Convicts

The Convicts are three escaped inmates that ride around in a stolen military Humvee with a mounted high-caliber machine gun. They occupy Leisure Park, attacking survivors and zombies alike. You are able to take their car when they are dead, earning an achievement and a new outfit. You are also able to take the gun off the back of their car. They will respawn at midnight in 72 hour mode.

Tactics
The best way to get away is to ride a skateboard or use a shopping cart to where you need to go. If you plan to fight them early on, visit the hunting shack early on and take a sniper rifle. It also helps to learn the move zombie ride. Go to one of the picnic shelters and zombie ride to the top. They also tend to glitch out and get stuck if your underneath the picnic shelters. Snipe the gunner first, then the driver and the passenger.

Another easy way is ease them close with an object such as a tree behind you and move when they get close enough to not be able to turn away. After they hit, it will take them a minute to get out. In this time, killing the gunner is priority. After that, the Passenger or Driver can die in any order, but if you kill the driver, the passenger will become the driver. And easy weapon to do this with is an SMG (One can be found in Paradise Plaza by jumping the ledges with the teddy bear and boxes on it) since it is an auto-matic weapon and can deal damage fast.

The heavy machine gun found in the game is without a doubt one of the most powerful weapons in the game. The major downfall of it is that you cannot put it in your inventory. You can carry it and drop it when needed. Before you leave an area that causes a loading screen, be sure to have the HMG in your hands or else it will despawn and you will have to wait one day for the Convicts to respawn. Having the HMG makes most usually difficult boss fights easy in the begining. You can use this to clear the gunstore early and have access to gun supplies.
