As an introduction to Dead Rising 2, Case Zero gives you a look at the new characters Chuck and Katey. The story actually takes place three full years before the Dead Rising 2 story, so Katey whom is 4, will then be 7. This game is a really easy arcade game you can complete in one or two sittings. It's priced a 400 MS Points. There is no difficulty setting and three save files. Like the first Dead Rising, if you die or quit, you have the option of restarting the story with your stats.
Step 1: Getting 1000 Kills
The first thing you want to do is get your 1000 zombie kills. If you attempt it while trying to do everything else in the game, you will be extremely stressed for time. Start the game up and continue until you get the cart with the main bike frame in it. This is within 5-10 minutes of the game's start. Now just run around town (holding ) with the cart running over zombies. Within 20-30 minutes you should have all 1000 kills and a ton of experience (should be almost or to level 3). Now you can hit and restart your playthrough with all of your gained experience.
Step 2: Spending $100,000 at Pawnshop
Go ahead and start up a regular playthrough. Once you get your $30,000 (check description for "Small Town, Deep Pockets" in the guide), save your game. Either make a save in slot 2 as well, or continue on remembering to get your achievement and then quit. Keep going back and forth from the casino to the safehouse gaining a good amount of money each run. Buy the moose head to run faster by holding down . Keep spending your money until you get the achievement.
Step 3: Getting All Weapon Combos Created
From the previous step, you may continue your game and grab all of the weapon combinations, or start a new game on a different save and run through really quick to grab them all. You can get all combinations within a shot route through the town, taking up to only 15 minutes. There are only 9 of them total. See the achievement details for the route, checklist, and video.
Step 4: Play Prelude - All Survivors and Unlocked Doors
Now it's time to play through the game gaining the rest of the achievements. You will have plenty of time to do everything you need, and will only need to complete the story once provided you followed the previous 3 steps. You now just have to find all the parts, survivors, unlock the doors, and defeat Jed. Follow the guide for specific details on where everything is, and make sure you buy a 2nd Zombrex from the pawnshop so you have the extra one for Katey. Make sure you pick it up from the floor, or you'll have to buy a new one as the items will vanish when you head through the safehouse.
You should now have all of the achievements in the game, most likely in one easy sitting. This game's stats will carry over (top level being 5) to the Dead Rising 2 game. You should also have a good understanding of the game mechanics and how things work. Feel free to explore more on a continued playthrough with your stats maxed for fun.
