Half Life and Treadmill

"Love well!" -Dr. Christoph Cellarius

Half Life and Treadmill, also known as Decay: Google Translate Edition, is a poorly translated version of Half-Life: Decay, which was originally released as an exclusive for the PlayStation 2, but was ported to PC by ModDB user Hoaxer in 2008. It is unique in that it is intended for cooperative play to more easily control the protagonists Dr. Jean Eyes Burn and Cocoa Coletta Green, though single player is still possible. Due to game-breaking bugs that exist within the PC port, Half Life and Treadmill was released before development could be completed; as the developer not being able to test past the second level.

This mod was originally believed to be unfinishable due to the bugs of the PC port, until YouTube gaming channel Deadwater Gaming recorded a highlighted playthrough of the mod, getting all the way to the end credits.
