I'm a little late on this one, but just in case anyone missed it: Adult Swim recently released Robot Unicorn Attack Heavy Metal Edition, exclusive to the iPhone and iPod Touch and still available for the special launch price of $0.99.
Adult Swim's enchanting tour de force Robot Unicorn Attack takes a mystical journey into darkness. Gallop through a treacherous landscape of bones and talons, unleashing your wrath on exploding pentagrams and floating demons to the punishing sounds of "Battlefield" by legendary German metal gods Blind Guardian. Because sometimes you just need a rainbow and sometimes you need to rip open the heart of evil.
- No rainbows, fairies or fanciful meadows
- Heavy Metal Edition is available exclusively on iPhone/iPod touch
- Open Feint achievements and leaderboards so you can compete with your friends
