Overview
Easiest and fastest (imo) way to unlock the Zombie Genocider achievement and the real mega buster while leveling up Frank!
Getting Ready
First of all, you need to learn this route (maintenance tunnel) it will take you around 10 laps to fully master it
Also, i recommend to beat the game at least once and/or know where most of the items are located (general knowledge of the game)
*Attention*
Some people reported that their game crashed while having a few thousands of zombie kills, so its preferable to save every now and then, the easiest way, is to grab the key that is located in the maintenance room (located in the middle of the map, in the tip of the pen1s looking road). Just grab it, open the map and look for the nearest save spot, be careful tho, theres a lot of zombies inside that room, thats why its recommended to grab the drinks that i will explain later in the guide.
Lets Go
1.- Start a new 72 hour mode game
2.- Skip the helicopter intro etc
3.- When you are finally in the safe room, dont go to brad, let him fight carlito forever (no matter how much time passes, the case will never be over)
*Optional* Get the Horror novel 1 and 2 magazines in The Sinister Read at Entrance Plaza and Bachman Bookporium at Paradise Plaza in case you want some extra points and need to level up.
4.- Pick up some wine or orange juice in case your car gets wrecked and you have to walk to the next car (which eventually will happen)
*** If you decide to go for the wine and the magazine, your only way to go there is from the court food, the carlito fight will trigger but dont worry, just grab the wine and go all the way for the magazine and leave, the scoop will start draining but youll never fail it***
5.- Now go to the Leisure park parking lot and get in the red car
6.- Go inside and follow the route (Try avoiding the zombies with the big propane tanks, its not possible to avoid them all but try to as many as you can)
7.- Instead of turning right first, i killed the zombies in the parking lot with the car (easy zombie kills)
8.- Repeat this over and over again until you are done. (Took me around 4 hours of non stop driving, each lap nets you around 1000 kills, that means youll be doing around 60 laps)
(I saved when i had like 28k kills just in case, and on my way back i killed the convicts with a bat, which is pretty easy once you know how to kill them and took their jeep, which lasts around 2 laps, or if you dont want to waste a few minutes, just go to the room i mentioned at the beginning of the guide and save)
9.- Once you are done, (DONT QUIT, BEAT THE GAME AND GET THE ACHIEVEMENT OR YOU WONT GET THE REAL MEGA BUSTER) go back to the helipad (upstair in the safe room) and wait till the chopper comes pick you up (day 22, 12pm in game time) or save some survivors for massive xp, or keep killing zombies.
10.- Save, and youll get the real mega buster unlock prompt
11.- Start any mode, and the mega buster will be waiting for you next to the other unlocked costumes in the safe room.
Done!
And thats it, following this guide will help you get, a *maybe* level 50 Frank West, the real mega buster which makes everything easier and the zombie genocider achievement. Any questions dont hesitate to post them in the comment section.
