Small Digger

Much like Cole's Earth Driller, this machine can flatten out terrain in a more gentle way than the terrain editor. It will make small square tunnels when dug below it's roof. Unlike the Steamroller, it's orange beacon does not get stuck on terrain. In the release version of the game, sometimes while digging a tunnel the digger would glitch and make really steep declines into the earth. Overall, it make very neat tunnels.
