Isle

Isle was a map that was released in the beginning of the game and was removed just after the game came out of alpha. It was considered the "meta" map as it had a twisting path that looped around at the end and then back to the beginning then straight to the end. It was a small map in size and towers like the sniper could easily hit the entire map without upgrades. It was probably removed due to how easy it was to win and how it was the only map that was really played due to how easy it is.

The picture to the side is of the Isle map. (Notice the 2 loops.)
