History VideoGame / OxygenNotIncluded

* TimeCrash: Your log entries and other emails eventually reveal that [[spoiler: the "asteroid" you are on is in fact a chunk of your home planet, which was shattered after a disastrous experiment with generating temporal energy. "Temporal Tears" still remain, leaking artifacts and materials from other dimensions]].

** Temperature is handled realistically; ConvectionSchmonvection is {{averted|Trope}}, machines that cool down gasses and liquids only transfer their heat to themselves and their surroundings, and [[UnexpectedlyRealisticGameplay ''entropy exists''.]] Normally this would eventually result in your base eventually succumbing to heat death, but there many mechanics to get rid of heat, including steam turbines, venting hot fluids into space, and the Anti Entropy Thermo-Nullifier, which cools its surroundings by breaking physics.

''Oxygen Not Included'' is a SpaceManagementGame by Creator/KleiEntertainment (of ''VideoGame/DontStarve'' fame), which can be described as ''VideoGame/DwarfFortress'' meets ''VideoGame/DontStarve'' InSpace The player indirectly controls a crew of [[ArtificialHumans duplicants]] awakened deep in a [[RandomlyGeneratedLevels procedurally generated world]]. From there, it is up to you to ensure their survival. To do this, you have to provide them with basic necessities, including oxygen, climb up the TechTree, and try and deal with [[AlmostOutOfOxygen all]] [[WizardNeedsFoodBadly sorts]] [[PottyFailure of]] [[ThePlague problems]].

* BraggingRightsReward: Breeding Crystal Shinebugs is quite the process, requiring you to go through several different 'tiers' of Shinebugs, all of which require specific, difficult to obtain food items in order to have a chance at them laying the next 'tier' of Shinebug. Ultimately, there's no real point to it unlike other creature breeding, as the main thing Crystal Shinebugs do is add an ''insane'' amount of decor where they fly around, and being able to produce high tier food generally takes care of your morale needs by itself. Similarly, Longhair Slicksters consume oxygen but produce absolutely nothing except for decor.

** If you can overcome the DifficultButAwesome requirements of cooling water and the sleet wheat farm, then berry sludge should be one of you go to food options. One farm can produce dozens of these perpeptually preserved bars, keeping your dupes fed for a long time with no fear of spoilage. Perfect for space food since it is ridiculously calory dense and and one bar can feed one dupe for four cycles. One fridge can hold 150 bars, meaning your astronaut could technically stay in space for 600 cycles.

* PlagueZombie: The [[DescriptivelyNamedSpecies Sporechid]] is a plant that has a decor value of 80,[[note]] with a range of 7 tiles[[/note]] (For reference a masterpiece large sculpting block has a decor value of 25) can be planted in a planter pot, and doesn't require any watering! A great thing to put in the middle of your base, right? [[WellThisIsNotThatTrope Well now your entire base is covered in zombie spores.]] If you're not careful when mining out an oil biome, you may come across one of these. And if the colonist that finds it isn't wearing an Atmo-Suit, then they are going to have more than they bargained for. In addition, the spores do not die off in carbon dioxide, sour gas, or crude oil, so when your colonist is bringing in an innocent looking bottle of oil to be refined, they may be exposing the entire base. Fun!

* SciFiWritersHave/NoSenseOfMass: The basic cot is made from 100 kilos of raw metal. A simple screen door is made from 100 kilos of metal ore, and the placebo pill is made from 100 kilos of water, and 100 kilos of sand. Gotta figure it 'cures' their disease because "I'd rather force myself to get better than have to try and swallow '''that'''. " A foot of wire (dupes are around 2 feet tall) requires 25 kilos of metal... but the wire can carry a kilowatt and run all the way across the asteroid with no loss, assuming it isn't overloaded and broken.

** According to some ads in Abandoned Facility biomes, the Printing Pods were originally meant to be {{Auto Kitchen}}s. Once [[EarthShatteringKaboom Earth got shattered by a kaboom,]] they were pressed into service as {{Clone Maker}}us for re-colonization efforts.
