This is an app that offers fights in its rawest form. To get started you may choose one of 14 muscle-bound guys and one of eleven settings.
The game features four levels of difficulty. At the beginning you win by wildly pounding on the keyboard. Later on some special attacks are needed, which you accomplish via complex key combinations. You might want to practice those in the Dojo or Sparring Mode.
You are fighting either against the computer or with the multiplayer via Bluetooth connection against friends and acquaintances.
