This mode is now fully implemented. To recap, turning on Murder Games essentially just turns on 1 life, last man/team standing wins. It defaults to starting without weapons on a forest map with weapons in the center, a la Hunger Games. We also have two afterlife options: you can set it to where when you die you play as a spectator or as a zombie. We made this mode because there's huge demand for it on Xbox Live.
We're playing this at 3pm CST today. Join us!
