‘Operation Sourcecode’ is a platform game in which the objective is to collect USB sticks with sourcecode on the various levels of the game. The game is set inside the developer AE’s offices, and is filled with crazy enemies!
This is the installer for Operation Sourcecode. It assumes you haven't installed Microsoft XNA and will take care of it for you, in addition to installing the game.
It doesn't work. I think it uses files from folder TiledLevel situated on yours desktop and may be some other wrong ways.
