Oxygen Not Included Apr 2026

Draft a "Main Spine" using Heavi-Watt Wire to connect all generators. Use Transformers to step down the power to standard wire for individual rooms to prevent circuit overloads and wire damage.

Use 25x25 pixel cells to represent the game's tile grid. You can color-code cells for different materials or gases.

When creating your blueprint, prioritize these core "early-to-mid-game" modules: oxygen not included

Drafting a layout or "paper" plan for Oxygen Not Included (ONI) is a common strategy to manage its high complexity. Because the game requires managing thermodynamic systems, gas ratios, and power grids simultaneously, players often use external tools like or graph paper to design systems before building them in-game. Essential Systems to Draft

Standardize room heights at 4 tiles high . This allows Duplicants to reach the ceiling for construction and maintenance without extra scaffolding. Draft a "Main Spine" using Heavi-Watt Wire to

If you prefer in-game planning, the Blueprints mod on Steam allows you to "copy and paste" successful designs from one area to another. Critical Math for Your Draft

Useful for quick spatial sketches of room layouts and "pipe spaghetti" management. You can color-code cells for different materials or gases

A Self-Powered Oxygen Machine (SPOM) typically uses Electrolyzers to split water into oxygen and hydrogen. Draft a design that uses a "gas-sorting" dome: hydrogen rises to the top to power a Hydrogen Generator , while oxygen is cooled and pumped to your base.
