The path to Upper Heat Loss Monitoring leads you through a machinery-filled room littered with the corpses of those who’ve come before you. The lights go out twice while you cross the room, but it isn’t until you near the corpses closest to the exit that you need to be afraid. Prepare for the ambush by the Houdini Splicers playing dead by using Telekinesis to carry one of the flammable cylinders or explosive drums with you across the room. As soon as the Splicers get off the floor, back away and throw the makeshift bomb at them. Retreat to the near side of the room and use Telekinesis to hurl another cylinder at those who survived the first blast.
Little Sister Encounter
Big Daddy: Elite Bouncer
Enter the room and loop around to the right quickly, as the Little Sister in this area is growing tired and her Big Daddy is about to put her back into her hole for the night.
Place any Proximity Mines you have near the small set of steps leading down to the walkway where the Big Daddy is, then use the Target Dummy plasmid to place a dummy near the Proximity Mines. Move back a few steps and fire a Heat-Seeking RPG at it to get its attention. If you placed everything properly, the Elite Bouncer storms towards the Target Dummy and hit the Proximity Mines. This gives you a chance to unload on it with Armor-Piercing Auto Rounds from afar.
Spend your take at the Circus of Values machine and descend the stairs to Lower Heat Loss Monitoring. Hack the circuit breaker on the left to disable the electric current flowing into the water below. Search the area at the base of the left-hand stairs, then climb back to the central area and battle the two Splicers that appear—a well-aimed shot should detonate the drums in the middle of the floor and kill them both.
Descend the other set of stairs and pick up the Security Evasion 2 tonic on the desk. Of even more importance than this valuable tonic is the Audio Diary next to it—it’s from Pablo Navarro and he’s speaking about telling Anya to visit Kyburz’s workshop.
