Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

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?

“No, the price now is the final price.”

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 #282 - 0.17 in sight

Read this blog post on our website.

The release plan
This week was the time to close and finish all the things that will go to 0.17.0.

Not all of the things that we originally planned to be done were done (surprise), but we just left any non-essential stuff for later so we won't postpone the release any further. The plan is, that next week will be dedicated to the office playtesting and bugfixing. Many would argue, that we could just release instantly and let the players find the bugs for us, but we want to fix the most obvious problems in-house to avoid too many duplicate bug reports and chaos after the release. Also, some potential bugs, like save corruptions, are much more easily worked on in-house.

If the playtesting goes well, we will let you know next Friday, and if it is the case, we will aim to release the week starting 25th February.

After release plan
Since there are a lot of things we would like to do before we can call 0.17 good enough, we will simply push new things into the 0.17 releases as time goes on. Even if 0.17 becomes stable in a reasonable time, we would still push things on top of it. We can still make experimental/stable version numbers inside 0.17. Most of the things shouldn't be big enough to make the game generally unstable. I've heard countless times a proposal to make small frequent releases of what have we added, this will probably be reality after 0.17 for some time.

The smaller releases will contain mainly:
  • Final looks and behaviour of new GUI screens as they will be finished.
  • New graphics.
  • New sounds and sound system tweaks.
  • Mini tutorial additions and tweaks.

This is actually quite a large change to our procedures, and there are many ways we will be trying to maximize the effectiveness of smaller and more regular content updates.

The GUI progress
There are several GUI screens that are finished. Others (most of them) are just left there as they are in 0.16. They are a combination of the new GUI styles and old ones. They sometimes look funny and out of place, but they should be functional.



Blueprint library
The blueprint library changes have been split into several steps. The reason is, that there was a big motivation to do the integration with the new quickbar (final version introduced in FFF-278) in time for 0.17.0, while the other changes can be done after. The thing with the quickbar is, that it is quite a big change to one of the most used tools in the game and people generally don't like change even when it is for the better. To minimize the hate of the change, we need to "sell it properly". By that, we should provide as many of the positive aspects of the new quickbar at the time of its introduction.

So the change that is already implemented and working for 0.17 is the ability to put blueprints/books into the quick bar in a way that the quick bar is linked directly to the blueprint library window, so you don't need to have the physical blueprint items in your inventory. The other change is, that picking a blueprint from the blueprint library and then pressing Q will just dismiss it, instead of silently pushing it to your inventory. This works the same as the clipboard described in FFF-255. You can still explicitly insert the blueprint from the library to an inventory slot, but if you just pick it, use it, and press Q, it goes away.

In addition to this, other changes related to the blueprint library will follow soon after 0.17.0. The first thing is the change of how the GUI looks:



We will also allow to switch between grid and list view. It mainly provides a way to nicely see the longer names of the blueprint. We noticed that players try to put a large amount of info about a blueprint in its name, so we are planning to add a possibility to write a textual description of the blueprint.



The last big change is to allow to put blueprint books into blueprint books, allowing better organisation. Basically like a directory structure. Whenever a blueprint/book is opened, we plan to show its current location, so the player knows exactly what is going on.



The hand
Has it ever happened to you, that you have robots trying to put things into your full inventory, while you pick an item from it to build something, and then you just can't put it back, as the diligent robots just filled the last slot in your inventory by whatever they are trying to give to you? Wood from tree removal is the most frequent thing in my case.

This was annoying in 0.16 from time to time, but with the new quickbar, it started to happen even more, as now, you have only one inventory, and no reserved slots in the quickbar. To solve that, we just extended the "principal" of the hand. When you pick something from the inventory, the hand icon appears on the slot. As long as you hold the thing in your cursor, the hand stays there, and prevents other things from being inserted there. This way, you should always be able to return the currently selected item into your inventory as long as you didn't get it from external source like a chest.


The hand is protecting the slot from the robots.

Terrain generation updates
Everyone has different opinions about what makes a good Factorio world.I've been working on several changes for 0.17, but the overarching themehas been to make the map generator options screen more intuitiveand more powerful.

This was talked about somewhat in an earlier FFF (FFF-258) regarding ore placement,but since then we found more stuff to fix.

Biter Bases
In 0.16, the size control for biter bases didn't have much effect.The frequency control changed the frequency, but that also decreased the size of bases,which wasn't generally what people wanted.

For 0.17 we've reworked biter placement using a system similar to that with which we got resource placement under control. The size and frequency controls now act more like most people would expect, with frequency increasing the number of bases, and size changing the size of each base.



New preview UI showing the effects of enemy base controls.In reality the preview takes a couple seconds to regenerate after every change,but the regeneration part is skipped in this animation to clearly show the effects of the controls.

If you don't like the relatively uniform-across-the-world placement of biters,there are changes under the hood to make it easier for modders to do something different.Placement is now based on NamedNoiseExpressions "enemy_base_frequency" and "enemy_base_radius", which in turn reference "enemy_base_intensity".By overriding any of those, a modder could easily create a map where biters are found only at high elevations,or only near water, or correlate enemy placement with that of resources, or any other thing that can be expressed as a function of location.

Cliffs
We've added a 'continuity' control for cliffs. If you really ike mazes of cliffs, set it to high to reduce the number of gaps in cliff faces.Or you can turn it way down to make cliffs very rare or be completely absent.



Changing cliff frequency and continuity. Since cliffs are based on elevation,you'll have to turn frequency way up if you want lots of layers even near the starting lake.

Biome Debugging
Tile placement is based on a range of humidity and 'aux' values(humidity and aux being properties that vary at different points across the world)that are suitable for each type of tile. For example: grass is only placed in places with relatively high humidity, and desert (not to be confused with plain old sand)only gets placed where aux is high. We've taken to calling these constraints 'rectangles',because when you plot each tile's home turf on a chart of humidity and aux,they are shown as rectangles.

It's hard to make sense of the rectangles just by looking at the autoplace code for each tile, so I wrote a script to chart them. This allowed us to ensure that they were arranged as we wanted, with no gaps between them,and with overlap in some cases.


Rectangles.

Having the humidity-aux-tile chart is all well and good, but doesn't tell the whole story,since tile placement also depends on a noise layer specific to each tile type,and could also influenced by user-adjustable autoplace controls (e.g. turning the grass slider up).So to further help us visualize how humidity, aux, tile-specific noise, andautoplace controls worked together to determine tiles on the map,there are a couple of alternate humidity and aux generators that simply vary themlinearly from north-south and west-east, respectively.


Using 'debug-moisture' and 'debug-aux' generators to drive moisture and aux, respectively.

This map helped us realize that, rather than having controls for each different type of tile, it made more sense to just control moisture and aux (which is called 'terrain type' in the GUI,because 'aux' doesn't mean anything).


Sliding the moisture and aux bias sliders to make the world more or less grassy or red-deserty.

A pet project of mine has been toput controls in the map generator GUI so that we could select generatorsfor various tile properties (temperature, aux, humidity, elevation, etc) atmap-creation time without necessarily needing to involve mods.This was useful for debugging the biome rectangles, but my ulteriormotive was to, at least in cases where there are multiple options,show the generator information to players. A couple of reasons forthis:
  • It was already possible for mods to override tile property generators via presets, butwe didn't have a place to show that information in the UI.So switching between presets could change hidden variables in non-obvious waysand lead to a lot of confusion.
  • I had dreams of shipping alternate elevation generators in the base game.

Water Placement
For 0.16 I attempted to make the shape of continents more interesting. Some people really liked the new terrain, or at least managed to find some settings that made it work for them. Others called it a "swampy mess". A common refrain was that the world was more fun to explore in the 0.12 days.

So in 0.17 we're restoring the default elevation generator to one very similar to that used by 0.12. Which means large, sometimes-connected lakes.

The water 'frequency' control was confusing to a lot of people including myself.It could be interpreted as "how much water", when the actual effect was to inversely scale both bodies of water and continents, such that higher water frequency actually meant smaller bodies of water.So for 0.17, the water 'frequency' and 'size' sliders are being replaced with 'scale' and 'coverage',which do the same thing, but in a hopefully more obvious way.Larger scale means larger land features, while more coverage means more of the map covered in water.

New Map Types
In order to ensure a decent starting area, the elevation generator always makes a plateau there (so you'll never spawn in the middle oft he ocean), and a lake (so you can get a power plant running). Depending on what's going on outside of that plateau, this sometimes resulted in a circular ring of cliffs around the starting point,which looked very artificial, and we wanted to reduce that effect.

In the process of solving that problem I created another custom generator for debugging purposes.This one simply generated that starting area plateau in an endless ocean.I don't actually remember how this was useful for debugging, but at one point I directed Twinsen to look at it to illustrate the mechanics behind generating the starting area.

The rest of the team liked that setting so much that we're making it a player-selectable option. So in 0.17 you'll get to pick between the 'Normal' map type, which resembles that from 0.12,and 'Island', which gives you a single large-ish island at the starting point.There's a slider to let you change the size of the island(s).



Maps with multiple starting points will have multiple islands.


PvP islands!

And speaking of scale sliders, we're expanding their range from ± a factor of 2 (the old 'very low' to 'very high' settings)to ± a factor of 6 (shown as '17%' to '600%'). Previously the values were stored internally as one of 5 discrete options,but as the recent terrain generation changes have made actual numeric multipliers more meaningful in most contexts(e.g. the number of ore patches is directly proportional to the value of the 'frequency' slider,rather than being just vaguely related to it somehow),we're switching to storing them as numbers.This has the side-effect that if you don't mindediting some JSON,you'll be able to create maps with values outside the range provided by the GUI sliders.

Mods will be able to add their own 'map types' to the map type drop-down, too. If you really liked the shape of landmasses in 0.16 and want to be able to continue creating new maps with it, please let us know on the forum.

High-res accumulators



The design of the accumulator has been always good. The 4 very visible cylinders, looking like giant batteries, Tesla poles and the electric beams perfectly telegraphed its function in terms of style and readability. That’s why for the high-res conversion we were very careful about keeping this entity as it was.

The only thing that was a bit disturbing (for some) are the poles crossing to each other when more than one accumulator is placed in a row. So we decided to fix it (or break it). The rest of the work was making the entity compatible for the actual look of the game. But in essence accumulators are still the same.

Friday Facts #281 - For a Few Frames More

Read this article on our Website.

For a few frames more
Previously on Factorio Friday Facts (#264): "No wonder, scenes heavy on smoke or trees can tank FPS, especially in 4K. Maybe we should do something about that..."

Sometimes, it's just a bug
Writing technical Friday Facts helps me to summarize what I know, look at problems from a different perspective, and sometimes try to answer questions I haven't even thought of asking before.

For example, I made the overdraw visualization just for screenshot for FFF-264, and while writing the FFF I didn't analyzed them. Just after the blog post was released I looked at it and started thinking - why does smoke create such a huge overdraw blob when it is just barely noticeable in game view? Well, it turned out it was largely due to a bug. Some time ago we optimized smoke particles so that they are only updated once every 120 ticks (2 seconds), and its animation (movement, scale and opacity) is interpolated during drawing.

Thing is, particles are destroyed only during their update, if the lifetime of a particle ended somewhere in middle of the 120 tick window, the particle would be still drawn until destroyed. Because smoke fades away and scales up during its lifetime, it would be drawing itself fully transparent over a large area. Making the smoke particle not draw itself past its lifetime reduced number of particles being drawn by 15%, and reduced the number of pixels being rasterized even more. Additionally, particles below 2% opacity don't really seem to add anything to the final picture, so we can safely not draw those to get little extra boost.

Turret range visualization optimization
Probably only a very small number of our players actually run into this issue during normal play, but it is simple problem that we used to learn more about how to use GPUs more efficiently.

Turret ranges in the map view are rendered as opaque geometry (no sprites) to an offscreen buffer which is subsequently drawn semi-transparently to the game view. This makes the turret ranges blend into single solid shape of the same color. Every pixel is written for each turret in range, but if it is written once, subsequent writes are unnecessary.

We had two ideas how to optimize this. First, enable stencil test, so that pixels can be written just once. The second, pass a list of turrets to the GPU and test if each pixel is in range of any turret using a pixel shader. The stencil test idea yielded about 3x speed-up in our extreme test cases (20x20 turrets) which was not good enough - if your GPU had a problem with 3x3 grid, it would have problem again with 9x3 grid, which is not such a preposterous setup to have. The pixel shader idea turned out to be mixed bag - if the entire screen was in range, the shader would be lightning fast, but as soon as there were pixels outside of range, which meant shader had to iterate through entire list of turrets to figure out none covers it, performance started to drop off rapidly. In the worst case, it would be worse than without optimization.

Jiri came up with idea to do prepass, in which we would render the geometry into a much smaller buffer (let's say 16x smaller in both width and height) and then in turret range shader we would check if a pixel is definitely in range (pixel in prepass buffer is fully opaque), definitely out of range (pixel in prepass buffer is fully transparent) or we don't know (pixel in prepass buffer is semi-transparent due to linear filtering) and we need to the pixel against the turret list. He did that and performance improved slightly, but not as much as we hoped for. After further investigation we found out the GPU really doesn't like the early exit in the pixel shader. Jiri managed to remove it by rendering all the certain cases first, while marking uncertain pixels in stencil buffer, and in another pass he would run the turret range shader on just stenciled pixels. This solution ended up being up to 20x faster in cases that were too slow with the un-optimized solution, but as you would zoom out more and there were more turrets covering less pixels on screen, the orginal solution would become better. So we turn on the optimization only when you are zoomed in enough.

By the way, artillery ranges suffered from the same problem in early 0.16 versions, but they are so large it was good enough for us to test if entire screen is in range, and draw just single fullscreen rectangle in that case. Turrets were very likely to cause problems on low-end GPU even when not covering the entire screen.

GPU performance
As always, the root of all performance degradation is memory access. Since we mostly do just simple sprite drawing, the GPU has to read pixels from a texture, and blend it into a framebuffer. Which technically means reading pixels from another texture, doing some simple maths with the two values, and writing the result back. GPUs are designed to do this on a massively parallel scale and are optimized for high memory bandwidth while sacrificing memory latency. The assumption is you'll want to do at least a little bit of maths on the colors that you fetch from textures, to give the resulting image some dynamic detail. Every GPU core can then have many scheduled tasks and switch between them as the current task starts waiting on some memory operation to finish.

When you don't really do any math to add dynamic details, and all detail comes from drawing more layers of sprites, the GPU cores quickly reach their limit of maximum tasks and every one of them is stalled by a memory access. That is not to say we don't hit memory bandwidth limits on some hardware. For cases where we do hit memory bandwidth limits, we added an option to do rendering in 16-bit color depth (as opposed to the normal 32-bit). This option is intended for old GPUs and integrated GPUs.

An obvious way to improve this is to shade less pixels. This is something I mentioned before in FFF-227 by splitting tree shadows from tree trunks to remove large areas of completely transparent pixels. This can be improved further by drawing sprites not as rectangles but as generic polygons that envelope sprites such that most of the fully transparent areas won't be rasterized. This is something we will probably do for the most problematic sprites (trees and decoratives).

Another way to reduce the number of shaded pixels is to simply to render in lower resolution. We actually do this for lights for a long time already, but it could be used for other effects that don't have important high frequency detail - for example smoke. Ultimately, some GPUs are not cut for rendering the game in FullHD resolution no matter what (for example Intel HD Graphics 2500 or multimedia cards like GeForce GT 710 and Radeon HD 6450 come to mind), so they would benefit from an option to render the game view in lower resolution with native-resolution GUI overlay.

In FFF-227, I also mentioned mipmaps - downscaled copies of textures that are used when a texture is being scaled down. This helps to better utilize the caches on GPU, and therefore reduce the need to access main VRAM. We already used mipmaps for trees and decoratives in 0.16, but paradoxically some people had performance issues when they had mipmaps enabled. The problem is, in 0.16 we always use trilinear filtering for mipmapped textures. That means when you want to draw as sprite at 75% scale, the GPU will get a pixel from the 100% scale mipmap, and the 50% scale mipmap and average them to get the pixel for the 75% scale version. The access to two different mipmap levels would make things slower. In the new rendering code, we are able to control this, so for sprites that are likely to cause performance issues (for example smoke) we can just fetch pixels from the closest finer detailed mipmap.

Texture compression
GPUs natively support block compressed formats - the texture is divided into 4x4 pixels (or possibly different sizes in formats that are not commonly supported by desktop GPUs) and each block is compressed into a fixed number of bytes. Commonly supported formats on desktop GPUs are BC1-7. Most interesting to us, are:
  • BC1 (used to be DXT1) - Intended for RGB without alpha (or 1 bit alpha) with uses 4 bits per pixel (as opposed to the 32 bits raw RGBA uses).
  • BC3 (used to be DXT5) - Uses 8 bits per pixel - same format for color as BC1, but uses 4 extra bits for the alpha channel.
  • BC4 - Stores just a single color channel in the same format as the alpha channel in BC3 is stored (so 4 bits per pixel).

These formats work pretty well with normal textures, but not so well with 2D art that contains a lot of small detail. With our art it is not so bad as long as sprites are static, but as soon as we apply the compression on animations, even tiny changes in individual pixels results in larger changes in blocks that contain them, and the resulting animation ends up looking very noisy.

Uncompressed vs. BC3 compression

Awesomenouts developers described this in their blogpost on how compressed formats supported by GPUs work, what kind of artifacts it creates in their art, and what they do to improve quality. They store their sprites in a slightly higher resolution (for example 41% larger width and height) to spread the large frequency detail more apart. This makes compression less efficient but still worth it. The problem is, we can't really do this as it makes our sprites look pretty bad and blurry.

During our initial experiments with compression, we deemed the quality of compression to be too low. In addition to that it somewhat slowed down the game startup as we built sprite atlases in an uncompressed format first and compressed them at the end of the sprite loading process. I left the 'Texture compression' option in, for people who really needed to use it, and it would compress only the sprites that usually blend over some other graphics (like color masks, shadows and smoke).

The most commonly used image or video compression formats (like JPEG or H.264) exploit the fact that human vision is actually pretty bad at recognizing colors and is much more sensitive to changes in brightness. Instead of RGB color space they use of color space based on luma (brightness) and chrominance (color), and apply better quality compression to the luma component and lower quality to color components, resulting in a very high quality image to the human eye. Some smart people thought this technique could be used to improve the quality of GPU block compression formats.

One of the ideas is YCoCg-DXT compression which uses BC3 as an underlying format and stores luma in alpha channel for higher quality compression and chrominance in RGB channels. Pixel shaders that use these textures need to do just a little bit of math to convert colors from YCoCg color space to RGB. We tried to integrate this (using separate BC4 compressed texture for alpha channel) and were pleasantly surprised by the result. You probably won't notice artifacts unless you zoom-in a lot and look for them. In fact, two weeks ago I enabled texture compression by default (and didn't tell anyone), and whenever I ask somebody on the team if they disabled it, they say they didn't know it was turned on. So I am pretty happy about that. The small downside is the need to use two textures (BC3 + BC4) resulting in 12 bits per pixel, but the best thing is, despite the pixel shader having to fetch from 2 textures instead of just one, the GPU is able to render up to twice as fast due to caches being able to fit more pixels in compressed formats than in raw formats.

Luckily the paper contains the pixel shader code for compressing to this format on GPU, so we just had to adapt our sprite loading code to efficiently utilize GPU for compressing sprites as they are being loaded, so that the fact that we are compressing sprites during startup doesn't make the game load slower.

In 0.17, the texture compression graphics setting is changed to a drop down list containing 'None', 'High quality' and 'Low quality':
  • High quality will use the custom YCoCg-DXT compression and will be the default on most computers.
  • Low quality will use BC3 and is intended for use only on really weak GPUs.
There shouldn't be any reason for you to disable compression, the option to do so is there mainly just in case some technical issue appears. Compression is applied to all sprites except the GUI, which needs to be as crisp as possible. Also, regardless of the texture compression option, shadow sprites will be always compressed using the BC4 format.

Uncompressed vs. High quality compression vs. Low quality compression

After we added the high-res worms, biters, and spitters, VRAM usage rose up to 3.5GB (with high-res enabled, obviously) when no compression (even the shadow one) was applied. Compressing just shadows decreased VRAM usage to 0.16 levels of ~2.5GB. With high quality compression enabled, VRAM usage of sprite atlases currently is ~1GB (without mipmaps). This means, vanilla should be perfectly playable in high-res on GPUs with 2GB VRAM, and in combination with texture streaming these GPUs should be able to keep up in high-res even in cases when mods add a lot of new sprites. High-resolution sprites were originally intended for players with the most powerful computers, but in 0.17, they'll essentially become new standard. The goal is to eventually remove the 'low' and 'very-low' sprite resolution options, as 'low quality' texture compression on normal sprites + texture streaming should be able to run even on GPUs with very low VRAM sizes.

Side note: I mentioned there are 7 BC formats. BC7 is intended for RGB or RGBA textures, and has potentially much better quality than BC3 with the same compression ratio. The problem is, the format was introduced with DirectX 11, so it is not supported by DirectX 10 class hardware, and it is not available in OpenGL on macOS. The second problem is that it takes a very very long to compress something into this format, because the compressor has to try out a large number of configurations for each block to find the one that yields the best quality. Since Factorio is kind of outlier in that its art is distributed in bunch of PNG files instead of having everything neatly packaged so that graphical assets can be loaded directly to the GPU, without any transcoding to a different format or dynamically building sprite atlases, we require a real-time compression solution. We are not eager to change how the game is distributed too much, for one having everything in separate files makes updates reasonably small when we change some of them, and having vanilla data completely open makes it easier for people to mod the game.

Now look at these graphs
We took some benchmarks of extreme scenes. The first one is on save from public Clusterio event last year. Twinsen sent me the save, because he was getting framerate drops in the middle of large steam turbine array. The second one is save from a bug report. I choose the save because it has rails going though forest and because I could really get low FPS on it even in 0.16, I used map editor to carpet the ground with grass decoratives.

We tested on GPUs with 2GB or 1GB of VRAM, that we have in the office. Benchmarks on desktop GPUs ran on single PC (we just swapped GPUs between runs) - Intel Core i7-4790K, 16GB RAM, Windows 10. We measured the time a frame was being processed by GPU, for 1000 frames, and averaged out the results. We benchmarked against the 0.17 build from before GPU-side optimizations were implemented, unfortunately we don't have a way to capture GPU timings in 0.16. Tests ran in FullHD resolution (1920x1080) with high resolution sprites enabled, with a graphic configuration that I believe to be the best for rendering performance. For old build: Mipmaps, Atlas specialization, Separate lower object atlas, Texture compression options enabled, Video Memory Usage set to All. And equivalent configuration for the new build, except for using the new high quality compression option.

We also included a result from one high-performance GPU (GeForce GTX 980 4GB), but this was ran in 4K resolution (3840x2160) as opposed to FullHD.The benchmark of Intel HD Graphics 5500 was ran on a laptop with Intel Core i7-5600U and 16GB RAM, and used Low quality texture compression instead. We also included results with 16-bit color depth enabled.







Times were measured in milliseconds. Lower times are better, and for 60 FPS, a frame needs to take under 16.66ms.

If you are interested in how GPUs work more in-depth, Fabian Giesen wrote a nice series of articles on the topic.

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.
