Other points of interest[edit]


  1. From your starting point, take the only possible path into the big room with the red key on a pillar. Open the brown wall in the northwest corner of this room to reveal a secret room, but beware: as soon as you enter, an arch-vile (on UV and above) or a Hell knight (on HMP and below) will suddenly appear. Assuming you can defeat the enemy, collect your reward in form of a super shotgun, some shells, health bonuses, and a medikit. (sector 84)
