Chemistry
Mastering molecular conversion to sustain life on the asteroid.
In the Oxygen Not Included universe, 'Chemistry' refers to the critical set of Mission Objectives centered on molecular conversion and resource management. While not a single named chapter in Story Mode, this thematic phase encompasses the Water and Oxygen missions where Duplicants must synthesize breathable air from available resources. These objectives serve as the foundational challenge for new colonies, forcing players to understand gas behaviors, liquid states, and energy consumption. Success here is mandatory to progress beyond immediate survival threats like suffocation or toxicity.
- Primary Tools
- Electrolyzer, Algae Terrarium
Lore & Background
The Duplicants arrived on the asteroid with limited supplies, relying entirely on their ability to manipulate matter for survival. The concept of Chemistry in this context is not merely academic but a literal lifeline; without converting water into oxygen or scrubbing carbon dioxide, the colony suffocates within days. This necessity drove early technological development, leading to the creation of the Electrolyzer and Algae systems. These inventions represent humanity's adaptation to an alien environment where natural cycles are absent. The struggle against chemical imbalance defines the early narrative arc, highlighting the fragility of life support in a vacuum-sealed rock. Over time, mastery over these reactions allows for more complex engineering, such as thermal regulation and food production. The chemistry objectives thus act as a rite of passage, transforming desperate survivors into competent engineers capable of terraforming their small pocket of space.
In Their Own Story
The air in the lower cavern felt heavy, thick with invisible weight. Duplicant Unit 73 adjusted her helmet seal, watching the red warning light pulse on the console. The Electrolyzer had stalled again, water pooling dangerously near the power couplings. She checked the gas sensors. Oxygen levels were dipping below critical thresholds while Hydrogen built up in the sealed chamber above. A spark here would be catastrophic. With steady hands, she rerouted a liquid pipe to drain the excess, then tapped the maintenance panel to reset the flow valves. The hum of machinery returned, a rhythmic breathing sound that meant life could continue for another cycle.
Reader's Guide
To succeed in early colony management, Duplicants must master chemical conversion processes. The primary objective involves utilizing Water to generate breathable Oxygen through electrolysis or photosynthesis. Players construct Electrolyzers powered by electricity or grow Algae Beds consuming Carbon Dioxide. Balancing inputs prevents suffocation and toxic buildup. Completing these objectives unlocks further technology, such as Gas Pipes for efficient transport. It is crucial to manage Hydrogen waste carefully, as it accumulates rapidly and causes explosions if confined. Additionally, players must monitor temperature to prevent liquids from freezing or boiling unexpectedly. Ensure adequate power supply for Electrolyzers, as they consume significant energy. Monitor liquid levels in tanks to prevent overflows that block pathways. Understanding gas density is vital; heavier gases like Carbon Dioxide settle low, requiring ventilation at floor level. These chemical tasks advance the story by proving the colony can sustain life beyond basic survival. Success transitions the narrative from immediate crisis management to long-term infrastructure planning.
Did You Know?
- Carbon Dioxide is denser than Oxygen and sinks to the lowest levels of a room if not ventilated.
- Electrolysis splits Water into Hydrogen and Oxygen, but Hydrogen gas is highly explosive in high concentrations.
- Algae Terrariums consume Algae and produce Oxygen from Carbon Dioxide regardless of light conditions.
- Liquid Oxygen cannot form naturally under standard gameplay conditions; it must be produced by cooling Oxygen gas below its condensation point using player-built machinery.
Frequently Asked Questions
Who is Chemistry?
Chemistry is not a specific character but rather the core gameplay theme encompassing the early Water and Oxygen missions where Duplicants must manage molecular conversion. It represents the critical phase of survival focused on synthesizing breathable air from raw resources found on the asteroid.
What are the primary tools used in Chemistry objectives?
Players primarily rely on Electrolyzers to split water into oxygen and hydrogen, as well as Algae Beds which consume carbon dioxide to produce oxygen. Mastering these tools is essential for maintaining a breathable atmosphere before advancing to later game stages.
Why is managing Hydrogen so important during this phase?
Hydrogen accumulates rapidly when using Electrolyzers and poses a severe explosion risk if it builds up in enclosed spaces without proper venting. Ignoring this byproduct can destroy your colony, making its management just as vital as producing oxygen.
How does the Chemistry theme conclude?
This thematic phase effectively ends once Duplicants successfully stabilize their oxygen levels and eliminate immediate suffocation threats through established production loops. Success here allows players to progress beyond basic survival into more complex resource management challenges.
What resources are critical for starting Chemistry objectives?
Water is the fundamental input required for electrolysis, while Carbon Dioxide serves as a key feedstock for biological oxygen generation via Algae Beds. Without securing these initial liquid and gas resources, creating a sustainable atmosphere is impossible.
