This map is themed around the idea of earth consuming metal over time, similar to a weed consuming pavement.
The Sense Powerup is available if head to head (game type provided) is played on this map.
It's best utilized with head to head, however, it's perfectly compatible with 4 player Free-for-all, and team doubles as is the standard with my maps.
Enjoy!
(Update 1.8: Fixed an Issue with the overshield it can be picked up now)
