What is HeavySpleef?
Spleef is a gamemode in Minecraft where your goal is to knock out players by destroying a floor so the other player falls down. If a player touches a losezone he is out of the game. Last man standing wins... With this plugin you can easily setup games without much knowledge. Just define a cuboid with the built-in selection system or make a cylinder game and add a lobby point and a floor. After that, the game is ready to play!
