I'll never forget. I was patrolling the forgotten shore and decided to lurk around the grotto. On the way there I see a vandal. I lob a grenade and notice it didn't do shit to him. Intrigued, I head over and punch him, nothing. The battle begins. Emptied my ghorn, sniper and primary and a super, finally killed him. Sat there dazed and confused. Like Wtf just happened?!!
