This PVP arena has 5 teams/ fighter rooms. There is also a "command booth" which has a "release figters" lever. This lever is connected to 5 sets of pistons that go down when the lever is activated to release the fighters. As you may notice in the fight rooms there is a button to get in but not one to get out. That is there because when gladiators fought, once they got in the arena, they weren't getting out, unless they won of course. There is also a chest full of diamond swords per fighter room. Take one for each fight. Enjoy the PVP, and feel free to customize the map anyway you want. P.S. If you're digging around and you notice unused redstone underground, that is redstone i was using for a firework dispenser you could activate from the command booth. Dont mind it please I was too lazy to destroy all of it.
