Knockout 2: Wrath of the Karen is a free-to-play arcade rhythm boxing game developed by Exceptionull Games for Android devices. In this game, you play as a boxer who is on a mission to take revenge on everyone who has ever wronged you. The game is set in a world where all disagreements are solved through boxing, and you have to tour the nation and the world to pick apart each opponent's fighting style.

The game features classic arcade boxing action with tight timing and even tighter controls in the style of Punch-Out!! You can customize your boxer and enter the ring to fight against opponents ranging from Karens to Cat Ladies. The single-player story is every bit as comedically scathing as the first game, and the game mechanics have been refined to build upon the risk and reward boxing style of the first game. The game also has full keyboard and gamepad support, making it easy to play.
