It seems to consist of an isolated desert-like environment. A UFO appears to have crashed with an alien sign next to it. 3 flowers can be in view. Along the top-left side there is a fence, saying "Keep Out!", which parts of the wire appear to be broken. There are bits of rocks lying everywhere.
A Tack Shooter can still be useful where lots of sections meet. Placing an Ice Tower where the sections meet can also be useful.
Because of the straight lines of track here, it is recommended to use piercing projectiles such as the Ninja Monkey. The Juggernaut and Spike-O-Pult with target set to last is recommended to be placed along the top horizontal line, where two lines have a gap, but form a straight line.
