Quake II/Torture Chambers

Level objective
The objective for this level is to retrieve the Data CD from Cell Block A and gain access to Cell Block B.

Shortly after entering the Torture Chambers area, you will engage a Tank at the mouth of the tunnel, just beyond a lift platform that descends to a lower level. After eliminating the Tank, mind the gap as you jump off the platform and go outside, turn right and double back along the outside of the tunnel portal structure to find Secret 1. Return to the tunnel portal, step on the floor switch and ride the lift down to a lower level.

The Data CD is to be found in a wall niche on the second level at the west end of Cell Block A. The niche is secured by a force field, which can be temporarily switched off by pushing the large red button on the wall just to the right of it. Secret 2 is also found in one of the cells in Cell Block A; be certain to find it before attempting to reach Secret 3.

(Expand this section)

Use the Invulnerability item found earlier in Secret 2 to jump into the lava vat and find Secret 3. If you've eliminated all enemies but one in this area, take the lift up from the floor where the lava vat is and head for the exit, just steps away. The Torture Chambers area exit door is clearly marked, but is guarded by a Tank. Destroy him and move through the airlock to the Security Complex. This finally gives you access to the catwalk that you saw earlier and leads to the mezzanine that overlooks the entrance to the Guard House. (If the mezzanine lift isn't working, it means you missed a trigger event in the Torture Chambers. You can return and attempt to push various buttons, or just jump to the ground.)  If you've already retrieved the Pyramid Key from the Guard House area, you can proceed to the Pyramid; otherwise, enter the ../Guard House/.

Secrets
This level has three (3) secrets:
 * 1) Shortly after entering the Torture Chambers area, exit the tunnel portal, turn right and double back along the outside of the tunnel portal structure (head east) to find an HyperBlaster and Cells.
 * 2) In Cell Block A, shoot the base course block in the back wall of the second cell from the left.  Crawl into the hole to find a secret chamber containing an Invulnerability item.
 * 3) A large, rectangular vat filled with lava contains a Quad Damage and a number of munitions items at the bottom.  Use the Invulnerability item you found previously in Cell Block A to dive in and collect them.  Swim to the surface and get onto the lip of the vat.  There is no easy way off the lip; walk toward a corner and slide down one of the tapered buttresses on the side.  If you're lucky, you won't take any damage getting down to the floor.
