Charles Milton Porter, the founder of Rapture Central Computing and inventor of its advanced mainframe, “The Thinker,” needs your help to escape Rapture. First, you need to go to his office and begin preparations. Head through Rapture Central Computing Executive Wing to find the office of C.M. Porter.
Executive Wing
Don’t let that shiny Plasmid lure you into a mistake! Before you approach the reception desk and claim the Security Command Plasmid and EVE Hypo, step beneath the Security Camera on the left and hack it. Hacking this Security Camera pays dividends later on as you return through this area. Ignore the storage closet on the right for now, as it’s guarded by a Turret and you’re not well-equipped to deal with it just yet. Enter the Executive Wing via the door to the left of the reception desk.
Bypass the Gatherer’s Garden for the time being—you’ll be passing back through momentarily—and approach the short-circuiting Vacuum Bot down the hall. Smash it with your Drill to receive some valuables, perhaps a First Aid Kit and money.
Ascend the stairs to the right of the main hallway and enter the flooded office. There’s an SMG Turret in the opposite corner, beyond the partitions. Splash the Splicers with Security Command to turn the Turret against them, use Telekinesis to grab the First Aid Kit inside the wall at the top of the stairs, then leap over the railing to avoid the Turret. Take out the other Splicers and dash through the doorway without destroying the Turret. Raid the desks and filing cabinets, then hack the Safe in the back room to gain 40 Dollars, 2 EVE Hypos, and 100 Laser Cells.
Two Spider Splicers enter the room after you hack the Safe. Hit them with Security Command to enlist the help of the Turret. Make your way up the stairs and out of sight of the Turret while it opens fire on the Spider Splicers.
Back in the hallway, around the corner from where you found the Vacuum Bot, a Splicer will attack with a Rocket Security Bot. Take out the Splicer and hack the Security Bot to gain it as an ally. Ignore the large room of offices on the left and continue toward the Circus of Values machine up ahead. The door to C.M. Porter’s office is currently locked and, though you don’t know it yet, you’re going to need the Hack Tool to open it. Head into the Boardroom opposite the vending machine to get the Hack Tool.
Collect the Audio Diary (“The Predictive Equation”) from the corpse in the center of the room and the ADAM Slug from the pool behind it. Descend the stairs on the left to the basement and pick up the Hack Tool from the ledge to the left of the locked door. Fire the Remote Hack Dart through the hole in the wall beside the locked door to hack the Door Control panel. Enter the small room to claim the Hacker’s Delight tonic.
The door leading back to the stairs locks shut as you approach. Use the Hack Tool to hack the Door Control panel beyond the hole in the wall just as you did moments ago. Fight your way past the Splicers in the Boardroom, making sure to hack the Electric Security Bot belonging to the Leadhead Splicer to gain yourself a second helper. C.M. Porter’s office is just down the hall from the Boardroom. Hack your way through the door via the hole in the window and proceed through the tunnel to the office.
