Yea I'm probably the last person would would try(let alone actually pay for a zombie game app but this one is cool...try the lite version if you haven't yet. You setup turrets to shoot zombies to save your shack(house) and yourself of course. You can setup a whole bunch, or upgrade to a few powerful ones, etc. Not to much strategy to be complicated yet not so dumb to get boring really quick. Post tips if you've played, I'm going to go buy the full version now =) ..only my second paid app, scrabble being #1.
