Crazy addictive Zombie game (Free!)

So I was chatting with my friend yesterday and we were talking about zombies when he realizes he has to show me something on his computer. So he tells me about this game called "Survival Crisis Z" which is not only made single handedly by one person but he also just released an arcade game onto the Xbox Live marketplace. I had recently downloaded and played the demo for that game multiple times, plus I love zombies so I gave the game a try.

I don't know why but Survival Crisis Z is craaaaazy addictive. It's got adventure, rpg, survival horror and third person shooter elements. You just start off in a building and begin to walk around the city trying to find weapons, ammo, food and such items to keep your character healthy, rested and well armed against zombies that can attack you in waves at completely random times. Plus there are two factions of people who control the city whom you can ally yourself with or remain in the neutral position between the two. Besides the large city there's also an ridiculously sized underground sewer as well as a "compound".

Oh and you can unlock a character customizer too, so you can make your guy look like anything really because they are quite a few options to change him or her.

Just thought I'd share since I'm really enjoying this game right now --- Link to download the game/install instructions for Windows Vista users
