I know this is a rather old game. But I think Co-op and Versus modes are fairly new. A friend of mine bought a Nexus 7 and started playing this cuz it's new on Google Play store. Now a bunch of us are playing it. Being available for both platforms just makes it so much more widely played. One concern I got are hackers and cheaters tho. Anyhow, anybody play this game? Any tips? I will share what I found after a few days of playing if anyone is interested here.
