Vietcong is a 2003 tactical first-person shooter video game developed by Pterodon in cooperation with Illusion Softworks and published by Gathering for Microsoft Windows.

Vietcong: Purple Haze was also released in September 2004 for the PlayStation 2 and Xbox, ported by Coyote Games.

The player takes on the role of Sergeant First Class Steve R. Hawkins, assigned to the United States Special Forces ("Green Berets") camp at a strategic location of Nui Pek in South Vietnam near the Cambodian border.

The game ends in a massive North Vietnamese attack on the team's base camp which is ultimately abandoned by all American forces.

Vietcong has the player take part in military operations against the Viet Cong and later also the North Vietnamese Army.

Some levels are highly linear, while others take place in more open outdoor environments, allowing for more tactical freedom.

Gameplay mostly revolves around open combat in the jungle, tunnels and other locations typical for the setting but the player occasionally also has to traverse longer passages without encountering enemies during which punji pits and other traps pose the main threat.

The game avoids the use of health packs and rather has the player use bandages, which briefly exposes him, or have a medic treat his wounds.

By default the team simply follows the player character and engages at will but general orders such as to attack the enemy or retreat can be given.

The latter allows the player to simply engage in a fight on one of several arena-like maps with the sole objective of eliminating all enemies.

VietCong: Purple Haze is now playable online again on the replacement Xbox Live servers called Insignia.
