Map of Terror Core
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.


The starting room contains four teleporters leading to four different areas. The white teleporter in the south-west of your starting position will lead to the exit door, but as it requires the three coloured keycards to open, there is no need to go there until the end of the level, so grab the shotgun in front of you and choose any of the other three teleporters.

The northwestern teleporter will lead you to a metallic platform in front of a small cave. There are imps below, and climbing down the stairs reveals shotgun guys hiding behind the wall. Kill all of them and enter one of two pathways leading to the rest of the cave, where a switch will cause the blue keycard to appear in the slime pool in front of the platform. The northeastern teleporter will take you to another cave with water and trees around: kill the imps in front of you and take the lift to descend to the lower section of the cave, where you will be met with more imps and shotgun guys, which should be killed quickly to prevent them from overwhelming you. Press the switch here and the yellow card will appear in the water pool in the upper section. The southeastern teleporter will take you to the trickiest encounter, a small room with a shotgun guy on each side and several imps on an elevated platform. Taking the stairs up to the platform will net you the red key but also cause two chaingunners to appear below.

With all keys in your possession you can now enter the white teleporter. Avoid getting pinned down by the pinkies you spawn in front of, and you can then open the locks and exit the level.

Other points of interest[edit]


  1. When you press the switch at the start, run off the platform in any cardinal direction going over the railing until you hit the water below (if you fail to do this, you can still head over the railing by taking any of the teleporters, then re-entering them and then running to the closest railing). You will find a chainsaw, a box of shotgun shells, a box of ammo, a green armor, and armor bonuses down here. (sector 1)
