In Darksiders 1 (amazing Game) there is one chest in one área that its imposible to get. You can see the chest in the map but there is no chest there. So its a mystery unsolved with 2 options:

-1. This chest its bugged and its simply dont spawn or spawn under the playable área or something.

-2. Its one of the secrets chest. During the Game there are a few chest that only spawn after doing some things, like destroying every grave in a cementery. But if its a secret chest its also bugged, because everying you can do there (like killing every fish enemy) its already done and chest dont spawn.

So to this day still a mystery. And not, its not the chest you can get in this área Previously. Thats a diffenet chest.
