The Citadel is pretty confusing to navigate. From what I understand this is one of the more hated maps in the game thanks to all the cryptic stuff you have to do just to find your way around, and it certainly isn’t my favorite map. I’m pretty sure some of the secrets are mandatory which is very dumb! My advice? Do what I did and just follow a guide!
There are also some tricky fights here, namely the imp ambush in the secret red building. There are so many imps that you’re likely to run out of ammo, which happened to me on one attempt.
Anyway, UV-Maxed it so I wouldn’t have to revisit it any time soon. I had to backtrack a few times in order to kill all of the enemies. I visited the red building twice so I could get the rocket launcher and use it to beat said imp ambush as well as the pack of spectres outside.
