Building a train is getting a lot more chaotic

I asked AI to build a complete playable game where I can destroy everything.

I wanted a real test instead of another static demo. Claude Opus 5.5 got my best workflows, Unity, Blender and the APIs I normally use, then ran for almost two days.

In the video I show how I prepared the brief this time, what the agent actually produced, the live playthrough, and the real numbers behind the run. — 🏆 Find the Best 3D AI Tools on 👉 https://top3d.ai

Hi all — I'm Ardis, I lead the team and direct the art on Extracto Proviso, a first-person factory game in UE5. Posted an intro elsewhere on Sunday and realised I'd listed features instead of explaining what the game actually is. Second try.

You're an android with two problems.

You're a lone android sent to a planet you know nothing about, equipped with a harvester and the ability to build a hub. From there it's automation all the way: biomass to ores, ores to buildings, buildings to technologies you were never told about.

The humans want deliveries. Every quota comes with a timer and a patience meter that slides from green to red. Let it hit red and they send troops — survivable early if you're quick, but they hit harder every time, and harder the deeper into the game you are.

The planet doesn't want you either. Once your factory starts polluting, the aliens fight back. Their nests are everywhere, and just being near one drains your stamina — running, jumping, jetpack, all of it. So you clear nests not just to fight, but to make the world walkable. When a nest breaks, eggs drop. Raise one and it becomes a companion that fights beside you, levels up with every win, and can be stationed in a nest of your own to guard the base.

The factory in between is the calm part: grid-snapped building, endless floor panels, and floating islands you can ramp up to and build on — where you may find rarer ores. Warp gates and drones move what you mine, so you're not running belts across the sky. Build ramps up to the islands, floors between them, move your whole base into the sky or just use the islands as supply. Do what you want. It's your problem now.

Where it's at: Free demo on Steam, Steam Next Fest Oct 19, Early Access Nov 2.
