Welcome to Dead rising 2: Off The Record, a spin-off from the Dead Rising 2 story with Frank West as the main protagonist. Once again the setting is Fortune city, but with a new area and a few new little places. You will need two story playthroughs to level up & to get specific achievements as well as completing challenges in sandbox in both single-player and co-op. This guide will guide you through each step needed to get all the achievements. Click here for help on the gameplay and making things easier & more fun.
Step 1: Story Mode
Any story or survivor related achievements can be unlocked in single player or co-op. So start story mode in either/or and get to grips with the game, make combo weapons and complete the story & try to save all the survivors needed for the achievements - this will net you the story & survivor related achievements. This will level you up and make you stronger, making the game much easier. Once you're a high enough level you can start a second story playthrough and go straight for the Purewal Memorial Cup & Alpha Vs. Omega achievements, this means consuming no meat, dairy or alcohol & keeping Denyce with you until Case 7-2. See the individual Achievements for further detail. Once you have that done you can start partial playthroughs to get any miscellaneous story or survivor related achievements you missed.
Step 2: Sandbox
This is where you’ll want to get your PP sticker achievements as there is no time limit. You can also go for any miscellaneous zombie or photo related achievements here. However, mainly you will be working on completing every challenge to Gold, see the 'Challenge Domination' achievement for a full in-depth guide on how to get gold on all challenges.
Step 3: Co-op
Now you will want to get a co-op partner & get the 5 co-op achievements. If you need a co-op partner click here. You will need to complete all co-op challenges in sandbox to gold, 'See the Even More Help From My Friends' achievement for further detail. The other co-op challenges are simple and can be done in co-op or single-player
Step 4: Six Digits
Complete all other achievements before going for this as it will make it less of a grind. Once you have, go into sandbox mode and keep getting kills. For the fastest way possible to get the achievement see the 'Six Digits?!?' achievement.
Dead rising 2: Off The Record is much easier than its predecessor and will be fun for the most part, but it will take that extra push to be willing to grind for the final 100,000 kills.
