The Battle Royale trend has made its way to the IO scene. Fight it out to be the last one standing in The Hunger Royale.
Simply move around with WASD, and aim with the mouse. If there any any items on the ground, snatch them up by left clicking. Then kill kill kill. While also maintaining your hunger so that you don't start to death.
While teaming is certainly frowned upon in many circles, it is a fairly fool-proof way of dominating the match. You can also use the shop to disguise yourself as either a crate or a supply drop.
