Chunk Wars is a team-based attack-defend minigame for Minecraft. You play in an arena of different Chunks, all carefully handcrafted to replicate different Minecraft biomes and structures as closely as possible. Along with your team you will face everything that vanilla Minecraft can throw at you. Your goal is to be the last team standing.
