Certainty Principle Hitman 3 Chongqing guide and walkthrough Image: IO Interactive via Polygon

“Certainty Principle” is a Mission Story in Hitman 3’s “End Of An Era” Mission. In Chongqing, China, Agent 47 must assume the role of Mr. Pritchard, an ICA board member, during his tour of the facility in Chongqing.

Along the way, we’ll help you earn the Climbing the Corporate Ladder, Dumplings Cook, A Hair in my Soup, Human Error, and Pocket-Sized Empire Challenges.

In this Hitman 3 guide, we’ll walk you through every step you’ll need to take. Below, we’ve got maps showing where to start, important items to find, where every clue is, and every location you’ll need to visit.

Discover the inner workings of the ICA facility.

So, someone is here for a tour of the facility. Might be a way to get in.

Mission Story Reveal

We’re going to do some prep work here — grabbing a disguise and an item you’ll need later — before picking up the Mission Story. This will save you a lot of running around later.

Before you start this Mission Story, head for the apartment building.

From Yuzhong Square in the center of the map, head into the apartment building along the northeast corner. Take the stairs all the way to the roof.

Up top, face north and look for a gap in the wall. Drop through it, and slide down the pipe. Shimmy right along the ledge, and hop through the window into the ICA Apartment.

Head down the hall on your right and into the bedroom. Listen to the answering machine to learn that Mr. Pritchard’s entry code for the facility is 0118. Pick up the P41 form under the foot of the bed. (This is also a good place to dump any illegal weapons you have — you’ll be getting frisked in a few minutes.)

Head for the Glorious Leap Sign next.

Head out the apartment’s front door and into the stairwell. Take it back up to the roof.

This time, head to the northwest corner, and cross to the balcony (this is the same route you follow in “All-Seeing Eyes” above). Take the balcony to the left all the way to the end. Jump the railing and climb the pipe.

Sneak past the sniper to enter the building.

At the top, take out the sniper if you want (you don’t have to). Your goal is the door into the building directly behind him (just to the south of the crate where you’ll likely hide his body). Open that door and head down the stairs.

Crouch when you reach Level 2. There are two guards in a room. Keep to the left wall, and put on the dumpling cook disguise (you’ll get the Dumplings Cook Discovery Challenge).

Continue past the guards and take the stairs all the way down to the Laundromat.

Now we can (finally) start the Mission Story.

Take a right and cross Yuzhong Square heading south. Enter the building on the south side, and take the stairs up to the Restaurant.

Grab a seat on the bench and listen to the nearby conversation to start the “Certainty Principle” Mission Story.

Listen in on the conversation

Keep your seat until the pair are done talking. We already grabbed the P41 form, so you won’t get that objective.

On her way out, Chen Ting will mention that Pritchard is starving. Let’s do something about that.

Disguise yourself at the board member

Go through the door on the east side of the restaurant into the bathroom. Pick up the emetic rat poison from the stool on your right, and then climb through the window on your left. Shimmy a little to the left, and then climb through the window into the kitchen.

Sneak into the kitchen to poison the board member.

Head to the closest workstation, and prepare some food. When it’s ready, poison it, and then ring the bell. Duck back out the window and position yourself outside the bathroom.

One of the other cooks will take your (poisoned) food to Mr. Pritchard, and you’ll get the A Hair in My Soup Feat Challenge. Wait for him to rush into the bathroom, and subdue or drown him. Put on the board member disguise, and stash Pritchard’s body in the laundry bin.

Talk to the guide // Follow the guide // Give the P41 form to the facility guide

Head back through the Restaurant and its kitchen to find your guide. Let her know you’re ready. Follow her into the ICA Facility. Hand over the P41 form when she asks for it (much later).

Approach the guards to get frisked

While she’s setting up, you’ll need to get rid of anything illegal you’ve acquired before you go through the frisk. There are two trash cans where you can hide weapons, and an out-of-the-way server room to the south of you where you can dump anything else.

When you’re clean, head for the frisking.

Follow the guide

Use your camera to darken the glass on the left and then hack the computer.

Rejoin the guide and continue your tour. She’ll lead you to the Vetting Room, where you’ll have a brief panic about your ID. Use your camera to darken the glass on your left. When it’s opaque, hack the laptop right there to straighten out your ID.

Rejoin the guide again, and she’ll lead you to Imogen Royce.

Follow Royce // Listen to Royce

Follow Imogen as she gives you her spiel. When she gives you control over the demonstration, you’ll complete the “Certainty Principle” Mission Story.

Medium Rare Assassination Challenge

While you’re here, though, let’s use the system to cause some problems.

  • Fire Alicia Reynolds as soon as you can. She’ll turn off the safety mechanisms.
  • Fire Jeremy Bolt next, right after Alicia. He’ll hop on the phone immediately, and will distract Royce’s own bodyguard.
  • Keep an eye on the security camera feeds, and fire Sharon Reed when you see Royce inside the Data Core room.

If you time it right (it’s very tricky), you’ll take out Royce while earning the Human Error Feat Challenge and the Medium Rare Assassination Challenge.
