Jens Bergensten, Minecraft Lead Developer, is bringing his new title, Cobalt, to Xbox consoles this October. The game is not being developed by Minecraft developer Mojang, but by Oxeye Game Studio (Mojang is collaborating on the project though). Oxeye Game Studio was co-founded by Bergensten as well as Daniel Brynolf and Pontus Hammarberg.
Cobalt was originally only a PC title. As well as Xbox One and Xbox 360, the game will also be available on Steam this October.
