Oxygen Not Included Optimization Guide

Automate the daily

If a duplicant repeats a task, automate it. The freed time compounds across the whole colony.

Tighten the loops

Shorter pipes and rails mean less idle waiting. Compact designs run faster than sprawling ones.

Right duplicant, right job

Assign by trait. A strong digger digs; a smart one runs automation. Matching traits lifts output.

Measure, then cut

Watch what stalls the base and fix that loop. Optimization without measurement is merely rearranging.

Insulate for gain

Sealing heat out of farms means less cooling power spent. That is free capacity elsewhere.

Build the kit

The building database lists sweepers, rails and sensors. Use them to cut hauling.

Shrink the pipe

A shorter pipe holds less stray mass and responds faster. Trim runs when you can.

Batch the tasks

Group builds so duplicants finish one room before starting another. Fewer trips mean more work.

Use the critters

The critter database shows who produces for free. Ranch them and the base runs while you rest.

Watch the load

Automation still needs power and pipe. Size each system so the gain beats the cost it adds.

Trim the pipe

A shorter pipe holds less stray mass and reacts faster. Cut runs wherever you safely can.

Group the tasks

Group builds so duplicants finish one room before the next. Fewer trips mean more work gets done.

Breed free output

Critters that produce without power lift your yield. Ranch them and the base runs while you rest.

Frequently asked questions

What is worth optimizing?

Any loop a duplicant touches daily. Automate it and the whole colony speeds up.

Where is the easy win?

Auto-sweepers and rails remove hauling, freeing duplicants for the digging automation cannot do.
