Rime Asteroid

Rime Asteroid is an Asteroid Type in the game of Oxygen Not Included. It features a frozen world with some geothermal activity. Due to the unique presence of 10 out of 11 existing biomes and the in-game nature of heat management, Rime Asteroid can be considered an introductory, beginner-friendly preset.

Important Resources

Oxygen

Both sources of oxygen are available, either from Electrolyzer or Rust Deoxidizer.

Water

Filter the Polluted Water in Swamp Biome, or desalinate the Salt Water and Brine in Tide Pool Biome.

Polluted Water

Swamp Biome has Polluted Water.

Raw Minerals

Forest Biome and Caustic Biome has Igneous Rock. Swamp Biome and Tide Pool Biome has Sedimentary Rock.

Metal Ores

Caustic Biome has Iron Ore. Swamp Biome has Gold Amalgam.

Reed Fiber

Swamp Biome has seeds of Thimble Reed.

Crude Oil

The Oil Biome is frozen and has only Solid Crude Oil, which has to be heated up before any use.

Agriculture

Following Plants are available in Rime:

Mealwood

Bristle Blossom

Dusk Cap

Thimble Reed

Pincha Pepper

Balm Lily

Sleet Wheat

Wheezewort

Waterweed

Arbor Tree

Oxyfern

Nosh Sprout

Following Plants are not available in Rime:

Dasha Saltvine

Ranching

Following Critters are available in Rime and can be tamed:

Hatch

Pip

Shine Bug

Pokeshell

Puft

Shove Vole

Rime uniquely lacks wild Dreckos and Slicksters, which might lead to troubles with phosphorite (no fertilizer, domesticated Pincha Peppers, etc) and plastic production, as well as to a long-term excess of Carbon Dioxide (albeit CO2 always can be vented into space).

Since there is no other source of those critters except Printing Pod's deliveries playing on Rime with care packages turned off can provide a unique challenge.

Industry

Rime has no issue with industry.

Heat Management

The game starts in a cold state. Player has to heat the base for Plants to grow. Once the base temperature is stabilized, which can be assisted by volcanoes, it is pretty easy for the remainder of the game.

Germs

Due to the cold, Slimelung tends to die out early in the game. The germs created by Infectious Polluted Oxygen Vents and Morbs can still survive once their surroundings have warmed up.

Trivia

• Rime is named SandstoneFrozen in game code.
