...is it's dreaded belly bounce attack. It stops you right in your tracks and the monster then proceeds to grab you while you're stunned. It doesn't happen to me often, but it irritates the **** out of me when it does!
Maybe its because I was watching Batman Begins but . . . "You never did learn to mind your surroundings."
sorry, had to say it. lol yeah those things are annoying though. I always find, especially in campaign mode, I have an over abundance of pulse grenades, just use one to stun then light the Skagdead up.
