Walkthrough

Map of Chronos Anomaly

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. In the base area at the east side, go to the northernmost room with the mancubus. Use the picture here and the switch behind it, opening a window to the west. Jump out the window to get a soul sphere. (sector 269)
2. In the southeast area, at the south ledge with the plasma gun, enter the southeast closet and use the light gray brick to find a hidden switch. This will reveal a soul sphere from the west door. (sector 1097)
3. In the northwest base area, enter the room with the arachnotron and flip the switch to open the bars to the northeast door. To open that door, go southeast of the central room and use the access switch on the east side. Go north and open the door to get health bonuses and a megaarmor. (sector 1775)
