FLUXWERKS

Start with these

FluxWerks is a factory automation game where the planet is genuinely simulated rather than painted onto a flat grid — terrain, the heat in your boilers and the fluids in your pipes all behave physically, and your factory has to live with the consequences. It entered Early Access on Steam on September 23, 2026, developed and published by Metallibitti Oy.

Start with your next factory problem: stable power, a fluid route that keeps moving, or enough production for the next build. The guides below separate released mechanics from upcoming previews.

What the game actually is

You dig into an infinite destructible voxel world, tame heat and steam, and build factories that stretch to the horizon. The four systems the developer leads with:

1. An infinite world you can reshape — every block can be mined, excavated or built over: shafts to deep ore veins, canals for cooling water, flattened mountains, tunnels for logistics.
2. Heat that behaves like heat — temperature is simulated across the world and inside machines. Boilers feed steam turbines, furnaces warm their surroundings, snow melts, water boils away.
3. Fluids with real flow — water, lava, oil and stranger substances flow, pool and press against your works; fluids react where they meet, lava hardens into rock in cooling channels, hot springs can power an early base.
4. Weather with teeth — each biome has its own temper.

Launch facts

The three systems that decide everything

Heat is a failure mode you engineer around, not a bar you fill. Waste heat accumulates unless you build exchangers and thermostats — the developer's own wording is that you manage it "before your factory cooks itself." Full detail on Heat & Steam.

Fluids are simulated, so pipe routing is a thermal decision. Route by temperature, not by distance, or lava will harden into rock inside your own cooling channel. See Fluids & Pipes.

Logistics is where the map fights back — belts, tunnels through rock, drones from v0.5.13, and router corners that auto-feed from v0.5.16. See Logistics & Drones.

Choose the guide for the problem

Start with the first-hour checklist for inventory rules and work priorities. Use Heat & Steam when generation or battery charging falls behind, and Fluids & Pipes when a filtered route stops moving. For farm sizing and extraction changes, open the Production Planner guide.

The latest released update in the official news feed is v0.5.21. The October 31 developer preview expands the next update into 0.6, including nuclear power, logic networks and a configurable hotbar. Those are upcoming features; keep using the v0.5.x rules below until a release announcement says otherwise.
