Members - Team Fortress: Invasion mod for Half-Life 2

Team Fortress 2: Invasion is a project that is set out to finish the long-lost cancelled War Of the Worlds themed TF2 game. It's been described as being RTS-like and on a much bigger scale. The source code for this was leaked in 2003 and then again in 2012, some comments and parts of the code indicate this game may have been cancelled sometime in 2003, before the leaks occurred.
