Custom Skins on MCX360?
While the XBLA version of Minecraft is, in many respects, very similar to Beta 1.6.5, a number of features were brought forth a little ahead of schedule, just to make the game that much better. Of course, more updates are on the way as they bring it up to speed with the PC version, and likely some gems designed specifically for the console. One thing that has come up a lot since launch is custom skins, and players will be pleased to know that they are not far off! Currently it is believed that the skins will be DLC for the game, although the specifics are not currently known at this time. Bear in mind, this can change between now and the release of skin customization, so keep an eye out here as we gather more information!
