Tex Murphy: Under a Killing Moon is a 1994 first-person detective adventure developed by Access Software. The current Steam listing is published by Nightdive Studios and Atari, while the original PC release is tied to Access Software. This guide targets the classic game, not the upcoming remake.
This is a spoiler-light guide for getting comfortable with Tex’s movement, clue hunting, dialogue, and puzzle habits without listing a full day-by-day route.
The main adjustment is that Under a Killing Moon is not a flat hotspot adventure. You explore 3D rooms, change your view, look high and low, inspect small objects, and then use FMV conversations and detective tools to turn those observations into progress.
Essential Tips
1. Learn the Two-Mode Rhythm Early
Movement and interaction are separate skills.
Under a Killing Moon asks you to swap between moving through a room and stopping to investigate. Movement mode is for repositioning Tex, checking angles, and getting close to objects. Investigation mode is for cursor work, examining, picking up, talking, and using items.
Do not try to play it like a modern first-person game. Move a short distance, stop, sweep the screen, then move again. Many missed clues are not hidden behind hard logic; they are hidden behind a bad angle.
2. Search Vertically, Not Just Left to Right
Important objects can sit above, below, or behind the obvious view.
The 3D engine lets you look under desks, around furniture, up at walls, and down near the floor. Treat every room like a physical space. Check shelves, drawers, wall art, floor clutter, ledges, vents, machinery, and corners before deciding that the game has stopped giving you options.
Before blaming the clue chain, change height, rotate, zoom, and recheck nearby surfaces.
3. Use Crime Link Like a Detective Notebook
Clues become useful when you enter the exact traits.
Early progress teaches the pattern: inspect physical clues, talk to people, then narrow a suspect through Crime Link. Hair color, shoe size, build, height, blood type, eye details, tattoos, and similar traits can all matter.
When someone gives Tex a description, write it down or mentally file it immediately. If a clue appears on an object, examine it in inventory before entering anything.
4. Talk Again After Every New Lead
Old contacts can become active once Tex knows the right topic.
Chandler Avenue is not just a hub; it is a web of witnesses, merchants, friends, and suspects. A person who had nothing useful to say five minutes ago may have the next step after Tex finds a note, name, item, fax, or location.
Run dialogue patiently. Treat topic choices as clue tools, and revisit the people connected to a stalled lead before hunting randomly through every room.
5. Inspect Every Inventory Item
A pickup is often a clue container, not a finished tool.
Under a Killing Moon repeatedly uses objects that reveal more after examination. Papers can contain codes. Photographs can point to other leads. Hardware can combine with other hardware. Small items can hide a secondary use.
Open inventory after every pickup. Examine the object, then ask whether it can be read, opened, filled, altered, combined, mailed, played, scanned, or used with a machine.
6. Separate Location Travel From Puzzle Progress
New places open because Tex has learned enough, not because every old room is empty.
The game moves through a six-day case structure, with new destinations and clue chains appearing as Tex follows the mystery.
Before leaving a location, decide why you are leaving. Are you taking a name to a person, a code to a safe, a device to an office, or a lead to Crime Link? If you cannot answer that, you may still need to examine the current room, inspect inventory, or finish a conversation.
7. Write Down Codes, Passwords, Shapes, and Numbers
The game uses paper-trail logic.
Expect jigsaws, cryptograms, passwords, safe combinations, computer tasks, and device puzzles. When a fax, note, list, receipt, photo, or computer screen gives you a number or phrase, keep it visible. A small detail can become important several rooms later.
This is especially useful for old-school interface puzzles. The answer may be simple, but only if you preserve the exact spelling, order, or number group.
8. Save Before Stealth, Danger, and One-Way Moments
Some sequences are less forgiving than the investigation scenes.
Most of the game is clue work, but there are moments with security sweeps, timing pressure, disguise logic, dangerous rooms, and late-case hazards. When a scene starts warning you about patrols, traps, or enemies, create a fresh save before experimenting.
Keep more than one slot if the version you are playing allows it. A clean save before a risky area protects you from repeating a long conversation chain or item hunt.
9. Use Hints by Problem Type
Ask what kind of blocker you have before looking anything up.
A full route can spoil several discoveries at once. Instead, name the obstacle first: missing item, missing topic, code, Crime Link field, travel location, inventory combination, stealth route, or machine interface.
Then look only for that problem. If a hint system offers gradual nudges, reveal one hint, test it, and stop. Under a Killing Moon is at its best when you still make the final connection yourself.
10. Do Not Overvalue Inventory Brute Force
Many puzzles start with observation or conversation.
Inventory matters, but this is not a game where every problem is solved by rubbing every object on every hotspot. Several puzzles depend on reading the room, gathering suspect information, asking the right person, or understanding a device.
If item testing starts feeling random, step back. Re-examine the scene, check whether Tex has a clue in inventory, review the last conversation, and make sure you are at the correct location for the current day.
11. Respect the Old Interface, Then Bend It to Your Pace
Comfort is part of solving the mystery.
The controls can feel awkward because the game predates modern first-person standards. That does not mean you need to rush through them. Move in smaller increments, stop before turning sharply, and line up interactions carefully.
If the build exposes sensitivity, window, or emulator settings, tune them before a long session.
12. Keep the Remake Separate in Your Head
Classic routes are for the 1994 game.
Killing Moon Rising is a modern remake project, and its systems may not match the classic release. When using help, check that it refers to Tex Murphy: Under a Killing Moon from 1994. Future remake tips, screenshots, or modernized controls can mislead you if you are playing the original.
Investigation Flow
Start each new area by orienting yourself. Move around the perimeter, check exits, then stop in Investigation mode and sweep the room in sections. If you pick something up, inspect it immediately.
Next, talk to every available character with the current lead in mind. Conversation choices may not show Tex’s exact line, so choose based on the subject you need. When new names or places appear, revisit anyone who might connect to them.
After a clue-heavy scene, return to detective tools and devices. Crime Link, fax messages, computers, disks, photos, video gear, and physical notes all turn raw information into the next step.
When stuck, sort your blocker into one category: view angle, missing item, unexamined item, unasked topic, unentered clue, code, machine, or danger sequence. That classification narrows your next action without spoiling the whole day.
Puzzle Habits
| Habit | Why It Helps |
|---|---|
| Move, stop, inspect | Rooms are built around 3D searching |
| Examine every pickup | Items often reveal hidden details |
| Record suspect traits | Crime Link needs precise information |
| Revisit contacts | New clues can unlock useful topics |
| Save before danger | Stealth and risk scenes can cost time |
| Use gradual hints | Small nudges preserve the mystery |
Common Mistakes to Avoid
- Do not treat Movement mode as the whole game - You need Investigation mode to work the room properly.
- Do not scan rooms only at eye level - Clues can be above, below, behind, or tucked near furniture.
- Do not enter vague Crime Link guesses - Confirm traits through clues and conversations first.
- Do not leave inventory items unexamined - Many objects reveal their real value only after inspection.
- Do not assume a finished conversation stays finished - Return when Tex learns a new name or subject.
- Do not use a full walkthrough for one missing object - Identify the current blocker and solve only that.
- Do not run risky scenes without a fresh save - Security, disguise, and late-case sequences can punish blind testing.
- Do not mix classic and remake help - Advice for a modernized version may not match the 1994 game.
