The 3DO just got a new sci-fi horror shooter called Terminus

Homebrew developer Retro Love Letter has released a playable demo for Terminus, a new 3D sci-fi horror game built specifically for the 3DO Interactive Multiplayer console. The playable demo for Terminus was available on or before March 23, 2026, and is currently available to download.

I have been playing the demo, and it is a beautiful first-person shooter that runs at a smooth 30 frames per second. There are almost no load times either. It looks fantastic in motion. Honestly, if more games like this existed when the 3DO was new, the console possibly could have survived the 32-bit generation.

Following up BioFury

Retro Love Letter is not new to this specific hardware. The developer previously released BioFury, a zombie-based first-person shooter that also pushed the console's 3D capabilities. Their resume also includes an impressive port of the arcade game Tempest and an original title called Wreckman. They have spent years figuring out how to squeeze modern performance out of a notoriously difficult platform.

Terminus leans heavily into sci-fi horror. The environments are dark, moody, and filled with texture-mapped corridors that look far more advanced than the typical 3DO library. The lighting engine creates a genuine sense of tension. Most commercial releases for the system relied heavily on full-motion video or flat 2D sprites. Seeing a fully realized 3D environment moving this quickly on original hardware is jarring in the best way possible.

The custom silicon problem

Developing for the 3DO is not a simple task. The console uses a 32-bit RISC CPU based on the ARM60 architecture, paired with two custom video co-processors. Those co-processors were designed to manipulate quads rather than the triangles used by modern 3D graphics hardware. This unique setup means developers cannot simply drop standard 3D engines onto the system. Everything has to be custom-built to handle the quad-rendering pipeline.

Getting a first-person shooter to maintain a stable frame rate under these conditions requires serious optimization. The fact that Terminus achieves 30 frames per second while rendering detailed environments is a massive technical achievement. The lack of load times between areas is just as impressive. The console only has a single-speed CD-ROM drive, after all.

The $700 elephant in the room

The 3DO launched in North America on October 4, 1993. Conceived by Electronic Arts founder Trip Hawkins, the system was originally envisioned as an open standard. Hardware manufacturers like Panasonic, GoldStar, and Sanyo built the actual units. The technology was incredibly advanced for the time, but it came with a massive barrier to entry. The original Panasonic model launched at $699.99.

That price tag doomed the console. By the time Sony and Sega arrived with the PlayStation and Saturn, the 3DO was already struggling to maintain market share. It was officially discontinued in 1996. The system developed a reputation for interactive movies like Night Trap and early PC ports rather than fast-paced action games. Terminus feels like a glimpse into an alternate timeline where the console received optimized, dedicated 3D shooters.

Burning a disc

The current build is available directly from the project repository. The 3DO does not have copy protection, making it one of the easiest retro consoles for testing homebrew software.

The game also runs perfectly fine on modern emulators like Opera. The project is still in active development, and Retro Love Letter frequently posts progress updates that show new weapons and enemy types. The final release date is currently unknown, but the playable slice offers plenty of reasons to dust off your old Panasonic hardware.
