Factorio is a game in which you build and maintain factories.
You will be mining resources, researching technologies, building infrastructure, automating production, and fighting enemies. Use your imagination to design your factory, combine simple elements into ingenious structures, apply management skills to keep it working, and protect it from the creatures who don't really like you.
The game is very stable and optimized for building massive factories. You can create your own maps, write mods in Lua, or play with friends via Multiplayer.
Factorio was in development from the spring of 2012 to the beginning of 2021. So far over 3,500,000 people have bought the game. You can get it from Steam, GOG, or directly from our shop.

Factorio does not fill the niche. It creates the niche.
Hello, We all love building bigger and bigger, but hitting the UPS ceiling really puts a damper on the mood. Thats why we must continue our endless quest to optimize the game.
Hello, I'm sure you're familiar with the good old Nuclear reactor. It's a fission reactor that makes a lot of power in conjunction with its steam turbines. The nuclear energy system is unlocked on Nauvis, and in the context of Space Age, that makes it an early-to-mid game unlock. For the planet Nauvis, nuclear power is great for the whole game. Water is endless, and uranium is plentiful. For space platforms it's not ideal because it takes a lot of water and a fair amount of space. Solar panels are so good in space, especially near the sun, that it's harder to justify a reactor on a small platform. If you're mainly going around Fulgora then nuclear becomes more competitive because Fulgora has more ice from asteroids and less solar energy. Later, when you head to the 4th new planet, nuclear becomes a much better option because the solar power is so low and ice is more abundant. At that point, you've had nuclear as an option for all the 5 planets (although you probably don't use it on all of them), and a few space routes, so it's time to unlock a new and exciting energy system.
