Z0MB1ES!!!1 is the best game on the indie games channel.
If you've played Katamari, you know that what-the-fuck feeling you get the first time you play a game that is truly bizarre. This recent XBL Indie Games Channel release is a culturally American Katamari Damacy. It has zombies, rock music, and guns... what could better represent American culture than that? These slices of America are delivered in such a way to make you wonder exactly what it is you have just experienced.
The action is very intense but it never feels you have less than razor-accurate control over your fate as the game plays perfectly. This genre is simple by its nature, but it can certainly go wrong. This game is no example of that. Instead, it is one of the most highly polished and entertaining games on the indie games channel. At a dollar, it should be an instant purchase.
