SOL: The Last Imperium: The 24-Hour AI Sci-Fi FPS Preview

A sci-fi FPS that exists only as a preview

I built the world’s first AAA-quality sci-fi FPS game with AI in 24h. On my laptop. While traveling.

SOL: The Last Imperium is Rubzem’s own IP: a science-fiction first-person shooter announced on November 5, 2026. The creator framed it as the follow-up to leaving an 11-year corporate career to make games with AI. What exists so far is a short preview, not a site, download, or playable build.

The combat pitch is specific even if the rules are not. You are promised fast first-person fighting with guns, grenades, and melee; the ability to drive, fly, and fight across large battlefields; and giant boss battles against walkers, titans, and a Leviathan. No scoring system, win condition, stage list, or control scheme has been published, so none of those can be treated as known.

How Rubzem says the 24-hour build was made

Now it feels like I have an entire $100M game studio on my laptop.

Rubzem says graphics, gameplay, concept art, music, sound effects, and animation were all made with AI and entirely vibe coded, on Three.js. The model pipeline described is Tripo for world-class 3D characters, vehicles, and monuments, then Opus 5.5 working with Blender to push those models toward a higher-end look. The creator calls that pairing an absolute game changer and compares the laptop setup to having a $100 million studio.

That stack is why people are treating this as more than a mood reel. Three.js is a web 3D library, and the feature list reads like an open-world shooter rather than a one-button casual game. Until a build ships, though, the 24-hour AAA claim stays a creator statement about the preview, not a result you can time or score yourself.

• Tripo

  Used for 3D models of characters, vehicles, and monuments.

• Opus 5.5 and Blender

  Described as the step that refines those models toward the look Rubzem wants.

• Three.js

  The engine the game is built on, which points at a browser-style 3D project.

The Gamescom offer, as Rubzem tells it

Rubzem says a giant company in the game industry got in touch after an earlier AI game drew wide attention. The stated offer is to feature a game made with AI in the company’s million-dollar booth at Gamescom and to help release it worldwide across platforms. SOL: The Last Imperium is presented as the original IP for that moment.

The company is not named, and no public page confirms a booth slot, a release window, or which platforms. Read the contact as part of the announcement, alongside the call to start creating now. The creator also said more AI game-dev detail would be shared in the comments on that announcement.

Where it sits among quick web shooters

Typical casual browser shooters give you one weapon, a tiny arena, and a score before the tab gets boring. SOL: The Last Imperium is pitched in the opposite direction: epic guns plus grenades and melee, vehicles and flight, huge battlefields, and set-piece bosses, with art, music, effects, and animation credited to an AI pipeline. If a playable Three.js build ever matches that preview, it would be closer to a compact campaign shooter than to a score-attack toy.

Right now the satisfying part is the ambition, not a loop you can master. There is no confirmed way to strafe, aim, drive, or dodge the Leviathan, and no difficulty curve to learn. Similar one-sitting web games win on instant access. This one is recently trending as a production story—an original sci-fi FPS a solo creator says was vibe coded in a day—while the game itself remains unreleased.
