About
Your journey begins on a remote island with a small crew of workers and a ship full of supplies. Mine raw materials, reshape the fully dynamic terrain, grow crops, build factories, and research new technologies. Expand across the island, lay rail networks, trade with distant settlements, and work your way up to nuclear power and space flight.
The entire terrain is fully dynamic. Every mountain can be flattened, every valley filled, and even the ocean can be reclaimed to expand the available land. Create open-pit mines to reach deep ore deposits, or dump excess rock into the ocean to expand your shoreline. Build ramps and slopes so your vehicles can reach any elevation.
Start simple with iron smelting, concrete mixing, and food processing. As you research new technologies, expand into oil refining, electronics, computing, and eventually rocket and space station components. Manage waste and pollution before they affect your people's health.

Trucks handle general logistics automatically, delivering products where they are needed most. Lay conveyor belts and pipes for high-throughput direct connections between machines. Build a rail network to move bulk cargo across long distances. Use amphibious vehicles and bridges to reach other islands.
Grow crops on farms and process them into food or industrial products. Supply fertilizers to boost yields and build greenhouses to grow more advanced crops. Your population needs housing, clean water, electricity, healthcare, and household goods. Keep them happy and healthy, and they will reward you with Unity, a resource that lets you speed up construction, enact powerful edicts, and claim resources on the world map. Neglect waste management or let pollution build up, and diseases will spread.
Send your ship out to explore the world map. Discover new islands with resources to import, refugees to rescue, and allied settlements to trade with. Establish shipping contracts for recurring exchanges, or negotiate quick trades when you need something fast. Your ultimate goal is full self-sufficiency: launch rockets, build a space station, and mine asteroids for rare resources that make your colony independent indefinitely.
Copy and paste parts of your factory, or save entire layouts as blueprints to reuse and share. Use planning mode to lay out designs before committing resources. Design your own island in the map editor and play it or share it with others. Or switch to sandbox mode where all buildings and resources are free, perfect for experimenting and learning.

The game is amazing. You can play at your own pace, pause, test, fidget around with builds and adjust the game to your own personal preferences in terms of difficulity. The game has an excellent tutorial that doens't pop up and force you to read a bunch of stuff, but just makes the game flow more easily with a guided experience, rather than holding your hand and telling you what to do - it is optional to do the tutorial, but you'll eventually do it anyway and get some rewards for it. The game is also brutal, you can death spiral your base easily if you don't know what you are doing and it's both fantastic and really frustrating, but as always, you can load an autosave. As an avid Factorio player, this game is a fantastic game that does "the same thing" without doing the same thing. It tickles that itch and the terraforming is FANTASTIC. You aren't just placing down a miner and watching ore spawn from nothing, you are actually digging up the ground and moving it around, sorting it and then using the materials to build more. There are some bad thing, not being able to adjust a blueprint and then save overwrite the old blueprint, instead having to make a new one, but it's minor QoL stuff that the devs are probably already aware of.
If you like Factorio or, "Worker and Resources" you'll love this game. User Interface is a gem. The best I've ever seen. Tutorial and in-game information database is also the best I've ever seen. This is a very complex game but with all the information provided in game it's great. The "God Mode" is outstanding to learn the game and any peculiar things that come up. Blueprints are a breeze in any mode. Just remember to research them in game to use them. Graphics are always improving. The game is always improving. The recent train network system update transcended the game to one having the best train system out there imho. Soooo what's not like? Buy it.
The technology tree and limited resources ensure that there will be plenty of different objectives to pursue for a long time. In addition, from time to time you’ll have to solve a problem, whether it’s an energy crisis, a resource depletion, or a supply chain disruption. The game offers tremendous depth and replayability. [b]What I like[/b] [list] [*] The game about taking care of your people with help of industrial automation [*] Relatively realistic and grounded mechanics (instead of a scifi or fantasy setting) [*] Trains [*] Detailed buildings and vehicles [*] Many good maps (especially Dragon Trail) [*] Photo mode [/list] [b]What I wish[/b] [list] [*] Roads [*] Exploration and shipping needs some love [*] Prosedurally generated maps [*] High-resolution screenshots in photo mode [*] Key controls to tilt camera up/down [*] Native Linux support [/list] 9/10
Love this as much as Factorio and Satisfactory. They each have their good and bad sides but CoI is great because it adds the terraforming aspects which I love
自動化も工業化も素晴らしいが、このゲームの最も優れているところは土木だ。 平坦でない土地を削ってならし、鉱山を掘り、ガラしか出ないような山をほりぬいて新たなルートを作る。 もちろん大量の土砂と岩は広大な海洋を埋め立てる材料となる。 自動化ゲームはいくつもあるが、ここまで地形改造に拘ったゲームはそうそうない。 Satisfactoryと比べるなら敵対的クリーチャーがいないことや3Dの土台建築ができないことなどが気になる。 DysonSphereProgramと比べるなら柔軟な資源確保や運送方式の多様性のなさが気になる。 でも自動化で有名なこの2つにないのはやっぱり大規模土木工事だと思う。 掘ったら出てしまう土や岩や、人間が暮らす以上どうしても出てしまう廃棄物やあれやこれや 全部海洋投棄したっていい。文字通りここが君にとっての夢の島だ!
Great factory/colony sim. I have really enjoyed the progression. I really took my time and the game seems to reward you for being deliberate and slow. Thanks for catering to us slow pokes.
Have been addicted to this game since buying. Highly recommend if you like the genre of game!
What a huge improvement! I tried it for the first time a couple years ago, right after the kickstarter and it was almost unplayable. But now... Heck, it has proper tutorialization, the progress is really interesting, the UI works pretty well, the gameplay itself gives a lot of satisfaction and discovery.
This game has a highly addictive game play loop. After playing Oxygen Not Included, I've quite enjoyed this game. If you like city builders and want something different this is good alternative. I found the tutorial helpful to guide you through the game itself however I'd recommend going on YouTube and learning the mechanics of the game.
if you like factory games, this one will get you
