Out Of Control

If you only do one Scoop the entire game, you should do the one entitled Out Of Control. This is triggered at 9:00 PM on the first day, Sept 19th. You must visit Wonderland Plaza and defeat the evil clown Adam. After that, operate the amusement park ride's controls to stop the ride. You will then be introduced to another mall maintenance man who will then unlock the a door which will unlock a passage between Wonderland Plaza to Paradise Plaza. This is a huge time and life saver.

Paradise Plaza Secrets

It's good to know that early in the game you have access to two solid weapons here in the opening area. There is a Sub-Machinegun on top of the entrance of Cam's Camera Shop. Use the stairs to the right then jump off them and onto the ledge and shimmy along until you find this weapon of choice. Similarly, there is a Katana here as well. Head up to Colombian Roastmaster's on the second floor, jump out the "windows" to land on an awning below to and pick up one of the greatest melee weapons in the game.

Zombie Genocider

To get this achievement, you will need to kill 59,000 zombies during the normal 72 hour game mode in one play through. Meaning, it is the total number of zombies you've killed when while playing the game, you need to reach this number in one 72 hour mode.

You should probably only tackle this once you have beaten the game so that your Frank character is pretty beefed up. Start the game and play up to the Back-up for Brad case, it's really early on. Now grab some supplies. Stock up on some healthy food items like orange juice and some reliable weapons that can fend off hordes of zombies. Now make you way to the Maintenance Tunnels. This is the best area to rack up kill in. To get there, head out into the park and go to the north end and up through the alley. You will find a car which you should hop into and drive into the nearby tunnel entrance.

This is will be your home for this zombie killing spree so you should get to know it inside and out. Basically, you want to drive your car back and fourth down the tunnel taking out all the zombies in your way. There is a van down here too which makes for a great zombie killer as well. You should learn to time the life-spans of these vehicles so that you can hop out of the used one and into the new one before being stranded in the middle of thousands of zombies. When the van is nearing the end of its life, drive it out of the tunnel and hop into the car that re-spawns above ground and repeat.

This achievement will take some time and dedication. It is highly recommended that you save your game maybe every 5,000 zombies or so. You should also know that when you hit the target number of kills the achievement won't automatically be unlocked. You actually have to survive the 72 hour mode to get it. This can easily be done by simply returning to the starting helipad on the roof and waiting until the helicopter comes.
