How to Earn the Zombie Genocide Achievement in Dead Rising

Probably one of the game's most difficult achievements, Zombie Genocide requires you to kill a zombie for every resident in Willamette, Colorado. That amounts to precisely 56,594 zombies. Doing this requires a sacrifice of sanity, as it involves driving cars through the Maintenance Tunnels for most of the game. So let's do it!

Challenging

Instructions

1. Bring some OJ, hunting knives and a few pistols. Both of them can be found in Paradise Plaza.

2. Head to the Maintenance Tunnels as soon as possible. Getting this achievement will take almost all of your 72 hours.

3. Leave Paradise Plaza and head into Leisure Park. Go straight, towards North Plaza.

4. Take a left before you hit the stairs and look for a big hole in the wall of the park. This leads to the Maintenance Tunnels.

5. Head through the zombies and find the red car. Drive this into the tunnels and start plowing down zombies.

6. Find the truck at the far north end of the tunnels. The truck is the best zombie killer. It drives the slowest, but does the most damage before it breaks.

7. Find the white car at the far eastern end of the tunnels. This car is the next best zombie killer. It is more damaging than the red car but goes faster than the van.

8. Drive slowly. Hitting anything will reduce the life of your vehicle.

9. Keep an eye out for zombies with propane tanks. Hitting these will create an explosion.

10. Drive your cars around until they break, then head to the next location for another car.

11. Save your game every 5,000 kills.

12. Find the Maintenance Supply Room. It is in the center of the tunnels, at the end of a short south-facing passage. From the start of the tunnels, take a right, then a left and then another right. Be sure to grab the submachine gun and the sledgehammers in room. Good luck!
