Official Map Description
This is the ladder edition of a GSL tournament map.
- Backdoor third expansion with Destructible Rocks on it.
- Two Xel'naga watchtowers in the middle.
- Several line of sight blockers in the middle and next to the backdoor expansion.
- Polar Night Naturals are not symmetrical and can't be walled of using the same building composition. 
Because of how the natural, third, and fourth are placed, Mutalisks can easily go from one base to another, destroying many workers in the process. Zerglings, Hellions, Phoenix, and Banshees can all make use of this feature.
