Annihilation is a team-based PvP gamemode with 4 teams, Red, Blue, Yellow, and Green. Your team's objective is to destroy the other 3 team's nexuses, while protecting your own. Each team has their own quarter of the map where they can gather resources, build defenses etc. Every player is in adventure mode, meaning block breaking is only possible with the correct tools. Your team wins when it is the last one with a nexus.
