This game has (so far) been released three seperate times under three different titles. First there was Shadow Force: Razor Unit, then it was bundled and retitled Operation: Shadow Force and most recently was rereleased as a stand alone game called Delta Ops: Army Special Forces. Though the title changes, the game is exactly the same.
Curious about the door in the Tutorial with the "No Admittance" sign? Kill one of the first two GIs and terrorists will come streaming out.
