"You'll never look at gas stations the same way again"
And I love it. It's up there with my favorite Xbox 360 games. Actually, my favorite 360 games are Full Auto, PDZ, and Condemned.
Back to the actual game. The game feels and looks a lot better than the demo. There are a few game modes, and all are decent. Career can be very addicting (get that gold medal), Arcade is fun to just play, head to head is fun with a friend, and Xbox Live is very good.
The twist FA has on normal racers is guns. Big guns. That can destroy EVERYTHING (almost, at least). And Unwreck. Unwreck is a nifty feature where you can rewind time and try again. This is especially cool sice there is a lot of you blowing up and cool shortcuts to rewind and try to get to again.
There are some standard modes of racing. Regular circuit racing (think laps), there's down and back (think go, turn around, go back), point to point, (think start here, go there), and others.
There are some neat (non-liscened) cars, and non-customizable weapon packages as well as a bunch of tracks, even if some tracks are oddly like another.
This all controls well, except that the real fast cars get really floaty, and there are some rather odd car physics, like when you hit a rock and fly straight up. It's nothing too bad, but worth mentioning.
Graphics are excellent. I've had people come up to me and say "those graphics are real nice". They're an obvious upgrade from the demo. Nice and shiny, with some awesome smoke and explosion effects.
Between Techno beats, engine roars, weapon clatter, and explosion and breaking noises, the sound is excellent. Turn it up real loud for and adrenaline rush like no other game I own.
All in all, Full Auto is one of my favorite 360 games. I think anyone should try it, even if just to rent it, but I think this deserves every penny of the $59.99 (w/o tax).
