Caliber 50 (Ver. 1.01) — About this game
Caliber .50 follows a captured pilot fighting out of a Vietnam prison compound. Guns and grenades provide different ways to remove the soldiers blocking the escape, with collected weapons changing that attack to a machine gun or flamethrower. Some enemy vehicles can also be taken, giving another means of crossing a defended section. Learn the ordinary firing line before collecting a different weapon, then check what the new attack covers instead of stepping into the same range by habit. The escape route belongs to the original arcade mission rather than the longer home-conversion rescue campaign.
