MAP27: The Lab is a level in Strife. It uses the music track "Tech".


Spoiler Warning: Plot details follow.

After fighting through the proving grounds, you enter a laboratory where the Loremaster, who oversees the process that converts humans into acolytes, resides. You engage the Loremaster in combat, kill him then destroy the spectre that was possessing his body to obtain a Sigil piece.

If you are following the Oracle's instructions, you must return to it to acquire the fifth and final Sigil piece. Otherwise, armed with the complete Sigil, you use it to open the entrance to an alien vessel.

Spoilers end here.


Map of The Lab
Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets.


Open the door and go through to be "welcomed" by the Loremaster's voice. There will be a templar in front of you on Veteran skill level, or two on Elite or Bloodbath; destroy them and approach the switch they are guarding, but do not pull it yet - two inquisitors will have been alerted to your presence and should be destroyed before you face the Loremaster. If the inquisitors are on the ground below the ledge you are standing on, they may get stuck trying to jetpack up to you; if this happens you can shoot at them as they jump.

Once the inquisitors are destroyed and you are ready to fight, pull the switch and the Loremaster will be revealed on a high platform in front of you. The Loremaster is a flying enemy who attacks using a grappling hook - the hook itself deals minor damage, but if you are pulled off a high ledge then you will suffer a lot of falling damage. Because the Loremaster is a small enemy, it is advisable to use hitscan weapons like the assault rifle or mauler depending on your range.

Once the Loremaster is destroyed a spectre will emerge from his corpse - it is the strongest of all the spectres and its Sigil shots will fire lightning bolts ahead and to the sides, so using cover is strongly recommended. Once the spectre is destroyed, you will obtain the fourth or fifth piece of the Sigil depending on whether you are following the Oracle's directions. If you are following the Oracle, you will need to return to its temple by backtracking through the proving grounds then come back here once you have the complete Sigil, otherwise you can now proceed to the endgame.

From the level entrance, approach the switch that released the Loremaster and jump east across the platforms to an opening in the wall. Turn left and go down the steps, then step on the hazard markings to raise a lift which will take you to the bottom floor. Turn right and head for the large gate to find a square tile with a Sigil symbol on it - pressing use on this tile while carrying the complete Sigil will open the wall ahead. Go through and step on the green lift ahead to be taken down to a passage leading to the alien ship.

Other points of interest[edit]

From the level entrance, turn left and head down two sets of steps to find a large metal doorway with a button. Press the button to reveal a chamber full of "becoming" acolytes, humans who are partway through being processed into Order soldiers. Head through this room and open the door at the west end to find a room with four medical kits. (Once the chamber is opened, making any noise will cause the alcoves to seal and a large number of acolytes will teleport in, representing the "becoming" acolytes being fully processed. Fire some phosphorous grenades into the chamber to incinerate the acolytes as they appear.)

On reaching the bottom floor, head west around the Loremaster's platform to find another lift leading up to a ledge with several pickups. There is also a teleporter which leads to another ledge across the room, holding an energy pack and two med patches.



There are no official secrets in this level in the original game. The Veteran Edition changed the non-official area below to an official secret.


  • A person works in a room in the east. Go there and break the computer screen on the southern wall in order to get through the wall. A hidden room contains two medical kits, three mini-missiles and a unit of phosphorous grenades. (sector 129)
