Minecraft on Xbox Live Arcade is getting its massive, game-changing update tomorrow, known colloquially as the Adventure Update. Update 1.8.2 brings creative mode, hunger, sprinting, new mobs, new food and new biomes, among many more fixes and additions.
The Adventure Update just passed Microsoft certification and is set to launch Tuesday, October 16, port developer 4J Studios tweets. Check out the complete change list on the Minecraft wiki.
After this update, 4J Studios may consider adding an Xbox-tailored mod system, or "taking the game in a different direction from PC."
