Welcome to the trophy guide for The Infectious Madness of Doctor Dekker. This can also be considered a walkthrough and may be used for PlayStation 4, Xbox One and Steam. Achievements for Steam and Xbox are in almost all cases the same as the PlayStation 4 Trophies. A roadmap is provided in the stages below.
Follow us on twitter for the latest news and giveaways.
Stage 1 – Play through the game until the end of Act 5.
Play the entire game making sure to take note of the missible trophies (Inquisitive, Hintless Wonder, Late Shift, Cher This, Youthulhu, Lucky Guess).
You will notice that every patient will have a red dot beside their name when they are available during an act. As you ask them questions they will eventually have a yellow dot (more questions/responses available) to green (all clear, everything was asked/all responses given/documents received/cut scenes shown). ALL patients MUST BE GREEN before going onto the next Act.
DO NOT PRESS DOWN ON THE DPAD! to reveal any hint(s) unless you are using backup saves. If you can not figure out what to ask a patient then save a backup, use hint(s) and reinstall your saved backup data.
Press up on the Dpad to ask a question from the ones given, left to see questions asked (note if there’s a green or yellow asterisk beside one, this means that there is more questions you need to ask the patient), and right to review your notes of important details to solving who is Doctor Dekker’s murderer. There is also the square button to review documents, triangle to ask (type) your own question(s), and touchpad to progress to the next Act (day).
It’s highly recommended to make PS+ cloud saves or USB saves in case you press down on the Dpad and especially after each Act when all patients have a green dot by their name(s) and before the time when you accuse someone being the murderer.
You can quit the game and download to your system data the saved backup to try again, repeat process until successfully determining the murder and solving the case.
Stage 2 – Only if you did not get the platinum in the first playthrough.
If you did not get the platinum trophy in your first playthrough then redownload the game save data to your system storage and proceed with which ever trophy you missed. If you moved onto another Act without all patients having a green dot by their name then you may have to replay the entire game as a new playthrough.
Trophies
Platinum Trophy
Acquire all trophies.
Unlock all other trophies.
Inquisitive
One thousand questions asked!
Ask any combination of 1000 pre-made questions (by pressing up on the Dpad) and/or your own question(s) (by using the triangle button to open a keyboard). You will notice that some questions disappear from the list so take note of the ones being offered so you can type them in when prompted, as depending on who is the murderer for your playthrough (1 of 6 possible people) they will have a slightly different set of questions through the game.
Cher This
You made Nathan sing a song.
During Act 5, you need to ask this question: Didn’t you tell me in our first session that you couldn’t time travel?
Lucky Guess
Solved Doctor Dekker’s murder without accusing any innocent people.
See The Power of Deduction description as this trophy will be earned at the same time as it.
The Power of Deduction
Solved Doctor Dekker’s murder.
At the end of Act 5 when all the patients’ have a green dot beside their names, you will proceed to the accusing phase. Before doing this make sure to make your last backup save here in case you accuse the wrong person. If you do accuse the wrong person then immediately quit the game, install the saved backup and ask someone else. Repeat until you accuse the right person.
Youthulhu
Four hundred insanity points reached.
All characters in every Act need to have a green dot beside their name in order to help reach the 400 mark. Be sure to ask all possible questions, check what questions have more followup that you need to inquire about by pressing the left button on the Dpad (they will have a yellow or green asterisks beside them). There is no in-game stat that you can check for this. This will play out every possible response, documents acquired, and cut scenes in the game for your playthrough.
Late Shift
Eight hours played.
Play the game for 8 hours either actively or having it open in an Act, but not paused.
Practitioner
Five hundred responses revealed!
Achieved by getting 500 answers that reveal relevant information to the murder of Doctor Dekker. So if you ask a question, and they respond that they don’t know what you are talking about or something like that, it does not count toward this trophy.
Hintless Wonder
Zero hints, and you absolutely didn’t cheat at all.
Play without using any hints. Do NOT use the down button on the Dpad at all through your playthrough. After every act you should backup your game save.
Registrar
Two hundred and fifty responses revealed!

Hinty Aftertaste
Solved the case using less than a hundred hints.
Unless you backup your game and reinstall the save, it is not recommended to use any hints. If you are absolutely stuck and need to use hint(s), make sure to quit the game, install the backup save to continue the game now knowing what to ask/do next in the game, as it will not change the pathway to solving who your murder suspect is.
