Introduction:
Case West picks up where Dead Rising 2 left off. This time around though you have an old friend helping you out, Frank West himself. You do not need Dead Rising 2 to play this game because it is a standalone XBLA game. The achievements are pretty straight forward and you will unlock most of them with relative ease. The easiest way to get all of the achievements in the game is to do one full playthrough and then do partial playthroughs to mop up the rest.
Step 1: Full playthrough
In this playthrough you should aim to obtain all of the achievements except for Petty Vandal, Professional Photography, and Double the Fun because it's easier to obtain these on a different playthrough. While playing through the story pay attention to the survivor guide in the achievement guide to get Savior. You have to save all of the survivors in one playthrough to get the achievement which isn't that hard.
Killing 1000 zombies is very quick to do and you can do it while waiting for a case to start. The fastest way to get kills is to run zombies over with the vehicles in the loading bay. When both vehicles are destroyed go in and out of the shipping office to make them respawn.
There are seven new combo weapons to make in Case West. Most of the items needed to create the weapons are really common and shouldn't be a problem to find. You have to create all seven of them yourself for the achievement. You only have to create a weapon once for it to count on all playthroughs. Check the Handy Man achievement in the achievement guide for more information on the combo weapons.
You should get Phenotrans Sabotage, Phenotrans Nuisance, and Phenotrans Bubble Burster by simply playing through the story. The easiest way to kill Hazard units is to use their own weapons against them. If you don't reach level 50 in this playthrough you should be able to reach it while destroying cameras and taking pictures of the PP stickers in the next playthrough.
Step 2: PP stickers and destroying camera's
After completing the game, restart the story and keep your current level. You should get to level 50 in this playthrough if you haven't already done so. Follow the videos in the achievement guide to destroy the camera's and take pictures of the PP stickers. After destroying the camera's and taking pictures of the PP stickers you will unlock Petty Vandal and Professional Photography.
Step 3: Co-op playthrough
To get Double the Fun all you have to do is defeat the psycho in case 3-3 while playing with a co-op partner. To find a co-op partner use this thread here. To make it easier for your partner, make a save after finishing Case 3-2. Then all you have to do is reload this save and defeat the boss with your partner and you will both get the achievement.
Conclusion
This game is short but sweet and the achievements are incredibly easy to obtain. The only slightly challenging part of the game is the final boss. To defeat him easily either defeat him in co-op mode or let AI frank do all the work since he cannot die. The best weapon to use against him is the AR machine gun or the weapon the Hazard units use. Good luck and happy zombie killing.
