The player controls 1st Lieutenant Thomas "Deadeye" Coburn, an American soldier in the Vietnam War. The plot follows Coburn's work in his unit, which is described in diary entries between missions. These diary notes give context to the 8 individual missions in the game. The missions generally follow a similar setup, with the player being required to kill Vietcong soldiers and then destroy an objective like an anti-aircraft gun or eliminating a Vietnamese sniper.
