Welcome, Gladiators, to the Arena! I made this map and its gametype for a friends birthday party and everyone enjoyed (apart from one, obviously insane person) so the map isn't that pretty (holes and wonky edges) but the map is really fun to play.
The map:
This is the arena, a small, multi-layered, symetrical room with lots of jumping to do.
The main level:

The Upper level:

The main level (again):

The lower level (and Grav ham spawn):

There are 4 Gravity lift spawns on the map that re-spawn every 10 seconds and a Gravity hammer right in the middle which respawns every 2 minutes.

The Gametypes:
There are 2 gametypes to go with the map, Gladiators and Gladiator hill (a KOTH variant of Gladiators (duh))
In the Gametype Everyone has 2x Overshield, 50% recharge rate, Energy swords (no nades) and infinite ammo. The way this is set up means that you can survive a sword lunge (just) but a Gravity Hammer lunge is still fatal. Slayer goes to 20 points and KOTH goes to 100 points.
The idea of the gravity lifts and the upper level is to:
1. Have a good vantage point of the level
and
2. Have a place to hide whilst waiting for your shields to recharge

The hill for the KOTH variant is right in the middle (the lowest level - where the Gravity Hammer spawns). I personally recommend the KOTH game because of the hectic atmosphere of it all!

The game in the video wasn't very good - all my opponents kinda sucked so I never had to go right to the top to hide for my shields to recharge. I also recorded a KOTH game but for some reason it's not on my file share :/
