Has anyone downloaded this game from PSN or XBL? It's a side-scroller where you stab, shoot, and blow up your enemies. It's brutal in a cartoonish way and really fun. The official soundtrack is also free to download from the game's website. Here's a zip of the soundtrack. http://www.shankgame.com/wp-content/uploads/Official-Shank-Soundtrack.zip
If you're unsure about buying this game you can download the demo. I suggest you try it out.
