Anyone try out the demo yet? It's basically the first Crackdown, but everything is 10% better and they added zombies. I personally can't wait to pick it up.
I've been playing it for a few days and it's pretty fun, I'm excited to get the full game. When it first came out there was a glitch that let you play for an unlimited period of time but they have since patched it. There are some times when the zombie "freaks" are a bit much though, it makes it impossible to drive or walk down the street without hitting a bunch of them.
