This is my take on the classic HL2DM map, aim_arena.

I chose to work from the b4, versus the b6 version, becuase I was willing to sacrifice eye candy for playablility.

Aim_arena is a great map, and provides a quick paced game, but when you have more than a few players on it, it becomes very crowded, so I've expanded it out to double the size.

I have changed very little else, other than doubling the map to keep the spirit and game play as close to the original as possible, while giving a little extra breathing room.
