Lost Saga is a brawler MMORPG with different heroes to play as like a Martial Artist, Cowboy, Ninja, and Robin Hood look-a-like. Iori Yagami from The King of Fighters is also on the Lost Saga list as a premium character.
WeMade Entertainment licensed Iori from SNK Playmore and he’s just one of the fighting game cameos in Lost Saga. Hazama, Jin, and Ragna from BlazBlue plus Sol Badguy and May from Guilty Gear are in international versions of the game. If you want to check out Lost Saga here’s a link to download the client. It looks like wacky characters like the Mafia Boss and American Football Running Back aren’t in the US version yet.
