Tex Murphy Goes 3D
Four CD-ROMs, full-motion video, and a fully explorable 3D city — Under a Killing Moon was Access Software swinging for the fences in 1994, and by most accounts it connected. The third entry in the Tex Murphy series follows the hard-boiled private eye into a near-future San Francisco as he investigates a case involving a stolen religious relic and a shadowy conspiracy. It was a landmark technical achievement for the series and for adventure gaming generally, combining cinematic FMV cutscenes with real 3D environments rather than the static, scene-based interface the earlier games used.
It’s worth pausing on just how much money and time went into four CDs of pre-rendered environments and filmed dialogue back when most PC releases still shipped on one or two floppy-sized CD images. Access Software wasn’t just making a bigger Tex Murphy game — it was betting that players would tolerate significant install and load times in exchange for a level of production value the genre hadn’t attempted before.
Investigating San Francisco
You walk Tex through his office, the streets of San Francisco, and a wide variety of interior locations, examining objects and interacting with characters much like a true 3D adventure rather than a slideshow of static screens. Dialogue and investigation stay central to the experience: conversations are frequently filmed as live-action FMV sequences with real actors, and you choose from multiple dialogue options that shape how suspects and allies respond to you. Inventory puzzles and environmental exploration are woven around these interrogations, blending traditional adventure problem-solving with Tex’s signature noir-detective tone and self-aware humor.
Tips for New Detectives
- Explore every room fully before moving the plot forward — the free 3D movement means it’s easy to miss an object simply because you never turned around and looked at a wall behind you.
- Pay attention to Tex’s own commentary when you examine things. He frequently narrates a hint about what matters and what doesn’t, which is easy to tune out if you’re used to silent adventure protagonists from earlier games.
- Don’t rush conversations. The branching dialogue rewards asking every available question before pushing a suspect, and some information genuinely locks out if you don’t ask early enough in a given scene.
- Keep the game’s in-fiction help resources in mind rather than assuming every puzzle wants a physical item — some obstacles are information puzzles that only a specific line of dialogue will resolve.
Comparing It to the Earlier Tex Murphy Games
Mean Streets and Martian Memorandum were built around static, illustrated scenes and verb-command menus — closer to a traditional graphic adventure. Under a Killing Moon throws that structure out entirely in favor of real-time first-person movement through fully rendered 3D spaces, which was a genuinely bold pivot for a series only two games deep. It paid off commercially: PC Data named it the United States’ fifth-best-selling computer game the month of its release, and total sales reached roughly 400,000 copies by the time The Pandora Directive arrived in 1996. Few series manage that kind of leap in scale between their second and third entries without losing what made the earlier games work in the first place.
Legacy: Setting Up the Pandora Directive
You can also see its influence on how later adventure games thought about branching conversation as a real design pillar rather than a cosmetic layer bolted onto a fixed story.
Under a Killing Moon’s commercial success bought Access Software the budget and confidence to push even further with The Pandora Directive two years later, which most series fans consider the high point of the Tex Murphy franchise. Beyond its own sequel, the game’s willingness to combine free 3D movement with filmed FMV performances stands as one of the more ambitious technical experiments of the CD-ROM era, attempted by very few other studios at this scale. It’s aged into a genuine touchstone for anyone studying how adventure games tried to fuse cinema and interactivity before the whole approach fell out of fashion later in the decade.
Wrangling Four CDs in DOSBox
Because Under a Killing Moon shipped across four CD-ROMs with heavy FMV content, getting it running smoothly under DOSBox takes a bit more setup than a floppy-era title. Mount your install folder with mount c [folder], switch to it with c:, and launch the executable. Our DOSBox guide covers CD-ROM mounting and memory configuration tips that specifically help with CD-based games like this one, and our free DOS games list is worth a look if you want something lighter to play between discs.
The Verdict, Decades Later
Under a Killing Moon remains one of the most ambitious swings adventure gaming took in the mid-90s, fusing genuine 3D exploration with cinematic FMV storytelling years before that combination became common. Tex’s dry wit and the game’s willingness to let conversations go badly in interesting ways still hold up as a template for branching dialogue design. Where it shows its age is load times and disc-swapping friction, which modern players raised on instant everything will find genuinely tedious even with the DOSBox workarounds, and the early-3D character models look noticeably rougher today than the live-action FMV sequences do.
That said, for anyone tracing the evolution of the adventure genre through the CD-ROM era, this one is essential, not optional. It’s a game that’s more interesting to have played than it always is to actually be playing, and I mean that as a genuine compliment to how influential its ideas turned out to be.
