Conflict: Vietnam is the third game in Pivotal Games' Conflict series, this time going further back in time to the bloody battleground of Vietnam. The game is set during the Tet offensive in the year 1968.

The player takes over the roles of four soldiers who aren't, contrary to previous games, elite S.A.S or Delta Force soldiers. In fact, they are normal American G.I. who are separated from their unit during battle and have to fight themselves through enemy territory with hordes of hostile Vietnamese.

Game can be played by issuing orders to every member of the squad or directly taking control over one of them. In every mission, there are one or more main and several bonus objectives, like destroying all tanks in the area or collecting Vietcong documents. For each achieved objective, killed soldier or destroyed vehicle, squad members get experience points. Each one of them has different abilities (Sniper, Leader, Heavy Weapons, Medic) which can be improved with these points. To defuse one of the numerous booby traps, it is necessary to have skills in that ability.

The levels are set around the jungle and include underground Vietcong complexes or temples. In addition to enemies, friendly characters like allied soldiers or citizens can be encountered and talked to, with some of them giving bonus objectives to complete. Furthermore, some missions involve the use of stationary weapons like machineguns and driving jeeps or tanks.

The console versions of Conflict: Vietnam feature a split-screen multiplayer co-op mode with up to four players (Xbox), or two players (PS2). The PC version doesn't have this feature.
