This capture the flag arena, designed for 4-12 players, contains two sides separated by obsidian, with wood and ores on each side for players to gather resources and gear up. A no man's land between the obsidian walls contains lava and diamond blocks to encourage early aggression. Games last from 5-20 minutes.
Vanilla command blocks are used to clear player inventories, teleport them into the arena, and reset the map after each game. CraftArrows and MCMMO are fun plugins to add, but no mods or plugins are necessary.
Paste the schematic around height 64. It uses the area below ground to store the original, so y=5 on a default superflat world will not work.
