Knockout League is a single-player arcade boxing game developed by Grab and released in 2017 for Oculus VR, Meta Quest 2, PlayStation 4, PC via SteamVR, and Oculus Quest. Designed specifically for virtual reality, the game uses 1:1 head and hand tracking, meaning physical movement drives both dodging and striking. Players work through a roster of eccentric opponents — including a mad scientist and an octopus — each with a distinct fighting style and unique attack patterns, such as flaming uppercuts and tentacle swipes. Between bouts, training drills like focus mitts and Reflex Alley provide additional physical challenges and help develop reaction skills. The overall objective is to defeat every fighter in the league and claim the championship title. The game's mechanics are designed to deliver an intense physical workout alongside its arcade-style combat progression.
