Ballistic: Ecks vs. Sever is a cancelled FPS that was in development in 2002 by Zombie Studios and it would have been published by Bam! Entertainment for the Playstation 2 and later for the Xbox. The game was based on a 2002 action film with the same name, starring Antonio Banderas and Lucy Liu, often listed among the worst movies ever made. The project was officially cancelled in 2003, probably because of the low rates of the film and some quality problems of the game.
The GBA version of Ballistic: Ecks vs. Sever was developed by Crawfish Interactive and released in 2002.
