The returning Rage system sees a makeover with "Heat Smash." The scrapped "Screw" property is replaced by "Tornado," extending juggle combos. Tekken 8 aims for a cinematic feel, with stage destruction, new character models, and Unreal Engine 5 power. The online mode includes "Arcade Quest," offering avatar customization with "Fight Money."
