Terminator 3: War of the Machines will place players at the very center of the conflict outlined in the Terminator world- the war with the sentient machines. The battle will rage in single and multi-player modes across a variety of vast landscapes taken straight from the upcoming theatrical release, Terminator 3: Rise of the Machines, including downtown Los Angeles, a ruined ocean harbor, devastated highways, Tech Com and SkyNet bases, crumbling factories and more.

In Terminator 3: War of the Machines' vast multiplayer mode, players will compete online as either a member of Tech Com or as a SkyNet Terminator model. Eight playable character classes are available for SkyNet and Tech Com forces and up to 32 players can wage ware in each server. Humans will have the advantage of cunning and stealth while SkyNet will bring to bear the awesome power of overwhelming force, brutality and durability. Each class will offer unique advantages and disadvantages in numerous battle situations. For example, SkyNet T-900 Endoskeletons can utilise their unique vision to quickly and easily identify even the most camouflaged opponents, but will be unable to heal or repair themselves in combat like their human counterparts.

In the single player campaign, players will power on as the Terminator himself, Arnold Schwarzenegger, with full likeness and voice acting, to wage war alongside SkyNet's mechanical forces against the human Tech Com revolutionaries. Once captured, however, the player is reprogrammed by Tech Com to fight for the humans and the player battles against his former robotic allies.

Weapons in Terminator 3: War of the Machines will run the gamut from modern day and near-future weaponry, such as the M4A1, Desert Eagle and X-29, to the futuristic weapons used by SkyNet, including phased plasma rifles and cannons.

A number of armored and weapon-equipped Tech Com and SkyNet vehicles will be at the player's disposal both in single- and multi-player modes. Vehicles included modified trucks, cars and personnel transports for the humans with mounted guns, plasma rifles and rockets. SkyNet vehicles include a variety of land and air-based machines. These vehicles act as the classes for the Terminator team, meaning the gamer plays as an FK hover attack craft or HK tank, rather than manning them from the inside. In addition, the player will be able to call in air strikes by targeting an object and issuing commands to offscreen allies.

Terminator 3: War of the Machines will release for PC in Winter 2003.
