Two-personed with my brother. AND HE'S TERRIBLE! It's fine that he hasn't played the game before, he knows the controls just fine. But he never listens to me. I say don't leave the help room, just cover the door while I fix all these windows. He goes into the main room on the far side, gets incapacitated, then gets me killed when I revived him. Oh, but if that wasn't enough, when he's trying to clear the zombies when I'm lying on the floor, I tell him not to spin in circles. What does he do? He spins in circles. Now zombies are all around him, attacking him from all sides. Game over. He quit and I played it by myself, and I get just as far alone (lv 6) as I do with him (that was yesterday). Today, me made it to lv 9, but only because I got a raygun (against my luck) from the box. I will never trust him to guard my back as long as he's playing. I also explained to him how to get in the grenade glitch spot because he grabbed a flamethrower. He was doing fine, but then he decided to get out of that spot because he thought the barrier wasn't far enough away. Guess what? I had told him not to and now he's got a mob of zombies around him and his only good gun is a flamethrower.
Why can't I have a good brother that realizes that he isn't right all the time?
