Mutant Storm Empire -- World 1 Level 3 (Black Belt)
Best way to score big points is to use the orange "worm" combo in room 3, as shown in the video. Also I show how easy it is to beat this level on Black Belt.
There are two other ways to gain big points. One I show in room 2. The other is to start on Green Belt and use the three turrets combo in room 2.
