Deadly Arts (known in Europe and Japan as G.A.S.P!! Fighters' NEXTream - Generation of Arts, Speed, and Power) is a 3D fighting game developed by KCE Osaka and published by Konami for the Nintendo 64 on March 26, 1998 (in Japan), September 1, 1998 (in Europe), and October 7, 1998 (in North America).
The game includes 10 total playable characters, two of which are unlockable bosses (which are both unlocked by doing the Konami Code in the title screen, both normally and in reverse). Additional characters can be created with the Create-a-Fighter mode, but are only playable in other modes once they learn enough moves for their custom movelist.
All characters have a different "nameplate" for each version of the game, with the North American version having a simple plate and "lifebar name" font. The Japanese version is the only one with full voice acting.
