There are 40 biozahards to burn, ten in each district:
- South Almuda
- Ingleton
- Central City
- Sunset Hills
These collectibles become available after you take Nelson to Annie's Old Fashioned XXX, and you have to explore while he works. There is a box of slagshots nearby, so be sure to grab a handful to burn the piles.
On the map, they appear as a yellow circle within a circle. In the game world, they'll have a green flare marking them.
timotei1982 created a map, which can be seen in his solution:
Solution for Ashes to Ashes In Dead Rising 3From what I've read here and on XBA, there are two potential glitches that can happen.
1. A biohzard pile might not be marked on the map. Fortunately, if you know where it is, you can still get it.
For me, it was in the top north-west corner of Ingleton, behind a house. The following piles seem not to appear on the map for many players, so if you're missing one, check these locations:
- NW Ingleton (behind the house)
- N Almuda (in front the box truck behind the safehouse)
- Middle of South Almuda (very obvious on a sidewalk - in front of the fabric outlet)
- N Almuda (outside the Bus Depot)
- N Almuda (on a corner to the left of the entrance of the tunnel to Ingleton)2. The counter stops counting biohazards. For example, you get #37, then find #38, but the game counts it as #37 again.
This is the worst of the two glitches, as replaying the DLC won't fix the count. The only fix for this is to start a brand new save file. See below for details.YOU MIGHT LOSE YOUR SAVE DATA. PERFORM THIS AT YOUR OWN RISK.1. Press the "start" button while highlighting the DR3 tile on the dashboard, and choose "Manage Game"
2. Move all the way to the right, and select your save data.
Choose "Delete from Console." Choosing"Delete Everywhere" would delete both your console and cloud saves, you want to restore your cloud save later.3. Disconnect the One from the internet (turn off wifi). This isn't really necessary, but it helps prevent you from accidentally doing something you don't want to do yet. If you skip this step, jump to Step 9, then back to Step 4.
4. Start up the game, and begin a brand new game for DLC 4, all the way back at Level 1.
5. Slog through the DLC to get to the point where the biohazards appear. This will probably take about an hour at low levels.
6. Burn all of them again, and make sure the counter does not stop counting this time.
7. Stop short of 40, save the game and quit.
8. Reconnect to wifi and restart the game.
9. At the main menu, you'll be told that the save on your console and the save in the cloud are out of sync, It will give the option to sync with either save, or not to sync.
Choose "Stop syncing" (IMPORTANT!) Choosing this option retains your new console save, and your old (presumably level 50) cloud save.10. Resume the game, and burn the remaining bodies.
11. Achievement unlocked.
12. Quit game once more.
13. Reload the game, and this time, choose to "Sync with Cloud" since you want to restore your cloud save.
14. Destroy DR3 disc. (Optional)
Thanks to mcnichoj for originally posting the workaround on XBA.
