Karate Master 2 - Spartan X is sort of a rhythm-action game, where youre presented with a bar of rectangles, and an indicator that goes across it and back constantly. Youre fighting an enemy, and do damage by hitting the yellow and green rectangles, the green ones doing critical damage. The red blocks slide from right to left, and if they reach the left part of the bar, then you take damage.
Try to hit exactly to creat combos and become hero!
