6GUN is a third person, tactical-action, modern combat game. In 6GUN you are the leader of an assault team in the highly classified GUNSLINGER program operated by the Special Operations Command (SOCOM). When diplomacy fails, and the US government needs a "deniable" military solution to its problems abroad, they call on the GUNSLINGERS. The game features four campaigns and 12 levels. Gameplay ranges from small unit combat, to close quarters battle (CQB), hostage rescue, demolitions, sniping from a helicopter gunship, and High Altitude Low Opening (HALO) parachute insertions.
