Statues - You will need to have pack-a-punch. Wherever the pack-a-punch is, go to it. (Do this next part in the order of your pack-a-punches.) If it's at the Iceberg then the statue is found to the left of the machine. If it’s at the Boathouse the statue is found to the right. If it’s at the Beach it is directly behind the machine. If it’s at Sunken Path the statue is directly behind the machine. If it’s at the Lagoon it is located behind the machine.
5th Perk - Once you have all the statues go to the beach and place them in the little altar with candles. Once placed the next round will have lots of electric zombies which you will now have to kill. Once they are gone there will be the 5th perk back at the altar.
