Arenas

One arena is live at a time and it changes every 30 minutes. During the last minute anyone can /vote for the next map.

Colosseum

Sandstone ruins around an open middle, with a river splitting the map in two. Most fights end up on the bridges.

Overgrown temples, ponds and a lot of trees to hide behind, which works for you and against you.

Netherrack, lava pools and a few towers. People fall into the lava more often than you'd think.

Snow and ice with a frozen canyon down the middle. There isn't much cover anywhere.
