NoTerrainTankTrack is a performance machine. Normally a tanktrack is all terrain, this one is no terrain. it will not move from its place. when it tries to move it will only destroy itself. It is also an investment of a lot of time (12 hours straight of drilling holes in glass, and in reality likely 2 or 3 times more) into something that will never “work” an other way than destroying all the work.
