According to IGN, Adult Swim’s amazingly popular Robot Unicorn Attack [99¢] is about to be joined by an evil App Store twin. Robot Unicorn Attack Heavy Metal is abandoning the colorful platforms, rainbows, and sparkles for pentagrams, fire, and brimstone. Per IGN, the gameplay is identical aside from graphical changes, and one much more severe change…
The fantastic soundtrack consisting of Erasure’s Always has been replaced by the equally over the top Battlefield by Blind Guardian. Adult Swim usually doesn’t go public with their games until their release is imminent, so it wouldn’t suprise me to see Robot Unicorn Attack Heavy Metal pop up on the App Store any day now. In the meantime, Robot Unicorn Attack is still on sale for 99¢, and I really recommend checking it out or at least trying the free flash version if nothing else.
