Rumble Fighter is a free-to-play, 3D, massively multi-player, online casual fighting game. Players can battle each other individually or in teams, or take on a more ‘arcade’ mode fighting CPU enemies. There are a number of fighting styles to choose from, activated with ‘Sacred Scrolls’, which are upgrade-able. Players can also transform in battle, changing their appearance and abilities, utilizing ‘Exo Cores’. Players can fully customize their appearance to become truly unique, which also affects abilities. Upgrades, clothing, items, can be purchased with either ‘Carats’, which are earned, or ‘Astros’, which is OGPlanet’s currency. As per usual OGPlanet fashion, Rumble Fighter is free-to-play for as long as you desire.
