For the first time, you are given control of the new Governor of California, and as the killing machine from the future; the human resistance fighters program you to (once again) go back in time and save John Connor. Okay, most of us should be familiar enough with the
Terminator storyline that I don't have to give a lot of back-story.
Basically Terminator 3: Rise of the Machines has you, as the T-850 Terminator, play out a lot of the major events of the movie, as well as the events leading up to the Terminator's mission (getting the necessary supplies to go back in time). You will run around killing most things that move; the only characters that you won't be gunning down are your allies (resistance fighters, Connor, etc), but don't worry, they don't suffer from friendly fire.
T3 starts off when the Terminator has been revived and you must collect the necessary parts to build the time machine. This makes up the first four levels of the 10-level game. Along the way you will deactivate Skynet and destroy other Terminators, as well as various other robotic baddies. Once in the past (present), you will hook up with the future rebellion leader and try to keep him alive while the TX goes after him.
There is a wide assortment of weapons to gather throughout the game, everything from a shotgun, to a small machine gun to futuristic Plasma Guns and Stingers. There are also a variety of secondary weapons that will help as well. These include grenades, flash bombs and C4.
One aspect that I found annoying about Rise of the Machines is its password based save system. This feature tends to come off as a cheap aspect. I mean, if you can get all the needed information out of five characters, then go ahead and make a save feature.
There are two multiplayer modes for Rise of the Machines, a four-player Capture the Flag and a two player Co-Op Mode. These features aren't horrible, but seem to be more of an afterthought at times.
