Watchmen The End is Nigh

To perform a Counter Attack, press RB + X simultaneously. When the enemy is about to hit you press it, or just go up to him and mash it. You might roll around but once he attacks you'll go into the little animation of your character straight up kicking some butt. (It will also clearly flash "Counter Attack" in white and red while displaying RB + X). Look up my guide for unlocking the "Untouchable" achievement in this game. If you did that method, you should almost have it. Don't worry though, you shouldn't feel rushed, because this, along with several other achievements in this game will eventually come during your multiple playthroughs of this game.
