See: How do I install a map or mod?
I tried my best to say something bad about this map, but i couldn't. It is a classic duel map, a with a bit boring but flawless layout; we certainly need more maps like this. It also seems to be the first map up there that utilizes scroll limit technology to produce beautiful off-screen terrain.
Most of the battle certainly happens in the middle, for it is the shortest way to the enemy (around 2 minutes by truck, which makes it a map of well-balanced size), but highgrounds are good for setting up proxy factories and repair facilities and are certainly of strategical value. The paths are narrow enough to be walled in at critical spots against flamer spam, but not narrow enough to allow effective turtling.
