A is move left, D is move right. W is cape stun, S is counter, space bar is jump. If you are touching a foe, you are fighting them, so you both take damage UNLESS they are stunned or countered in which case you will not take damage (if you counter, they will also take extra damage). Beware, you have a limited supply of stamina, and if you are too tired, you can't jump, cape stun or counter. You will heal over time IF you have plenty of stamina (stamina regenerates over time, but jumping, stunning and countering lower it, as do some foes). Please note: This game has no end as of yet, when you get to the final stage, you keep fighting until you die.
Batman was tipped off about a gathering of villains at an old boxing stadium, as he entered the dark building, the lights blared on and bars appeared over all the exits. Suddenly, Zasz's voice could be heard over the loud speaker and a figure approached from the other side of the ring. "This is not going to be pretty." Batman growled as he prepared for the fight of his life.
