1.4 Red vs Blue Multiplayer Map

Red vs Blue Multiplayer Mini Game Arena Map

So 1.4 is here and with it comes the command block. This map has been a project of mine for months but only with the pre 1.4 snapshots have I been able to add the game mechanics. With inspiration from Sethbling and Hypixel's TF2 Dustbowl map, I was able to finish this in time for the 1.4 release.

Features:
This map contains 7 arenas each with their own rules and play styles, with different game modes like CFT and death match.
Three of the arenas feature choose and class, with 5 classes each with their own unique abilities and gear.
Battle with your friends, for 2 or more players.
Fully set up command block network with teleporters, item distributors and gamerule mechanics.

Requirements:
Minecraft 1.4
Minimum of 1 admin (in creative) to control the games
and 2 players (in adventure) 3 out of 7 arenas are playable with this minimum but the more players the better!
Use any texture pack
(though one with easy to see through glass and a clear difference between reds and blues is best)

Useful Gamerules:
doMobSpawning false
mobGriefing false
commandblockOutput false

- My first published map so feedback is welcome, spot any problems let me know :)
