Hello, first time playing Doom the dark ages. I’m playing through chapter 6 and see that both these chests are locked. I know the second one most likely involves flipping a switch that I haven’t found to open the gate, but the first one has me at a complete loss. Is there a particular enemy I have to kill or something? I’ve cleared out the entire section of the map of demons where the chest with the barrier is found, yet it still hasn’t opened. Any hints would be greatly appreciated!
