This is counted across Attitude Mode, Universe Mode and Exhibition matches. Requires 2 super-heavyweights (for eg. Big Show and Mark Henry). In the match make up a finisher (or assign a finisher from the start to your superstar). Throw your opponent into the turnbuckle, you should see a prompt to hit the button but with OMG written across it. Just press the button, your superstar will perform a ring breaking superflex, awarding you the win by KO and the achievement. Note no difficulty criteria here.
