This game is a highly stylistic shooter with strong RPG and looting elements. The cell shading makes the game very comic bookish and the humour is very reminiscent of the original heavy metal although without the sexual overtones. The game itself has a decent difficulty rating, but the AI is pretty basic I can't count the amount of times an enemy splattered itself on my vehicle. That being said, the enemies make up quality with quantity. The online mode is quite entertaining especially the co-op modes. The game consistently throws some enjoyable curve-balls at the players and the quests are nicely varied. The random loot generator is a lot of fun and while it doesn't feel like there's a bazillion guns, there's probably a good 50 different weapon styles beyond that just the stats differ. The game makes good use of the Mature rating, its not an orgy of "f"bombs or overly ridiculous sexual references. Its a bloody game with gruffly speaking people. And that makes all the difference. The little voice acting there is, it top notch, almost makes you wish that there would be more of it.
There is tons of replay value in this game, always something new to explore and a nice reward system for being adventurous. There's not quite so much to do as you would find in fallout 3, but that to me is the fun of this game. There were times in Fallout where there was just too much to do, too far to travel; and in the end it became a grind. While the themes are similar, this game is all action and fun. I would have liked more of a plot and more voice acting, but in the end I don't really need it in a shooter like this.
