Portal 2: Desolation - Official Teaser

Portal 2: Desolation is a free mod for Portal 2 which is currently on Steam Greenlight and is being published by Corrupted Studios. Steam Greenlight: Moddb: Synopsis: You wake up in a 1976 Extended Relaxation Annex stasis chamber, one of many lodged in a ruined office complex located near the base of Aperture Science Innovators after an incident with details scarce to the player. The facility rumbles silently as dust and rubble tumble down upon you from the layers upon layers of now unstable, obliterated areas visible through wreckage above. Something tells you that this place has been empty for quite some time.
