I just wanted to introduce an AWESOME map that I have the privelage to share with you. First, it started with the drawing of a halo base, to which I had the idea for a mine map. But I was/am a noob modeler and map maker, so I got the help of gecko753, who put in a lot of his time into this excellently made map. Pictures (sorry that they are really small):
The Tower

The Mine Itself (You want to experience it yourself to see how truely vast it is)

An exit of the mine

Gernades at the blue base

The blue base is the building, and the red is the mine underneath. I think this is a very well made map, and all the glory should go to Gecko. Thanks.
