The game's vehicles feel like an afterthought. For the most part, they're all variations on a theme. You've got the dune buggy with a machine gun mount, the burned-out car with a rocket launcher mount, armored personnel carriers with laser cannons, and so on. Other than the Skynet FKs, there are no airborne vehicles. The vehicles aren't much fun to use anyway, so you probably won't be spending much time driving. Even smaller cars, like the dune buggy, accelerate slowly and handle like pigs. We also managed to get vehicles stuck on top of burning trash cans and in first-story window frames, which should give you a pretty good idea of what to expect from the physics in the game. Terminator 3 seems to also have trouble with collision detection. Enemies don't react to taking fire, and, in many cases, rockets and lasers will actually blatantly pass right through character models and hit the ground behind them.
Terminator 3's bot AI isn't the smartest we've ever seen.
There is no single-player campaign in Terminator 3: War of the Machines. From the menu, you're simply presented with a list of the game's 12 maps and are given no other options. You aren't allowed to play against the computer in team deathmatch or mission-based modes, as, apparently, the game's AI is programmed to only handle the termination mode, which is basically the same as Battlefield 1942's conquest mode where teams battle for control of various bases on the map. You can't even set a specific time limit for single-player games! The bot AI is decent enough at deciding which bases are appropriate to attack, but they offer very little challenge as far as actual fighting goes. Any experienced shooter player should easily rack up an astronomical number of kills. It's also worth noting that the bots don't use the vehicles much, and when they do, they have a lot of trouble navigating even the simple maps.
On the multiplayer side of things, there are very few people playing online, and there are no dedicated servers available. For a game without a meaningful single-player mode, it's shameful for Atari to not have set up even a single dedicated server for the game. At any given moment, you'll find two to five Terminator 3 servers, which seem to all be hosted off of someone's personal computer. In our experience testing online, we frequently found our pings spiking up over 700ms, which makes aiming just about impossible. Even if you're lucky enough to play at a steady 100ms ping, the hit detection hardly works at all.
It's not often that we run into a game that has so little redeeming value, but Terminator 3: War of the Machines fits the bill. With its lackluster graphics and sound, poorly designed maps, shoddy network code, and no online community support whatsoever from its publisher, Terminator 3 should have been terminated long ago in the production process. Unfortunately, no one had the guts to say "Hasta la vista, baby!" to the project.
