How about some Worms, er, Zwok?
To play the game, you've got to sign up. Don't worry, it's free. You then customize your little character... is that a Zwok or just a really ugly thing? Whichever it is, you make it your own. There are two teams for every match: Blooz and Grienz. Yes, that's "blue" and "green" in crazy-speak. Choose a weapon to fire, get into position, and let loose. Seriously -- this is Worms. Regardless, we'd love to see something like this on the PS Store. Wouldn't you?
