Map of Deep Space Observatory

Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.

Secrets

1. At the yellow key, look north and shoot the green button. Head southeast to teleport to find energy cell packs and a plasma gun. (sector 113)
2. In the yellow key area, raise three pillars to the south, then get on the first one and go through the south wall to collect a berserk pack. (sector 139)
3. Enter the lava at the southwest side and get to the middle of the building from the north end, where you can find a soul sphere. (sector 153)
4. Drop to the floor southwest of the yellow key, then go to a thin wall northwest of the lift. There is a switch here. Flip it to lower a soul sphere to the west. (sector 301)
5. Go to the blue key and head west, using the button. Head west of the button to a teleporter which takes you to health bonuses and a megaarmor. (sector 415)
