This map is 4-way symetrical making it ideal for multi-team varients. The map consists of four rooms for the different teams, and two central rooms (two floors). This map works well, but even though I haven't gotten enough people to play a multi-team game on it (we had to 3v3), it plays awsome. Very simple layout, but the center battles are massive.
For esthetics, I put "idols" of each colour in every corner. They're actually in action poses. I originally had them attacking the buildings, but that allowed people to grenade jump onto the rooftop using the idols, do I had to squash that idea. Anyways, this map isn't fully done yet, still lookin for suggestions and feedback, and if you want to help me test this map, I'm looking for seven people to have a full multiteam battle.

This map is setup for EVERY gametype except infection. Works best with slayer and neutral flag/bomb and especially good with king of the hill and oddball. This map is designed for Multi-team varients, but works just as good with two team objective.

OVERVIEW

Outside of Yellow base

Upstairs of Center room

Downstairs of center room

The Red "IDOL"

The blue "IDOL"

The Yellow "IDOL" ..... yes, he's been speared by the blue idol.

The green "IDOL" got himself messed up by the red idol.

I had to have the Green and Yellow idols be dead cause there isn't any lights their color. This way, it seems their life has faded away. Whatever.
