This expansion highlights Klei’s commitment to deepening their simulation rather than just widening it. Instead of adding new biomes that feel disconnected from the core gameplay, they have added a new type of colonist that interacts with the existing biomes in a radically different way.

Now, let's stop talking about the distribution method and focus on the science (and chaos) these bionics bring to your colony.

Bionic Booster Pack Oxygen Not Included introduces " Bionic Duplicants

is a focused DLC released on December 12, 2024, that introduces advanced cybernetic mechanics to your colony. Unlike the massive Spaced Out! expansion, this pack is a modular addition that can be toggled on or off for both base game and Spaced Out! saves.

For a game like Oxygen Not Included , which relies heavily on replayability, the Bionic Booster Pack injects new life into the simulation. It offers a fresh challenge for players who have mastered the "standard" loop of algae terrariums and electrolyzers.

The latter is a , specifically a "Booster Pack," meaning it does not fundamentally change the rocket mechanics but instead introduces a new type of duplicant: The Bionic Duplicant.

Bionic dupes cannot learn skills instantly. They require (usually used for research) to unlock their mechanical potential. This creates a fascinating tension: Do you use your data banks for space research or to upgrade your workforce?
