yea he is but we found out that after the first time he comes, he is incredibly fast and u cant get away from him. what we did was let him take one of our guns and then wen he would go after the second guy, he'd be alot slower (unless u run with an lmg or shotty). the 2nd guy would run around in circles in the 2nd room (computer room) and he cant catch u, while the other shoots him. its quite easy, but we got caught out cause wen he came we were at the top level and couldnt get to the middle and he got us both.
