A great alternative to GTA and TMB on the GameCube. While certainly not as stellar as these two hallmark titles, well just have to stop complaining that there are no extremely violent games on the GameCube.
This game earns all of its M-rating. It's a capital M. There is more gore, rough language, and general disrespect for humanity in this game than in most prisons. If you go in with your eyes open or (God help us) even enjoy some of these things, then it can be bloody good fun.
If you think the idea of a game about driving around in a machine-gun-toting car while completely ignoring traffic laws and blowing away anything in your path sounds like fun, then you'll get it out of RoadKill.
