Classified: The Sentinel Crisis is a budget video game for the Xbox. It was developed by Torus Games and published by Global Star Software. The PlayStation 2 version was cancelled due to negative reviews before release.

You play as a mutant super-soldier resembling Master Chief, wearing the military's new "Sentinel" suit that makes him stronger, auto-heals him, and targets enemies. A group of terrorists have managed to find out about the Sentinel suits, and have kidnapped a scientist that helped develop the suits. You must destroy the terrorists and make sure that the Sentinel technology does not fall into the wrong hands.
