Cobra Kai: The Karate Kid Saga Continues

Kyler is the final boss of the Smitty's Diner level. This is very similar to the Cobratribes achievement (knock him onto his stomach, stand over his torso area, press then mash ) with two exceptions. First, you don't have to finish Kyler off, you just need one hit for this to count. Second, as a boss, Kyler will get up faster than your garden variety enemy, so you'll need to almost need to be right on top of him once he's down to take advantage. I found that when successfully parrying his charged attack (he'll glow red beforehand, counter by hitting ) the resulting throw left him backside up.

There's no option from the Pause menu to restart from checkpoint, so if you find you're getting too close to defeating Kyler, allow all your players to be knocked out. You'll get the option to Replay from Checkpoint, which should start you again immediately before the boss fight.
