As games like Call of Duty were really big at the time, in 2005 / 2006 Terminal Reality created a prototype / demo for a military FPS set in Iraq, to pitch it to various publishers. One of these publisher saw the demo and loved it, but said they wanted to make a different game, not a military shooter. That “other” game became the new Ghostbusters which was released in 2009 for Xbox 360, Playstation 3, PS2 and Wii. The military shooter remained just a nice tech demo and never became a full game.
Thanks a lot to Bob for the contribution!
