Cooling Facility

Cooling Facility is an industrial facility that produces the coolant liquid for the Strogg reactor and the other machinery in the power plant. The area consists of several large yards with water pools on the surface, and a system of subterranean canals.

Unlike the coolant liquid in the previous level, the water is safe to swim in.

This level contains a curious easter egg, which becomes accessible only after the reactor has been destroyed.

Quick Level Completion

 * #1) When you drop down into the sewer area where the Technicians are located, take a left at the intersection and look at the left side of the next room to spot a ladder on the wall. Carefully jump to it and climb down and head into the secret room down here to find Health, Bullets, Grenades and an Adrenaline.
 * #2) In the big room with the two elevators leading up out of the water, take the right elevator, go to the right once you reach the top and look down towards the elevator; there is a secret Megahealth on the ledge here. Simply drop down to it (do not jump) and pick it up.
 * #3) In the room where you must turn a valve and push a button to complete the level's objectives, activate both objects and drop back down to the lower level, where the valve is located; a portion of wall has exploded, revealing the final secret, containing a Quad Damage, a Railgun, and a suit of Body Armor.
