The forthcoming 1.8 “Adventure Update” of Minecraft adds randomly-generated villages, a more refined control system and game mechanics, larger and more realistic ocean and mountain biomes, and the Endermen.
If you never look directly at Endermen, shadowy creatures with long and narrow limbs, they don’t even notice you. But once you do, they turn and stand and look at you, too. As long as you’re looking directly at Endermen, they’ll stay put and you’ll stay safe. “As soon as you look away,” creator Notch writes, “they will run (very fast) towards you.”
