Be additional mindful with the blowing up fat zombies. When you kill them, shoot them initially every time as they will kill you too if they are too close to you. For the other zombies, start with the ones that are closest to assaulting you and work your way back. Or if there is one particular zombie that you are expected to go for to complete the round (a boss zombie), go for that a person for a fast end to the round.
