Audio problem: The Choking Grounds: After being freed, the Gatekeeper will walk down the road and then leap up onto a higher area and proceed to walk behind a building to go away. Each step he takes is very loud as he's a giant rock creature on a paved road. But the moment he passes behind the building, the loud sounds of his steps stop where as you should still be able to hear him walking a way for a good distance. If you're standing in the right spot, you can even see him just suddenly despawn behind that building.
Bug: The Ashlands: There is a hole in the area where the Abysmal Riders spawn. This hole is like a well with wooden structures around it and sticking out towards the sand. With the clunky controls of the game for when riding on Ruin (your horse), it's easy for you to get stuck on this structure. If you jump on Ruin while moving towards it, you can get stuck and Ruin will just be there running in place on this board until you get off him.

Trivia: The Apocalypse/Mayhem: During the cut scene where you see Abaddon and before you fight Straga, there is a moment when a Minion Demon tackles an Angel out of the sky next to a billboard on a building. If you look closely at that sign, there are various names on it. These names are people who are part of the Darksiders' development team. Names including John Tran, Howard Tang, Bri Thatcher, Nick Southam, Chris Doerr, Jeremy Robins, Pedro Seminario, and more.
