Checkout Famitsu's site for a bundle of new screens for the upcoming "walk around with your DS" Pokemon style game. As expected, once you find a Gaust on your scanner you can either capture them by lowering their health first or, you can just defeat them for XP.

It's looking better than Pokemon, I'll give them that.
