Aljir Prison or Point 36 (codename) is a prison located in Siberia in Syphon Filter 2. According to Lian Xing, it was originally thought to have been shut down by Nikita Khruschev in 1954 as part of his reform program, but was later covertly re-established from unknown sources. It is where political dissidents are kept, all of which are females (it is a woman's gulag).
Lian Xing was kept here before working for the Chinese intelligence. This prison is playable in Syphon Filter 2 where wardens are guarding the prison. The levels are "Aljir Prison Break-In" and "Aljir Prison Escape". The female prisoners' hair were completely cut. Uri Gregorov was about to be executed at midnight, but Mara Aramov probably rescheduled the execution and Gregorov is to be executed earlier (perhaps at 11:45 PM at Sept. 12, according to the level's briefing). In the second level, a violent prison riot occurred, many prisoners are killed and several guards are dead (it is strongly suggested that Aramov killed the guards). Also, in the second level, Xing managed to rescue Gregorov and both fight their way out of the prison. They both jumped out of the prison wall into the nearby frozen-surface river and swam towards the rendezvous point where Gabriel Logan, Teresa Lipan and Vladimir Nedobryi were waiting.
In Aljir Prison, female wardens often abuse the prisoners physically and/or mentally while male wardens watch enjoyably. Lian Xing decided to help some of the prisoners. During the prison riot, Lian witnesses prisoners shot by the guards for attempting to escape. Gabe tells her through the transmission line that "she is not going to be able to save everyone" and she must stay focus on the mission (rescuing Gregorov).
- Aljir Prison is based on a real life former Soviet gulag in Akmol, Kazakhstan also named ALJIR, the Russian acronym for Akmola Camp for the Wives of Traitors of the Motherland, though it was also euphemistically known as Point 36. Much of Lian and Teresa Lipan's descriptions of the Aljir Prison match its real life counterpart.
