Factorio (v2.0.21)

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. In the beginning, you will find yourself chopping trees, mining ores, and crafting mechanical arms and transport belts by hand, but in a short time, you can become an industrial powerhouse, with huge solar fields, oil refining and cracking, manufacture and deployment of construction and logistic robots, all for your resource needs. Add mods to increase your enjoyment, from small tweaks and helper mods to complete game overhauls, Factorio’s ground-up Modding support has allowed content creators from around the world to design interesting and innovative features. While the core gameplay is in the form of the free play scenario, there is a range of interesting challenges in the form of Scenarios. If you don’t find any maps or scenarios you enjoy,  you can create your own with the in-game Map Editor, place down entities, enemies, and terrain in any way you like.
