As of right now 24+goro+4DLC=29. Im hoping with this new factions that they will continue to add more kharacters through DLC. Alot of great kharacters r gonna miss the cut on this game. I can see this game being around a long time with so much kontent in this game,id like to see them continue to build on it. Kharacters like Fujin,Reiko,Tanya,Havik,Bo Rai Cho,Frost,Lei Mi n even Hotaru should get a reboot
