead in the ensuing cloud of poison.
Gabe meets up with Lian and Aramov is taken into custody by Agency operatives as CDBC arrives to contain the scene. Lian asks Gabe what will happen now that Rhoemer and Phagan are dead and what their involvement with Markinson and Syphon Filter really means. Gabe replies that with Markinson dead, they may never know the full story.

Interview: Behind the Classics
PlayStation.Blog: What was the original base concept for the game? Was it in any way a response to Metal Gear Solid, or did the idea develop in a relative vacuum?
John Garvin, Creative Director at Bend Studio: Metal Gear Solid actually had nothing to do with the genesis of Syphon Filter. We had been in development for quite a while before we had even heard of it. The idea originally came from a producer at Sony’s (then) 989 Studios who had written a one page synopsis that he called “Syphon Filter” which had zero meaning, i.e. there was no plot, no character, and no story, just an idea for settings, mechanics and gameplay. From the beginning it was to be a “stealth action” game (in the days before there was such a genre) that focused heavily on weapons, gadgets and stealth. Our goal was to make the player feel like a super spy. Our lead designer back then was pretty heavily influenced by Nintendo’s GoldenEye, which was probably the closest you could come to finding a game like Syphon in those days.
PSB: Did you know you were working on something special? What were your creative conditions as you worked on it – uncertainty, confidence, terror?
JG: Mostly terror. It was a hard project in terms of development, for a lot of reasons. There were no, or few, games that we could draw on for inspiration. Most of the team had zero experience making this kind of game: The guys at Eidetic had just made Bubsy 3D, so they had some experience with doing a third-person action game, but Bubsy was a cartoon platformer so it wasn’t much help; I was brought on after the first Syphon Filter prototype was underway (a simple shooting segment in a subway), but my experience to that point was directing strategy games like MissionForce: Cyberstorm and art directing games like Sega CD’s Bouncers. None of us knew anything about making realistic shooters set in a spy world.
The first Syphon Filter went through a few rough patches and came close to being canceled several times as we missed deadlines, revamped mechanics, swapped levels around, changed the story, and generally tried to figure out what the heck we were doing. Our producer at 989, Connie Booth, and her boss Kelly Flock, were great though showing great faith in this new “spy genre” game. Our team ended up working in crunch mode for about a year as we tried to get the game up to everyone’s standards.
We didn’t know we had something special until after we shipped and sales took off like crazy, surpassing everyone’s expectations. I think we sold over a million units that first year. It was amazing. Players seemed to really appreciate doing something new — sneaking around, fighting terrorists while dodging subway cars, shooting a taser halfway down a city block and making a terrorist burst into flame. Things players had never before experienced. This kind of thing may be common now, but back then it was still all pretty new.
PSB: Did you draw inspiration from anywhere in particular for the game’s look and feel?
JG: Mostly my own experience. A lot of games these days are going for a dark, gritty, monochromatic look, but the games I remember playing in the late 1990s were all pretty colorful and weren’t all that realistic. Look at screens from Unreal, Turok 2, or Rainbow Six, which were realistic but had a palette that seemed all over the place. I remember being really inspired by Saving Private Ryan – which came out in 1998 I think – and Half Life.
PSB: It was an ambitious title for its time. What were the biggest challenges in realizing your original vision?
JG: It wasn’t really about realizing our original vision, because we were making it up as we went. We knew we wanted a third-person action game, and we knew we wanted to deliver on the fantasy of being a super spy. For us that meant even if something was “janky,” we’d do it if it could help sell the fantasy. For example, our rendered movies were pretty low budget. We didn’t even have articulated fingers. All our characters had “box” hands, but that didn’t stop us from having rendered movies because we had a story we wanted to tell. Our motto was that “bad movies are better than no movies.” Same thing went for game play sequences. We had a set-up where Gabe, the super spy star of the game, had to wear a tuxedo and infiltrate a black-tie event to spy on someone. Today that whole sequence would be very expensive, requiring sets, extras, costumes, and lots of mocap and animation; back then we just palette swapped some of our NPCs and did some very low budget animation of them standing around drinking cocktails. Once the game started, the player could hear a looping sound of the party, but couldn’t actually go back to the room where the party was being held. This kind of thing probably wouldn’t fly today, but we did all sorts of shortcuts back then to increase the scope of the experience without worrying about how polished it was. It was all about the game.
PSB: How close to your original concept was the finished game?
JG: Syphon Filter just wasn’t developed that way. The original concept of the player becoming a super spy was adhered to pretty closely, but everything else was worked out as we developed. A crazy way to make a game, but a process we made work because our team was only about 13 people. Here’s some examples: the story for Syphon Filter when I was brought on board was all about a group of scientists who had been kidnapped and taken to a huge underground complex where they were being forced to build a time machine by an evil scientist / government. I was hired to be the art director, but I began to offer ways to improve the story to make it more current, more relevant (I had been the art director, writer and designer on my projects at Dynamix, my previous game company). The studio directors liked my ideas and midway through development I rewrote the entire thing, coming up with the idea that the phrase “Syphon Filter” actually was a code word for a deadly “programmable” virus. None of that stuff was new, science fiction and film had explored ideas like these for years, but it was new to games.
We were shuffling levels around as late as weeks before we shipped in order to help pacing and flow issues. We changed locations and concepts mid-stream: the Girdeux boss fight was originally going to happen in a parking lot near the par, but I remember thinking at the time how hard it was going to be to build all those cars, and the challenge of “fencing” the player’s movement in an open space like a parking lot…and, could our engine even pull it off? So I went home over the weekend and built the “memorial” room, including downloading and chopping up that huge mural that ringed the wall of the space. It was a pretty big hit and was something we could pull off.
It really wasn’t until the sequel that we had a vision for the game. The entire team was given a week off and the game’s co-creator, Richard Ham, and I were sent off to write up a script for Syphon Filter 2. I think I spent a weekend and wrote the entire screenplay. Rich and I got together and he helped revise the second half of the game, introducing all the Moscow stuff, making the end of the story more espionage-like and exciting. When the team came back, we spent the next year building exactly what we had written. That was the first time that we had a vision up front, which we followed until the end.
PSB: Which element of the game are you most proud of?
JG: I’m personally most proud of the story elements. In those days you didn’t see video games dealing with a lot of current topics (bio weapons, terrorism, secret government agencies working outside the law). Remember this was all pre-9/11. And we were doing some things with characters that you didn’t see often in video games: Teresa Lipan, the brains of the agency, was an American Indian female… Lawrence Mujari, the biologist, was an African-American male, Lian Xing, a Chinese female, and so on. We were making a real effort to make the characters as diverse and un-stereotypical as possible. We were also attempting to inject a higher level of realism into the game than we’d seen before.
Often in game development (even today), you’ll hear “Who cares? It’s just a game!” That kind of thinking really bugged me. I wanted characters to have real motivations, level objectives to make sense and fit into a story arc, locations to feel real and have accurate details. And we did some crazy things story-wise that we might not be able to get away with now. For example (spoiler!), at one point in the game Gabe is rescuing and inoculating test subjects, only Gabe finds out later that he was actually killing them because the vaccine was really a poison. And scientists would run up to Gabe and surrender, and we sort of forced him to shoot unarmed men in the head (well, they were evil scientists after all). Having terrorists blow up a subway in Washington DC — think we could get away with that now? Again, this might all seem pretty tame by today’s standards, but in 1999 it was pretty startling to be doing this kind of stuff in a console game. Oh, and the taser. We all really loved the taser.
PSB: How would you like Syphon Filter to be remembered? What did it bring to the video game medium?
JG: For what it was: the first of its kind, a mix of stealth and action, using real-world, current story elements and settings, realistic weapons and gadgets, with edgy story elements. As anyone in game development knows it’s really hard to be original, to come up with new ideas, new mechanics and new ways of playing. Syphon did all that and spawned a genre; so many games came out after us and were variations on the theme. In many ways, we were there first.

- The FMV cutscenes prior to a mission start feature the level music for the following mission. Examples include:
- while Benton is briefing to Gabe and Lian before the Georgia Street mission.
- as Gabe is running through the streets DC before the Washington Park mission.
- during the meetings between Gabe, Lian and Markinson prior to the Expo Center Reception and Rhoemer's Base missions.
- While Markinson is showing Gabe information on Syphon Filter before the Rhoemer's Stronghold mission.
- As Gabe and Lian are being debriefed by Mara before the Pharcom Warehouses mission.
- The font used for the logo and the back cover description is a slightly modified version of the Industria font.
- Syphon Filter is the only game in the series that features a training video.
- Syphon Filter is the only game in the series not to feature a multiplayer mode.
- Syphon Filter is the only game in the series not to feature Teresa Lipan or Lawrence Mujari, both of whom were introduced in the next game.
- Syphon Filter is the only game of the PlayStation trilogy with an equippable flashlight instead of the automatic night vision googles utilized in Syphon Filter 2 and Syphon Filter 3.
- Syphon Filter was released on the PlayStation Classic as part of the 20-game lineup for the North American release version on December 3, 2018.
- Mara Aramov is Russian, but her last name would more accurately be spelled "Aramova," because real Russian surnames have both masculine and feminine forms.
- Silenced (or suppressed) weapons are quieter than "loud" weapons (or normal weapons), but are still loud enough that hearing protection is required to prevent hearing damage at close range. In fact, it would be very difficult, if not outright impossible, to fire a silenced weapon at close or medium range without being noticed.
- Despite the armor-piercing performance of the K3G4 in-game, Gabe is able to recover completely intact flak jackets from enemies killed with body shots from the weapon.
- The Shotgun can fired continously while hanging, without the need to pump the weapon following each shot. In real-life, a pump-action weapon requires the user to pump after each shot.
- The Sniper Rifle features a computerized scope that includes information such as distance to a target's appendage, features that most sniper rifle scopes do not possess. It also also lacks a stock.
- The Nightvision Rifle is described as being equipped with an "SVDN2" night vision scope. In real life no such scope even exists, the SVDN2 name being applied to rifles which are modified to use the NSPUM (1PN58) night vision scope. The in-game model is shown with a standard PSO-1 scope and lacks the suppressor it is described as having in the description (although it functions as a silenced weapon regardless).
- The fragmentation grenades in the game are described as using ammonium perchlorate, an oxidiser normally used in rocket fuel, and even if they were used in grenades, the only device that would ever use them is a flashbang grenade, where it is used to generate a rapid reaction from aluminium or magnesium to achieve a non-lethal effect of blinding and deafening a target. The mention of this chemical in the weapon description is perhaps a result of an individual, or individuals, on the development team recalling the PEPCON disaster of 1988.
- The description of the G-18 declares that firing 9mm rounds at 1,200 RPM somehow makes it the "most lethal machine pistol" ever made. In later Syphon Filter games, the "pistol-machine gun" category grows to include full-size sub-machine guns, rendering this claim invalid. For example, the first magazine-fed Thompson submachine gun prototype, "Annihilator I," fired more powerful .45 ACP rounds at at a faster rate (1,500 RPM), and this is not even getting into whether lethality is best determined solely by firing rate.
- The M-79 depicted in the game is actually a Tru Flite 37mm Super Long Range Gas Gun incorrectly shown as able to launch high-explosive grenades. The real-life M79 is a break-action grenade launcher as described in the game, but this action requires the user to manually reload after each shot, greatly reducing its effective fire rate as compared to the in-game version.
- Mara Aramov survives being shot in the head during the Main Subway Line mission and appears during the Expo Center Reception and Dinorama missions, which take place one week later, without any sign of injury whatsoever.
- The instruction manual establishes Erich Rhoemer as a German national, but in Omega Strain's Zeus Files, he is listed as being from Chechnya.
- Mara Aramov's hair is red in Syphon Filter, but becomes blonde at the beginning of Syphon Filter 2, which is a direct sequel. Other aspects of Aramov's appearance completely change between the two games as well.
- The manuals for Syphon Filter, Syphon Filter 2 and Syphon Filter 3 indicate that the characters aged 2 or 3 years between each game. However, the second game continues directly where the first game left off and the third game picks up only a few months after the second game's conclusion.
- During the Base Escape mission, if Gabe shoots one of the fuel tanks rigged with C4, Lian will call him saying "Gabe, check your fire", and warn him about potentially setting one of the tanks off, even though Rhoemer caught and killed her during the previous mission.
- Inventory images of the G-18 show the weapon with its slide locked back, indicating that it is empty.
