How Hell is Us Mysteries Work

Hell is Us Mysteries are another class of side quest, albeit with a twist; these side quests often (but not always) lead to caches of useful items that will aid you in your adventure. A Mystery can be a simple as a locked door or as complex as a multi-stage quest that will take you to several Locations on the map.

Unlike Good Deeds, Mysteries cannot be failed as far as we can tell. Some of the Mysteries, however, are a little more difficult to solve on your own.

Read on for a list of all of the Mysteries we've found, where to find them, and how to solve them!
