Post Mortem is a first-person point-and-click detective adventure set around Gus MacPherson, a former New York detective drawn into a grim Paris case. It is an older mystery game, so success comes less from speed and more from patient scene reading, careful conversation choices, and willingness to connect small details across several locations.
Content warning: Post Mortem is a mature detective thriller involving murder, blood, violence, occult themes, and non-graphic references to adult material. This guide stays focused on play habits and avoids graphic story detail.
This is a spoiler-light beginner guide. It will help you approach the case, dialogue, sketches, objects, and puzzles without turning the mystery into a step-by-step route.
Essential Tips
1. Save Before Big Conversations
Dialogue is one of Post Mortem’s main systems. The game can change its route depending on what Gus asks, how he frames a question, and which topics you choose first. Before an important interview, make a save and think like a detective rather than a checklist operator.
Do not click every line just because it appears. If two questions look similar, choose the one that best fits what you actually need from that person. A careless topic choice can close off a cleaner way to ask, while a thoughtful one can keep the scene coherent.
2. Read Every Case Item Slowly
The case file, letters, notebooks, business cards, tickets, and documents are not background clutter. They teach names, addresses, motives, aliases, and routes. When you receive written material, open it immediately and read it before sprinting to the next map point.
If a location suddenly appears, ask what told you to go there. If a person becomes important, ask which document or witness made that connection. This habit keeps the investigation from becoming random travel between Paris landmarks.
3. Use the Sketchbook as a Tool
Early progress can depend on building a suspect face from witness details, then showing that sketch to the right people. Treat descriptions like medium ears, face shape, hair, nose, eyes, mouth, lips, and facial hair as puzzle pieces, not flavor.
When someone gives a physical trait, pause and translate it into the sketchbook before the memory fades. If a witness rejects the face, adjust it calmly instead of assuming the whole lead is wrong.
4. Carry Scene Details Between Places
Post Mortem often asks you to remember what one location taught you while standing somewhere else. A hotel clue can matter at an office. A card can point to a doctor. A small object can unlock an apartment thread. The map makes travel easy, but it does not decide the next lead for you.
Keep a short note for each active question: who mentioned it, where it points, and which object might prove it. That simple structure makes branching routes less confusing.
5. Inspect Objects From the Detective Angle
Objects in this game usually have a case purpose. A newspaper can become part of a lock trick. A pencil or talisman can solve a door problem. Wine can move a police conversation forward. A camera and sketchbook can turn observations into progress.
Before using an item everywhere, describe what it could logically change. Does it distract someone, record something, reach something, reveal marks, prove identity, or open a route? That question is faster than blind item dragging.
6. Expect Old-School Navigation Friction
This is a first-person panoramic adventure from the early 2000s, and it behaves like one. You may need to turn carefully, check seats, desks, fireplaces, bathrooms, drawers, floors, and toolboxes, then revisit a room after learning why an object matters.
Move methodically through each scene. Check left, center, right, forward, and back before leaving. If the cursor changes, investigate. Some frustration comes from missing a small angle, not from misunderstanding the case.
7. Treat Puzzle Solutions as Flexible
Post Mortem is not always a single straight line. Several problems can have different routes, and the order of actions or conversations can change what you see. That is useful for replay value, but it can make walkthroughs feel mismatched if your choices diverged.
For a first run, commit to your path and solve what is in front of you. If outside help describes a step you cannot reproduce, look for the equivalent clue or person in your route instead of assuming your game is broken.
8. Use Hints in Layers
Because the story is a mystery, full answers can spoil more than the current lock or conversation. When stuck, identify the blocker first: missing location, closed dialogue route, unused document, unnoticed room detail, unsolved mechanical puzzle, or sketch mismatch.
Then seek the smallest nudge. A hint about which room to recheck is better than a complete chain of actions. The game is more satisfying when you preserve the final connection yourself.
9. Revisit People After New Leads
Characters may have little to say until Gus has the right name, object, sketch, or fact. If an interview seems dry, leave, collect more context, then return. Hotel staff, doctors, doormen, restaurant contacts, and other witnesses can become useful after the case has shifted.
Think of conversations as living gates. A person who seemed unhelpful earlier may be exactly the person to test a new suspicion.
10. Do Not Rush the Case Tone
Post Mortem mixes detective work, occult atmosphere, adult themes, and noir misdirection. Some characters may mislead you, and some scenes are built to make you doubt the cleanest explanation. Let the mood slow you down without letting it distract you from practical actions.
When the plot feels strange, return to concrete tasks: read the latest document, check the map, compare witness details, inspect the room, and decide which person has not yet been challenged with the newest lead.
Casework Flow
| Situation | Best First Move | Why It Helps |
|---|---|---|
| New interview | Save, then choose questions deliberately | Dialogue can shape the route |
| New document | Read it before traveling | Names and addresses often become leads |
| Suspect description | Update the sketchbook | Witness traits can unlock confirmation |
| New item | Ask what it can change | Objects usually solve practical blockers |
| Stuck room | Sweep every viewing angle | Small hotspots are easy to miss |
| Conflicting route help | Match the intent, not the exact step | Branching can alter the sequence |
Use this as a rhythm: talk carefully, read carefully, inspect carefully, then travel only when you know why Gus is going there.
Classic Adventure Habits
Post Mortem rewards patience with its older structure. You are expected to follow a chain from a conversation to a document, from a document to a location, and from a location to an object or witness. The game rarely needs fast reflexes, but it does expect you to remember details that were introduced ten minutes ago.
The camera and sketchbook are part of that mindset. If the game gives you a tool that records or reconstructs information, assume it exists for a reason. Use tools when a person, face, object, or room detail needs to become portable.
Mechanical puzzles require a different tempo. A lockpick setup, for example, is about understanding what the mechanism wants before forcing the final turn. Step back, watch what moves, and think about stillness, order, position, or timing. When a puzzle feels more like a contraption than a deduction, slow down and observe its feedback.
Finally, accept some first-person adventure rough edges. If nothing seems clickable, adjust your viewpoint and recheck surfaces near beds, fireplaces, desks, sinks, doors, and floors. Small objects can sit low, off-center, or behind a turn. A careful sweep beats frantic hopping between map nodes.
Common Mistakes to Avoid
- Do not click dialogue at random - similar-looking questions can lead to different outcomes.
- Do not ignore written items - files, letters, cards, tickets, and notebooks often tell you where to go next.
- Do not forget the sketchbook - witness traits are useful only if you turn them into a face.
- Do not treat items as generic keys - think about what each object would logically do.
- Do not leave a room after one camera angle - first-person scenes can hide important spots.
- Do not assume route help is exact - branching choices may change your order of events.
- Do not spend a full answer on a small stall - start with a hint and protect the mystery.
- Do not dismiss quiet characters forever - new leads can make earlier contacts useful.
- Do not skip saves before interviews - a clean save gives you room to rethink a major conversation.
- Do not chase atmosphere over tasks - return to documents, people, objects, and map logic.
