Massive Canyon for big battles.
Beware that bots can traverse all center hills, while vehicles can only move through the canyons.
Only the shoreline cliffs are too steep for bots.
Also the canyons have superb grip and offer a 20% speed bonus.
The water is however treacherous with strong currents, making movement their harder and 20% slower.
Thanks to Bacon for the canyon detail textures and Beherith for the original map!
