Secrets[edit]
- Go through the first door and turn right. Near the first armor bonus you reach are two alcoves. Pressing the western one opens up a secret door opposite leading to a passage with a shotgun guy and two health bonuses (on medium and hard skills only), and a megaarmor which lies on a teleporter to the south-east area. Both the passage to the teleporter and the teleporter itself count as secrets. (sector 27)
- See #1. It is not possible to receive credit for this secret as the player teleports before stepping on the sector. (sector 28)
- From the blue key, head east then south. Continue through a fake wall, at the end of which is a soul sphere. (sector 118)
- Heading north from the blue key area, there are two passages to the west. Between them is a fake wall, through which is a partial invisibility and a lift leading up to a berserk. (sector 122)
- The room with the teleporters leading to the red key area has a secret door on its north wall leading via a second door and a lift to the yellow key and a box of shells. Both the sector between the doors and the yellow key sector count as secrets. (sector 256)
- See #5. (sector 179)
- Head north from the blue key area then turn right at the end and right at the end of that path. Immediately on the left is a fake wall through which is a shotgun guy on a platform (on medium and hard skills) and a nukage pit down below, which contains a chainsaw as well as (on medium and hard skills) a medikit and a spectre (two on hard skill). There is a switch which causes the platform to lower, allowing you to jump across and out of this area. Note that entering this area activates a crushing ceiling. (sector 285)
Because one secret cannot be achieved (see Secrets section), the maximum secrets percentage obtainable is 85%.
If the player goes through the teleporter in Secret #2, he will be stuck in the south-east area unless he both has the red key and has pressed the switch near the computer map.
