Walkthrough

Map of Io 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. Walking over the north side of the starting red square reveals an alcove to the south with a shotgun, The back wall of this alcove is a secret door leading to a corridor containing health bonuses and a megaarmor. Collecting the megaarmor teleports you back to the north of the corridor. (sector 37)
2. The far south-east of the level contains four pits each with a teleporter. The north-western one has a secret door in part of the curved section of wall leading to an imp, a demon (easy and medium skills) or a spectre (hard skill), six health bonuses, and a soul sphere. (sector 68)
3. The north wall of #2 is a secret door leading to an energy cell pack and a switch. The switch lowers walls directly north of the start (through the door revealed by walking across the south side of the starting red square) revealing an energy cell pack and a BFG9000. However, in order to collect these items it is necessary to have lowered the corner walls of their rooms by pressing them before the switch in this secret is pressed, otherwise the walls will not lower fully. (sector 110)
