Robot Unicorn Attack 2 surprise release on App Store
Robot Unicorn Attack 2 for iOS devices is currently leaping its way westward from New Zealand, with an expected arrival in North America overnight. TouchArcade reports the basics for the sequel stay the same, as players control a rainbow-tailed ever-running unicorn until failure catches up with them.

Changes from the first game include prettier levels and a unicorn customization feature, where players can unlock modifications by collecting tears. The game is free-to-play with tear packs available for real money.

Likely the most controversial change is that Erasure's "Always" is not the game's default track. Adult Swim Games Senior Producer Chris Johnston tells us the reason is music licensing, noting, "Which is partly why the original RUA never went free." The game now features original music by Module.
