Yeah, just picked this one up recently. It's a heck of alot of fun building your dudes and the fact that it balances so well. Want cavemen versus cyborgs? No problem! Aliens brawling with a beholder lead gang of slimes? Sure!
The mechanics are pretty simple but allow alot of strategic options (the ability to gauge and flank opponents as well as forcing repositions is really cool).
I highly recommend this game for someone looking for a great, flexible skirmish level game. Link to Unified Theory homepage:
