Rumble Fighter is a free-to-play fighting MMO game with real mixed martial arts and fast-paced beat-em-up action. A long time ago, the Dark Lord broke the peace treaty with the Gods, and commanded his dark forces to conquer the unsuspecting Rumble Fighter world. The vulnerable Rumble Fighter world was almost immediately taken over by the dark forces. When all hope was lost, a miracle happened. Powerful heroes chosen by the Gods arrived to defend against the dark forces.
