What the developers have to say:

Why Early Access?

“We have been working on Factorio for over 5 years. The game is very stable and is highly optimised for prolonged gameplay and creating huge factories. We have sold over 110,000 copies on our website, and we feel now is the right time to release to a wider audience.”

Approximately how long will this game be in Early Access?

“Our plans for release come as part of an ongoing process, and we are constantly adding new features and content. When we feel the game is complete we will release the full version, and our current estimate is that this will take 8-12 months.”

How is the full version planned to differ from the Early Access version?

“In the full version we hope to have a polished GUI, a multiplayer matching server, integration of mods for players and servers, and a number of other finishing touches and additions to the core gameplay.”

What is the current state of the Early Access version?

“The game has a very strong content base, rich with interesting mechanics and features. Many players report they are still having fun on their maps even after hundreds of hours of gameplay, alongside multiplayer support, and a dedicated modding community.”

Will the game be priced differently during and after Early Access?

“The price will not increase after release from Early access.”

How are you planning on involving the Community in your development process?

“The community is a vital part of our development process. We announce any planned features far in advance so we have time to read peoples' opinions and comments, and for us to discuss the different points of view players may have. Community suggested ideas are commonly brought up in team discussions, and we value highly the input each individual player can have.”

Friday Facts #243 - New GUI tileset

The new GUI tileset
The process of the GUI re-design is moving slowly but steadily. By making new mockups, re-thinking old mechanics, and with the proper feedback from a different range of people, the parts are falling into place.

I'm starting to feel very confident with the actual general contrast and font sizes. Also the conversion from high resolution to normal resolution is working just fine. These subjects are very important to move forward with.

Below you can see a demo of the current state of the new GUI. Not all the widgets are shown yet, but this document is helping us a lot in order to define the future elements.Seeing the big picture makes it much easier to tweak them altogether with a better coherence and consistency, not to mention for testing any kind of font, specifically non-latin characters sets, a subject that I personally have not paid too much attention to yet.

This document is being used also to create the general tileset and see how it behaves in the engine. This is a work in progress, and we are tweaking details constantly. Many things will change during the process. Overall here you can see a sneak peek of the Factorio GUI to come.

I want to also mention that we are actually taking care of the 8% of the population who has some sort of color vision problems. This subject is still very new for us, but we are without a doubt researching solutions to different conditions.

New office
The moving to the new office went better than expected, and with the new carpet, it feels cozy.

We are currently using approximately 40% of the available space, so there is a room for growth if needed.

Let us know what you think on our forum.

About This Game

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 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. However this heavy exploitation of the planet's resources does not sit nicely with the locals, so you will have to be prepared to defend yourself and your machine empire.

Join forces with other players in cooperative Multiplayer, create huge factories, collaborate and delegate tasks between you and your friends. Add mods to increase your enjoyment, from small tweak 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 freeplay scenario, there are 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, and even add your own custom script to make for interesting gameplay.

Discount Disclaimer: We don't have any plans to take part in a sale or to reduce the price for the foreseeable future.
