What could be worse than some cretin named Big (who also happens to be your brother) stealing the pair of mystical underpants left by your departed grandfather? Nothing, as far as the folks at Black Pants Studio are concerned. With the team's first release, the sandbox-oriented action and physics game Tiny and Big: Grandpa's Leftovers, we get to see just what happens when you give a guy a raygun, a grapple-device, and unlimited rockets, then turn him loose in a sun-parched ruined desert world to find his pants-thieving brother. To put if briefly: a whole lotta rocks will get sliced, tossed, juggled, and destroyed.
