I predict this will change, but even chlorine takes days to finish them off. Some, like Diver’s Lungs, will reduce oxygen consumption (the opposite is probably the worst trait), others are straight skill bonuses/penalties, and some negative traits like Yokel prevent your Dupes from performing a skill altogether (research, in this case).ĭespite the dramatic intro, your colonists are hard to kill at this stage. More importantly, they each have a positive and negative trait. Each has strengths and weaknesses, which you’ll tailor their jobs to. For now, though, you have your bunch of oddly adorable “redshirts,” their eyes inky pools of ignorance. I love the moral implications that the Dupes aren’t being warped into the asteroid, they’re just meaningless clones, and I’m sure that will play more heavily into the game upon release. You get to shuffle your starting Dupes, but are stuck picking from whatever the printer wants to give you later on.
I’ve found myself growing more attached to my original three Dupes than I thought I would. Latrines polluting the air? Make an air deodorizer filled with sand! Other devices, like the electrolyzer, converts water into oxygen, but produces hydrogen. Tools like terrariums filled with algae, placed in these pits of CO2, would slowly convert it back to happy oxygen. Deep pits were dug to encourage dangerous gasses away from my clones, who couldn’t be trusted to stand where they couldn’t breathe. My colony started to evolve: beds went up higher, with holes in the floors to let oxygen up/CO2 down. Heavy gasses like CO2 and deadly deadly chlorine sink, while oxygen and hydrogen float. Thankfully, the game gives you a vast array of tools to handle this, assuming you’re more competent than I am. While food, temperature, rest, and mental health are all key to the survival of your Dupes, it’s the management of gasses that rule Oxygen Not Included, and in my hubris, I had not noticed that my oxylite was gone. I also hadn’t counted on heavy pockets of it gathering on large, flat portions of my base. The game had helpfully been telling me my oxygen production was low this entire time, but I hadn’t also counted on the production of poisonous carbon dioxide.
Speaking of survival, as I dug, I noticed the bright blue of my oxygen-rich environment getting… dimmer.
