Level 15: Dark Entries

From the start, open the door and proceed. Follow the right wall to an opening, clearing Imps and Lost Souls.

Enter the opening and take the teleporter. Turn around to face two windows, each with an Arachnotron. Kill them both.

Hit the switch in the west part of the room. Turn right to see a Soulsphere on a pillar. Note its initial position.

After the Soulsphere warps, pillars close and pedestals with switches appear in the south. If the Soulsphere was on the second pillar from the right, hit the switch on the second pedestal from the right (across from its original pillar).

If the correct switch is hit, the pillar lowers with the Soulsphere. Collect it. The Blue Key on the eastern pillar will then lower; collect it.

Take the teleporter in the center of the room, returning you to the start.

Follow the left wall to a set of Blue Bars. Open them and proceed through the next teleporter.

Follow the left wall to an opening and enter it. Kill the Imps and take the teleporter.

Upon teleporting, drop to the floor below. Proceed to the opening in front of you and enter it.

Reach the other end of this room where two spiral stairways are located. Ascend either stairway.

At the top, kill the Hell Knights/Barons of Hell and hit the switch. Descend the stairs.

Go through the new teleporter in the northeast part of the room. Upon teleporting, head up the stairs in front of you.

At the top, collect the Plasma Gun and proceed through the opening at the other end, avoiding darts.

Enter the opening. To your left, open a door and enter. Collect the Energy Cells and the Red Key.

Leave this small room. To your right, go through the opening and cross the pathway. Head down the stairs in front of you.

Take the teleporter across from you. You will be teleported back to the level's starting room.

Kill the Lost Souls and Arachnotrons. Proceed straight to the other end of the room.

Open the Red Door and enter. Kill the Baron of Hell and hit the exit switch.
