DOOM - House of Pain

Access the Map

After grabbing the Yellow Skull and defeating the ensuing attack, approach the exit portal and search the nook on the right to find the lever. Then return to the previous room, where you found the Argent Cell, to discover a new opening on the right wall. Step inside to unlock the map.

Map Strategy

Three keys must be collected to exit House of Pain. The left and right paths lead to resources. Head up the middle until you reach two round pits. Give them a wide berth to avoid triggering them. Throw the left and middle switches to raise the platforms in the pits. Quickly grab the resources. The right switch opens the path to the right. The blue key is in the far corridor. Enter the nearby blue door and follow the path ahead until you reach two pillars with skull switches. Two switches on the right open two doors to the right, one of which holds the yellow key. Two on the left pillar open the left doors. Find the red key behind one and the red door behind the other. Continue to the exit.
