Warhammer 40,000: Squad Command - Essentials (PSP)

Squad Command is a turn-based strategy game set in the Warhammer 40,000 universe. Players take control of six squad members who fight the forces of Chaos over fifteen levels. Players spend action points in the game to move their units, fire on enemy locations, or improve their accuracy. Players have the option to outfit their squad members before each mission, eventually drawing on over twenty ranged and melee weapons. In addition to the single-player game, Squad Command also has three options for multiplayer gaming.
