This is a third-person shooter, based on the sci-fi franchise Stargate, in which players battle for control of the galaxy. Players can compete in several modes of play (e.g., "capture the flag," "deathmatch," and "capture point") as they traverse through temples, bunkers, and alien cities. Human characters use machine guns, sniper rifles, and pistols to kill enemy forces. More fantasy-based weapons (concussive shock grenades, staff weapons that shoot out energy blasts) are used by alien units. As players "run-and-gun" through levels, they will hear cries of pain when enemies are injured; realistic gunfire and explosions occur during the fast-paced combat.
