Operation Flashpoint: DR (Game)

Operation Flashpoint: Dragon Rising is a first person tactical military game for Microsoft Windows, PlayStation 3 and Xbox 360 developed by British game developer Codemasters. Codemasters has advertised the game as a tactical shooter designed to represent modern infantry combat realistically. It is an unofficial sequel to Bohemia Interactive's Operation Flashpoint: Cold War Crisis, but was developed entirely by Codemasters due to a falling out between the two companies.
