Contrary to popular belief, this game is not based off of the movie Dawn of the Dead (There is even a cute little box on the front of the game that states that)
What could be more fun than running around killing zombies with pretty much any object you can find? This game is good ol' fashion gore.
I didn't find the storyline that exciting, but it's one of those games that the storyline doesn't much matter.
This is great game to let out aggression or frustration.
The tiny text problem (from what I'm told) is because the game is designed for newer (plasma/hdtv etc) t.v.'s.
Overall, I'd recommend it to any of my friends, even for a good laugh. It's one of my favourite games for 360.
If you're not sure about it though, I'd rent it or download the demo.
