The game uses sprites instead of 3D models. While the game looks different from Renegade, a version of the arcade game with new Kunio-Kun graphics is on the cartridge. Hot Blooded Tough Guy Kunio-Kun Special also has a brand new story mode with RPG-like character growth elements. I suppose that makes this game mode more like River City Ransom.
Hot Blooded Tough Guy Kunio-Kun Special also has a multiplayer mission mode, four player battle royal, and a gallery mode covering the entire series.
Why remake Renegade now? It’s the 25th anniversary of the Kunio-Kun series. Hot Blooded Tough Guy Kunio-Kun is slated for release later this year in Japan.
