Alien Breed 2004 (sometimes AB2K4 or AB2004) is an unfinished and shelved game in Team17’s Alien Breed franchise, a series of Science Fiction-themed shooters largely inspired by the Alien films. It was announced as in development in 2003, and was shelved in early 2005
This is the second known title in the Alien Breed series to be cancelled, after the aborted PC first-person shooter title Alien Breed: Conflict. The game was reportedly being developed using the Snowblind Engine that Snowblind Studios had been using for the Baldur’s Gate: Dark Alliance and Champions of Norrath franchises.
In July 2009 Team 17 announced the development of Alien Breed Evolution for PlayStation Network and Xbox Live Arcade downoad services. Given that the videogame will be viewed at the same top-down perspective, it is possible that this game is actually the same as Alien Breed 2004, with updated graphics. [Info from Wikipedia]
