You guys are in for an interesting map. Can't say much without being a leaky faucet, but might be a good idea to brush up on your outside the box playing.
The only thing I wish to make Legions: Overdrive even a better game, is water. With water, the game would be so cool, the ability to stay over it and to go deep on it... Oh! And by the way, the map is looking good, some tunnels would be amazing!
