If you’re a fan of things that are awesome, you should be intimately familiar with Robot Unicorn Attack [$.99], Adult Swim’s popular Flash game that rainbow dashed itself onto the App Store in mid-2010. If you aren’t familiar with the title, well, I’m not so sure we can be friends. Robot Unicorn Attack is an endless runner that is chock full of robot unicorns (duh), magical fairies, a pod of leaping dolphins, and colorful visuals that would make any 7-year old girl (and myself) squeal with delight. All set to a looping soundtrack of Erasure’s Always.

Robot Unicorn Attack was such a success that it saw two follow ups on the App Store, Heavy Metal Edition [$.99] and the festive Christmas Edition [$.99]. A few months back, all 3 RUA titles were updated with Retina Display visuals, something fans had been clamoring for since the release original release of the iPhone 4. Today, the original Robot Unicorn Attack got another dose of update love, turning it into a Universal build and improving its performance on all devices.

If you recall, the Retina Display updates to the 3 RUA games were kind of staggered, taking about a month for all 3 to finally receive their updates. This means that it’s possible the other 2 RUA games will be getting a similar Universal treatment, though I haven’t heard confirmation of this just yet.

Also, in kind of a strange move, the iPad native Robot Unicorn Attack HD has disappeared from the App Store. It makes sense with the new Universal version to not have 2 iPad versions, but I don’t really know what that means for previous owners of the HD iPad version. We’ll be getting to the bottom of this query as well as what’s in store for the other Robot Unicorn games, but for current owners of the original release make sure to grab the latest update, throw that bad boy on your iPad, and rainbow dash your way to ultimate happiness.
