What the developers have to say:

Why Early Access?

“We have been working on Factorio for over 4 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 may be increased upon 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 #152 - Team production challenge

Hello,
it has been quiet here the last week, Rseding is back in America, Albert is in Spain, and some pople have holidays. I have been programming until 9:30pm and then I realized I have to write Friday Facts, so it is going to be shorter today, although this happens quite often to me.

Testing the new multiplayer
We wanted to use 0.13 stable release as an opportunity to test the marketing benefits steam offers, but since a big part of the update is the introduction of the matching server, which might lure some people to try multiplayer, it needs to be really solid. Playing over an ip with a friend is working quite fine 0.13 already, but hosting a public game to which anyone with unpredictable network properties and computer speeds can join, requires a much more robust system. Since we don't want to put the rewritten multiplayer into our almost stable 0.13 and we don't want to wait with the update too long either, we decided that the 0.14 will contain only the multiplayer rewrite and it will be released as experimental very soon, and all the planned features for 0.14 will be just shifted to 0.15, which doesn't mean it should be delayed much.

All the planned features of the multiplayer rewrite are finished, including delaying input of slow players, dynamic changes of latencies of clients depending on their internet connection speed and more. So now is the time for hard testing and tweaking the details. I started using the great clumsy tool which helps me a lot to simulate different network problems locally, but being able to test it with the community will be invaluable.



The multiplayer testing map idea
We want to host a multiplayer map with a big player limit (like a 50) 24/7. People could drop in/drop out all the time and still have some fun even if they didn't play for a very long time. So we decided to make a scenario map where people will be assigned to small teams and each team will have it's own space, something like this:



The teams will get randomly generated production challenges, like produce x of something, research something etc. The first 3 teams to achieve that will get some points and the game is reset. The game could keep some global statistics of player performance and show some leaderboards as well. Scott is working on this and you should be able to test it soon hopefully.
If the server game manages to run good even under this load, the work on multiplayer would be finished to our satisfaction.
I also hope, that this will motivate people to make these kind of multiplayer scenarios for Factorio, because the possibilities are broad.

As always, let us know what you think on our forums.

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 the Scenario pack, available as free DLC. 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.

For an early-access game, its thoroughly built (puns, oh so many puns to be used), and is aggravatingly, tantilizingly addicting once you get a handle on the basics. the weapon types in-game are carefully structured (puns) and the tier system requiring the player to research multiple different roles to get to the machines and tools they need to progress to the next higher tier is absolutely insane. However, the game is severely lacking in enemy diversity, and once you figure out an efficient strategic defense (much like a(n) base-building RTS or Tower Defense play-type in that regard), the randomly placed A.I. hordes stand little chance and never change-up in terms of difficulty when facing serious opposition. Furthermore, the game, though futuristic in nature, has absolutely no means for crossing large bodies of water such as Rivers, lakes or oceans, so once you reach the end of whichever landmass you findyourself spawning on, have mined all of the surrounding resources and killed all of the enemy hordes and their bases, you are effectively stuck, for now. Hopefully in the near future, a form of Naval expansion will be added allowing for water-based resource collection and/or sea-based biological enemies (or even better mechanical cybernetic enemies? O.o). On a side note, the current state, biological life-forms and organic enemy production structures require more diversity and varying levels of difficuly when randomly spawned, but then thats just my opinion...... oh and hovercraft would be a nice touch also for late-game water-crossing..... I mean, this game does take place in some form of future right? So it would be reasonable to have some form of flyable hover vehicle thats fast and has no weapons, right?

Seems like a so small game, but it is a big masterpiece. I highly recommend this phenomal game, you can try the demo, but I love the multiplayer experience with friends. Campaign is very interesting too and it's just early access! Tons of mods supported by devs. Really worth the price.

Should you build a grand factory with buses, automation, trains and robots? YES.
Should you stock up on food (real life food obviously) first? YES.
Should you drink energy drinks? NO, those are gross, drink coffee.

Should you buy it? YES.

Great game if you like buiding stuff, defending stuff, blowing up stuff, burning stuff, building more stuff where you blew up stuff, making a giant train yard, blowing up more stuff and building stuff on it ashes.

*Pro Tip: Watch a lets play from someone like Arumba or Steejo and how they get started, it will make life easier.

How to describe this game in three words: confusing, inovative, and automated.
This game is so much fun. You spend hours just trying to get one simple machine to work, and when it's done, you feel very impressed with your work. I reccommend playing with other people(especially people who've already played the game a ton)can help a lot and make the game much, MUCH more fun.

It's kinda like.... Rollercoaster Tycoon meets Starcraft and some analytical math, and then they stay up all night together smoking crack cocaine. In a good way.

This game will eat your soul. Do not install this until you have a clear calender for at least 3 days. Stock up on snacks and drinks first too. Heck hire a maid/cook for the week. This "early access" game is more fleshed out than many full release games that have had a patch or two and that cost much more.

This game is early access, but not really. It's basically finished as far as I can tell. You start with a drill and a box. You have to feed your drill coal to keep it going. You craft some more drills and boxes. Then after a decent amount of iron and copper has been melted you can make automatic miners, belts and electricity, and this game becomes something truly mindblowing.

Your goal is to create the universes most effective automated factory, and by god you will try. Once you automate one thing, you can then automate another, and another, and eventually you will have a sprawling, massive factory that you didn't plan very well. It will bother you, so you'll make a new section of your factory, much more organized and effective. And then you'll make it bigger, and bigger and bigger, because by this point you realize that you need true mass production of everything if you want to get all the science packs produced, and your rocket built.

Then you'll look outside, or at your clock, and realize you haven't left your computer to eat, drink or sleep for five days. I'm not kidding, this game is worse than crack.

Factorio is one of my favorite games in my library. Campaign is an option but I'd prefer the free mode type thing. I have a few suggestions for the developer though,
-Add Boats they'd be great for getting over water
-Make different objectives rather then just launch a rocket into space
-More resources
-Different mining options rather then the two drills and by hand
As far as everything else, I'm fine with it. It's a great game totally worth the $20. I make youtube videos on me trying to beat it if you'd like to see me progress. My channel is RpMxLemon crs if your that intrested. I post every two days for now.

I used a poisonous gas to kill off an area of forest, so I could build a bunch of pumpjacks in its place, to get the crude oil I needed to produce the ammo for my tank.

10/10 would contribute to global warming again.
