It plays both ONS and CTF and is designed to be a lot like the Tribes games. Quite simply its very large and doesnt have a huge amount of detail. It took me quite some time to get rid of lighting errors that kept appearing so hopefully there shouldnt be any left. Its my first time playing with ImgToMap as well which... may explain the scale.
The heightmap is actually a genuine tribes one and one of the few symmetric ones.
