One of our long-time favorites around the TouchArcade offices is Adult Swim's Robot Unicorn Attack [99¢/HD], and to a lesser extent its siblings Robot Unicorn Attack Heavy Metal Edition [99¢] and Robot Unicorn Attack Christmas Edition [99¢]. I say "to a lesser extent" not because we don't enjoy the gameplay as much in the latter two titles, mind you, but because it's a scientifically proven fact that humans are incapable of enjoying any game more than one that runs Erasure's Always on an endless loop as its soundtrack, even if the gameplay is identical in each game. You can't argue with science.
Anyway, Adult Swim Games has just released new updates for the regular Robot Unicorn Attack as well as Heavy Metal Edition which add Retina Display optimized visuals into the games. This is something I've personally wanted ever since the release of the iPhone 4, and I've heard many requests from other users since then as well. But, it appears that it wasn't as simple as just flipping a switch to enable Retina Display in these games. Much of the artwork looks to have been redrawn and reworked, which could explain the delay in bringing these updates to market. You can see before and after examples in the screens below (click to enlarge):
At any rate, they both look fantastic now. It's a huge step up from the blurry, jagged visuals Retina Display device owners have been enduring for the past year or so. The Christmas Edition version of the game has not been updated, and it isn't clear if there are any plans to do so. But, with Christmas looming next month, perhaps Santa has a graphical update waiting in the wings for our Rudolph-costumed unicorn? We'll have to wait and see, but in the meantime, be sure to update your copies of Robot Unicorn Attack vanilla and Heavy Metal Edition and enjoy the new eyeball-scorching crispness.
