MooMoo.io is a multiplayer survival game where every player starts with nothing but bare hands on a big shared map. You punch trees, bushes, rocks and gold to collect wood, food, stone and gold. Then you turn those resources into walls, spikes, traps and windmills to build a base that other players will want to break into. It plays like a tiny real-time strategy game and a brawler at the same time.
Gathering resources earns experience. Each time you reach a new age you pick one new item or weapon, so no two players end up with the same kit. Windmills slowly produce gold and score while you are busy. Walls and spikes keep raiders out. Food heals you when a fight goes wrong. You can also join a tribe or create your own, which lets friends build next to you and share the defence.
