Grassy Knoll is a platform base CTF level. It is a smaller map, and is designed to keep all the action concentrated in a valley. In order to steal your opponents flag, you must first ramp onto their base. Matches move along very fast in this lush landscape.
The idea for the two platforms actually came from a friend of mine. As the earlier version of this level was two bases, but he felt that was done too many times. So I took the time to change it, and it worked out great. There is also some high ground areas that I put into it that can only be reached from the air.
