Minecraft has been a pretty big hit on Xbox 360. It's turning two years old (on that particular platform) today, so Mojang is celebrating by offering some deals on skin packs for your happy builders.

Starting today through May 18, the original "Birthday Skin Pack" and a new "2nd Birthday Skin Pack" are free. Those will net you characters from Halo, Fable, Banjo Kazooie, and Viva Pinata. If another skin pack strikes your fancy instead, all of those are 50% off through this weekend, with the notable exception of Marvel characters.
