Corridor 8: Galactic Wars

Corridor 8: Galactic Wars was the planned sequel to Corridor 7, a first-person shooter by Capstone Software. The sequel used the Build engine and was supposed to be released in early 1997. However, Capstone and its parent company Intracorp Entertainment went bankrupt in 1996. One of the former developers published an early prototype including the source code and a design document of this game.

According to the document, Corridor 8 was planned to have 6 episodes with 10 maps each. The episodes were broken up into two sides: the human "Allied" and the alien "Axis", three episodes for each side. This game was also supposed to feature 18 characters plus 6 aliens redone from Corridor 7, 20 weapons to choose from and a secret weapon, and multi-player network gaming for up to 8 players.
