A new physics-driven hit reaction and knockout system delivers more visceral KOs than before. Every knockout is now unique. Simultaneous two-fighter interaction brings the ground game to life with greater responsiveness and variety. Surprise your opponent with a flying armbar from the clinch, or with a quick transition from a knee bar to a heel hook. Standing submissions and submission chaining have been added. Add an improved blocking and parrying system to the mix and you have new tools to fend off your opponent’s most devastating attacks.
