Thanks for this! I knew I missed that big chest in the last platforming area and wanted to see if it was anything important. I'm glad to see it was just crafting stuff.
I thought the same, but it's not. You have to use the phone at the first camp to travel to the last camp. Then you can go backwards through the door and grab Quarantine Failure.
@Black_Sephiroth so are you just continuing with game +? Because I missed "Quarantine Failure" log and after defeating the boss it's blocked off. Lame.
