whwn someone disconnects and then connects again, the zombies stop respawning so you cant finish the round, this is the glitch that mo12345 was talking about, + so igor can see
soz if anyone has already posted something like this but after you buy the car from derbin, go to the garage and the zacks only come from one way so if you stockpile ammo you can stack up the points, i got the barret 50. that way (P.S + if this helped and you LOVE THIS GAME)
