About Oxygen Not Included
Klei Entertainment dropped this space colony sim on PC, Mac, and Linux in July 2019. You manage a group of duplicants stuck inside an asteroid while they try not to suffocate or starve. The game forces you to balance basic survival needs with complex engineering problems. It is a single-player title that focuses on managing resources like oxygen, water, and heat within a confined environment. You must dig tunnels, build pipes, and grow crops just to keep the population alive. The aesthetic is clean and bright despite the grim circumstances of being trapped in rock. This simulation challenges your ability to plan ahead while dealing with chaotic physics and unpredictable alien bugs.
Gameplay
You start by placing a drill to extract ore and then immediately worry about air quality. Every minute involves checking gas levels and moving liquids through pipes before they boil or freeze. You assign tasks like mining, farming, or cooking based on your crew skills and current needs. The game runs in real time but lets you pause to issue commands without penalty. Managing temperature is a constant struggle because heat builds up faster than you can vent it. You construct complex facilities like oxygenators and water recyclers to prevent asphyxiation. When something breaks, you scramble to fix the leak or replace the machine before everyone dies of carbon dioxide poisoning.
What Players Think
The IGDB community rates this title 78.3 out of 100 based on 126 reviews. Players spend an average of 45 hours completing their first run before giving up or finishing the main goals. Only 11.3% of achievements unlock on average, showing how difficult the content is. The rarest challenge "The Lab: Life Found A Way" appears in just 0.20% of saves. Many users report feeling stressed when a pipe bursts at 3 AM in-game time. Critics praise the depth but note the steep learning curve scares off casual fans. The mood shifts from panicked to satisfied as you master the gas physics. Most players admit they spend hours tweaking their base layout to optimize efficiency.
PlayPile's Take
This game costs money and demands patience if you want to see a stable colony. You should only buy it if you enjoy solving engineering puzzles under pressure. The 50 achievements offer long-term goals for those who finish the tutorial phase. Do not expect hand-holding or easy victories since death is frequent. Klei Entertainment built a system where one mistake can wipe out your entire crew. If you like watching numbers go down and then figuring out how to fix them, this fits your schedule. Just be ready to lose dozens of duplicants before you get the hang of it.
