Place the hair sample in the pneumo tube once you’re back at the Silver Fin Restaurant, in Suchong’s lab. After an unexpected message from Andrew Ryan, you’ll be given 60 seconds to prepare for an ambush.
Defend Against Ryan’s Henchmen
Elizabeth will talk about the need to set up traps. And traps will work, provided they’re in the right place. Unfortunately, two of Ryan’s henchmen are Houdini Splicers who aren’t likely to step in any traps. Nevertheless, turn your back to the screen and place a Possession trap on the floor near the exit. Now hurry upstairs to the area overlooking the Lutece device. Don’t worry about setting other traps, since you can launch them from here. Top off your EVE via the pneumo tube near the upstairs door. Equip the Radar Range and wait for their arrival.
Kill the Houdini Splicer with the Radar Range as soon as it teleports upstairs near your position. Two thugs will come through the door, shortly after setting off your trap. Use Peeping Tom to monitor the arrival of the others through the walls and hit any with a gun or with Possession. Two more thugs and a final Houdini Splicer appear last. Use the Radar Range once again, preferably while they’re grouped together. If you don’t have enough ammo for the Radar Range, hit the Houdini Splicer with a Tranquilizer Dart, then rush forward and knock him out with a melee strike.
Go to Fontaine’s Office
In order to raise the department store you need to return to the Manta Ray Lounge and use the private elevator located upstairs to reach the top floor. There’s a full-blown war raging inside the Bathyspheres DeLuxe and it’s best if you stay out of it. Exit the restaurant and spot the Manta Ray Lounge off to the left, behind the large sign. Cast Possession on any Houdini Splicers you encounter, otherwise use Peeping Tom and the freight hooks to cross the battlefield undetected. Sprint into the Lounge and up the stairs on the left as quickly as you can.
Manta Ray Lounge
Lie low and wait for the thugs you see on the second floor to dissipate. Eliminate any stragglers as stealthily as you can, descend the curving stairs on the left, and fire a Noisemaker at the main bar off to the right. With the enemies drawn to the right, you can sprint past the fallen chandeliers to the doors you unlocked earlier.
Slip upstairs through the store room, use another Noisemaker aimed to the far right, and sprint past the bar to the executive elevator—Atlas had it unlocked just as he said he would.
