Yes, another free game.
Full Spectrum Warrior is based on a game commissioned by the U.S. Army to train light Infantry troops in urban combat situations. Soldiers are placed in a tense, hostile, and claustrophobic environment where they must complete a variety of military objectives. Players act as the Squad Leader, providing direction to Alpha and Bravo fire teams. The successful Squad Leader effectively uses cover in the environment and moves his fire teams in a coordinated fashion so they can protect themselves from possible attacks that could come from any direction. Full Spectrum Warrior puts you in the dirt with your men, where danger lurks around every corner.

Despite what the screenshot looks like, this is not a shooting game. It's more like a 3rd person, tactical based RTS warfare sim.
Had it on PS2, really not my type of game but sure some will like it.
