Walkthrough

 * Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count towards the end-of-level tally. Note that the mentioned sectors are those where the player practically triggers the secrets. The sectors themselves do not always have functions that affect the secret tally.

Secrets

 * 1) Sector 721: As with the original level, the north-east corner of the south room and south-west corner of the east room are lifts which lead to a nukage-filled area, with a chaingun, bullets and two stimpacks on an island.
 * 2) Sector 2366: On the central hub, go to the east room. Inside it, there is a bunch of crates to the north-west. Pass through the small ones and get a super shotgun and a box of shells.
 * 3) Sector 4246: Just when you get to the great outdoor area near the exit, turn right (or to the north in the automap). You will see a UAC logo above you to the right. Press on it to open a secret ledge containing a supercharge. The floor in front of the ledge has a narrow elevated surface that goes along the entire side of the building. The surface's level is just high enough for you to reach the narrow platform between the floor and the ledge where the soul sphere is kept. Jump first onto the platform and from there onto the ledge.
