This is my new Spleef arena. It includes an entrance for spectators, a preparation room for the contestants, and dual-level viewing. (Glass top for spectators so they can view the game from above)

The arena is made out of Netherack, and lined with fire for a fierce-looking touch. In my next upload, I'll create several chests of Netherrack in the preparation room so it can easily be replenished.

Have fun!
