Psychological Instability's official pages are here and here. This is merely a backup.

WARNING

PSYCHOLOGICAL INSTABILITY IS NOT FOR THE EVERYMAN. In order to pass any room in Psychological Instability, you must have finished the main Portal campaign to the best of your ability. These tests require foward thinking.

About

Psychological Instability is a project being undertaken by jack5 and his GameBanana studio SM4LFA. It may not look like much from the screenshots at the moment, but it will most likely in future go as far as having a whole new set of textures, voices, models and music.

Original Soundtrack

The original soundtrack for Psychological Instability is out now and can be bought, but then again you could always cheat and grab the music from the sound folder. Not all of the songs from the soundtrack are in the current version of Psychological Instability.

Version Information

  • v1.02 (Current): Bug fixes in first and second chamber. Songs from the original soundtrack added.
  • v1.01: Bug fixes in first chamber. Second chamber released.
  • v1.00: First chamber released.
