WW2 Walker
During WW2, the Allies prototyped this walker from spare tank parts, however they quickly abandoned the concept when they discovered that, cunningly, the enemy had planned for such an eventuality, by building their country on a series of gentle hills.
WAD to move, S to enter aiming mode. Cannon is disarmed when not in aiming mode.
(if anyone knows how to fix the bouncing around a comment would be much appreciated)
