Tremor is a miniature, mobile version of a Buzzsaw. It basically is a very fast shooting artillery vehicle with an incredible range that can compete with longest-range defenses like Annihilator. It shoots along parabola, which makes it able to target units on the other side of walls and hilltops. Due to its high costs it has a situational usage. Useful on maps with many natural barriers separating different sections and bases. It shoots with a pretty spread aiming hence it damages units in a huge area at once literally creating a ‘rain of plasma’.
