So this game called Rumble Fighter (Korean name is Gem Fighter), is 3D fighting game where you team up with a maximum of 4 other people and fight a different four other team, or you can just go an 8 battle FFA. There are currently 5 classes you can choose from; Striker (Str), Soul Fighter (Spd, Agi), Elementist (Magic), Alchemist (Def), Shaman (???), and Android (A little bit of all. Unlock at level 20).
To fight in the game, it uses realitic martial arts scrolls you can purchase with real money, or money you win in the game, such as boxing, karate, drunken master, pro wresling, and a lot more.
You also use things called exocores which are the things that require your MP usage. Exocores usually are classified from what character you are (Striker - Power based Exocores, Soul Fighter - Speed exocores, etc) There are also Exocores that everyone can use.
All in all, it's a pretty fun game, you should try it out. And if you have, then you can talk about RF related things in this forum.
