In a time of cold and lonely nights in December 1993 when people were hunting demons on phobos, there were still more demonic aliens hiding in the dark. Well hidden, they rarely made it out of the shadows of thy Doom.
Roughly 2-3 months before Doom and Blake Stone would be released, the development of Corridor 7 had started. We are entering the year 1994 and there is a thirst for more. Soon after, Corridor 7 was released.
It is not unlikely that due to the late start on development things were more rushed. Rushing things seemed to be generally a Capstone Software trend.
This was still many months before Operation Body Count was even in development. For some reason many websites tell you that Body Count was released first, which makes as much sense as terrorist-trained killer rats.
This is a short summary of an early build (JAN 1994) of Corridor 7.
Trying to be more less accurate, there might be some errors and some sections are incomplete. The audio, especially the sounds, still need a closer look as well as the AI and small gameplay adjustments.
