Classified: The Sentinel Crisis

Classified: The Sentinel Crisis is a 2005 first-person shooter video game developed by Torus Games and published by Global Star Software for the Xbox. The player takes the role of a super-soldier with "intelligent" military technology created under the titular Sentinel Project. In contrast to other first-person shooters with multiple weapons, the game features a single weapon, a "multi-function rifle", that is slowly upgraded over the course of the game. The game was developed by Australian studio Torus Games, who created the game in a compressed timeframe and experienced difficulties developing for the Xbox.
