Once you unlock the secret room, you’ll be able to play Slough of Despair map from Doom 1. In Kadingir Sanctum mission, you’ll also unlock a new weapon Chaingun that deals major damage at a very high rate of fire. You’ll come across 24 collectible items like data logs, automaps, secrets, hidden rooms, elite guards, argent cells, field drones, and rune trials and each of them are needed in some way towards achievements / trophies. Don’t forget that if you reach the end of the mission you won’t be able to go back and collect some items. There is a huge number of well-hidden collectibles in this area, and some collectibles are quite confusing to find. Your main objective is to find a way back to Mars and stop the demons from absorbing your world. This is the first mission in the Hell dimension, so the surroundings change completely. Mission 6: Kadingir Sanctum is the sixth campaign mission in Doom 2016.
