This is not a repost.

I dunno, you wait around 10 months for a patch, then 2 come along all at once. Yes, you've had Christmas, but what about SECOND Christmas?

This patch is mostly aimed at fixing some of the issues that weren't thrown up during the surprisingly extensive P17 testing, plus just a few shiny new features.

The most useful and helpful of these stems from a discussion that be summed up as follows.

  • uPnP doesn't work
  • Yes it does, shut up
  • No, look, I did all wireshark stuff, it doesn't work, and I'm smart and know technical words like 'TCP'
  • Look, it blatantly works, I'm running a server with it!
  • I don't think it works. I'll look up stuff. Wait, I configured wireshark wrong. But the game is doing a UDP broadcast when it should be doing a M-SEARCH multicast for the SSDP.
    --At this point I needed to do code things and read up on what any of those words meant--
  • The code has been changed. Try that.
  • It works!

So, basically, FC uses Lidgren, which is an industry-standard bit of networking code, and it follows the Microsoft/Novell recommendations which are WRONG.

TL;DR - uPnP should work on many MANY more routers than before.

So, on with the subject of networking - after a LOT of testing of the server, which MANY of you have joined, I did some further work, and have come up with a sweet optimisation for the itemdata for networking. Previously, this data was approximately 1 gigabyte/hour/user. It's now down to about 50 megs/hour/player.

And, sorry.

Mynocks will spawn on Slopes. YOU HAVE BEEN WARNED.

And the rest!

  • Fixed H and P erroneously opening up Help and Pause panels whilst searching. Hopefully didn't break anything else else.
  • All (known) Drag and Drop issues fixed
  • Added MMB to assign currently-hovered item in the Inventory to assign to currently selected HotBar slot.
  • Added Controls note to this effect.
  • Fixed issue where teleporting players took FOREVER to arrive - they should arrive within 2 seconds now!
  • Added teleport graphics for network players
  • Loads of handbook entries updated
  • Players will no longer be told to make a Lab if it's already researched and built.
  • Fixed Fast/Slow conveyor description when making a new world.
  • Updated bootstrap screen

  • Added a minor glow to Conveyor base, to allow you to see them in the dark
  • Added auto readout of Ore Veins for network players
  • Sign fix will now persist and also work over the network.
  • Blocked/Unblocked messages should now filter out much more strongly to clients from Conveyors.
  • Fixed debounce on MS output filters
  • Caught InstancedRender failure and displayed message
  • Fixed DiskThread.ProcessCleanUpQueue crash
  • Fixed readout issue for Cargo lifts when on Rapid difficulty.
  • Altered handbook to correctly show Rapid boost for Cargo lifts.

  • Fixed Mod upload button
  • Public server count now shown on the main menu
  • Minecarts rideable again!
  • Fixed texture assignment to Minecarts; Basic/Fast/Large should now correctly Tier with Loader Yellow, Green, Blue
  • Added directional chevrons on the Minecart Tracks. Might help a little.
  • "Crafted Item" filter now supports stacks of items, not just single items.
  • Magma Caverns are now lit for network clients.
  • MK3 WorkFloor Excavators should now spin SLIGHTLY slower, and not miss any block
  • Dyed Marble now just 1 shader darker by default.

Ohhh yes. Your CPH will now match your player, ARTHER and your SpiderBot, if you have the Dapper DLC Pack. I felt that the pack was a little weak, and wanted to find ways to let players show off all their hard-earned Skins. So with an amazing piece of work by Andy and Todd, you can now do this! (In a multiplayer game, CURRENTLY, the CPH will just reflect YOUR skin, but this will change)

Have YOU always wanted a Pink CPH?

"If the answer is no, you are sad, and I've no desire to speak with you further." - Sir Hammerlock.

And finally, I kept a visual diary of some of the glorious pics from the recent P17 multiplayer playthrough. Check 'em out if you're bored!

Onwards to Patch 18 - Rooms and Hydroponics.

Patch 17 is here, after 10 long months!

Main Features
  • The floaty-orange-button on some machine interfaces has been fixed.


Oh, you want more?

Major Features
  • 95%+ complete internal support for multiple languages
  • Complete replacement of UI API, giving support for double-byte characters, ie Arabic, Chinese, Indian, etc
  • Network bandwidth now as low as 5% of previous network usage. This should reduce 'packet loss' issues to a hopefully distant memory.
  • MK1, MK2 and MK3 Mass Storage StockPilers added (Allows you to limit the maximum number of an item in Mass Storage - thanks to SteveMan0 for
  • To celebrate the HUGE PERFORMANCE INCREASE in Multiplayer, there's a new Skin Pack available
  • This includes Santa (Yes, I missed the date on this a bit), Brazil, China, France, Germany, Italy, Russia, Spain, USA, Canada, Australia, The Nettherland
    and my favourite, the rainbow-themed Proud skin :
  • I plan to get translation support into the game for these languages over the next few patches - if you'd like to help out, head over to the Translation section on the forum!

Unreleased ('Patreon Only') Features
  • Orbital RailGun now buildable. Patreons only (until release of the Adventures Pack)
  • Orbital Railguns that save out at the Firing state no longer end up completely broken on reload
  • Fixed a really derpy code derp in the Orbital Railgun
  • Orbital RailGun Rings now cool at a rate of 1 degree per 30 seconds. (approx 120 minutes). A Freezon Canister will reduce this by another degree.
  • Orbital RailGun Rings currently require 100 resin per shot, per ring. (20,000 total Refined Resin) (TBD)
  • Orbital RailGun Controller needs 9 million power to fire. (TBD)
  • Destroyed CPH using Mutator Important CPH now causes all HiveMinds to grow. Yes. All.
  • Happy Feet Pandora's Box effect prototyped - need a name for the 'unhappy feet' equivalent.
  • Patreons will no longer be bugged to purchase the Frozen Factory expansion!

Networking optimisation details
  • Added SegmentEntity.Base.MaxNetworkSendDist - allows mod authors (and me) to not bother syncing specific machine types with distant network players. Defaults to -1 for no culling.
  • Conveyors now use this to aggressively cull unnecessary send data, further reducing the load on networked servers.
  • Improved server CPU readout to include machines, items and 'other'
  • Improved server disk CPU time monitoring
  • Item Updates have gone from ~600 megs/hour to ~20 megs/hour
  • Conveyors have gone from ~600megs/hour to ~1.3megs/hour
  • Servers will now consume approximately 1 gig per hour per 3 clients, depending on MANY factors. However, this is approximately 1/20th of the network bandwith of P16.
  • Server Network CPU time massively reduced; the server should now use approximately 30 minutes of a single thread CPU time per 24 hours of simulation.
  • TechAxe exclusive Patreon reward should now show up reliably for network players
  • Fixed overload of Build orders on large instanced entities on network servers
  • Saved approx 300 megs/hour by smartly discard dropped item data
  • Reduced item update footprint from to 320 bytes to 248 bytes
  • Collated total network usage of machines
  • Deeper introspection into UPDATE_CHANNEL usage
  • Massive optimisation to Minecarts' network efficiency (from upwards of 2500 bytes/update to 60 bytes/update)
  • Added deep and details /report to dedicated servers. This covers networking usage to the byte, and I'm gladly accepting reports from interesting and end-game and long-term servers!
  • removed 260 bytes/sec/player from SpiderBot updates
  • removed 100 bytes/sec/player from LOIC update
  • Knocked several seconds off of dedicated server loading time
  • Fixed issue where corrupted server information would break all public server accesses
  • Added per-machine network usage readout
  • Added PlayerData network usage calc

Quality of life improvements
  • Community fixes from SteveMan0, MadVandal and AgentMinty!
  • "Clearing Excavator" mission now supports Extractor naming (via Signs)
  • Build2Me orientation support for minecart track
  • Mad Vandal's fix for falling through lifts. Widens window for recognizing being on the lift to prevent spurious idling and keeps the feet out of the lift to prevent sliding through it.
  • Added Funelling. If you don't know what that is, it doesn't matter. If you do, you'll be all like 'oh wow that's clever, and I hope Dj shares some cool funelling analytics with me' - and you'd be right!
  • MK3 Workfloor Excavators now have DOUBLE (!) the range
  • Hooked up new IP query service
  • Signs should no longer be upside down
  • New loading screen! (remember, submit your amazing loading screens and I'll include them in the roster)
  • Added 'hint' when Mass Storage exceed 100 crates that perhaps, just maybe, you haven't designed your base quite right.
  • Stopped hinting and just telling that it's a bad idea when Mass Storage exceeds 1,000 crates.
  • Tunnel Nukers now spawn with much vigour during the start of the game, getting around a mistake in timing. This should mean Organic Rock is available to the exploratory player nearly instantly, and to regular players within the first hour.
  • Dead Overminds can no longer headbutt you.
  • Further support to 0.001% of my userbase - Linux should now accept chatline inputs, working around a Unity bug. Yup, FC supports Linux better than Unity does.
  • Hard Resin Detectors now show distance to resin AND distance of resin to base, as well as the last time the active Hive Mind gew.
  • Hard Resin Detector now shows encroaching Resin with audio and lights.
  • Made the Research Screen quite a bit less cluttered and more understandable.
  • 25 conveyor mission disables on Peak. Fixes MP issues.
  • Added 'You really shouldn't be using low texture detail' warning, due to streamers continually misunderstanding the slider.
  • Added slope conveyor mynock spawning to HiveEntity as well. Sorry.

  • Fixed T4Grinder/CCCCC power exploit
  • Advanced Conveyor Filters are now available using T1 resources, meaning that you should be able to start sorting things much, much sooner into the game.
  • Fixed a dead-end in the tutorial (yes, really!)
  • Increased Research Assembler internal power storage from 1500 to 3500
  • SpiderBot Power Cores now give 2500 power, up from 1000
  • Public server entries that cause the game to fall onto the second page now correctly allow access to the second page
  • Deep network clients should no longer be pestered about making a PTG
  • MK1 Workfloor Excavators now available earlier, and cost significantly less to craft.
  • Freezon-Boosting Liquifiers now works
  • Performance boost to Ablators
  • Fixed issue where Hiveminds that were 'contained' by many Ablators and Liquifiers wouldn't flip from 'shell' to 'tentacle' mode. This might mean that they're a little better at breaking out of containment. Sorry. #notsorry
  • Reduced Particle Compressor from 1024 to 512 pps
  • Boosted Geothermal output by 50% across the board.
  • Refineries now use 500 power per item, down from 1,000. MaxPower is still at 3,000 per vat.
  • Fluid now capped at 250 block/tick (down from 500) to attempt to keep build orders clear
  • ARTHER Releases from current recharge station if asked to dock with another
  • Threat Scanner should now indicate when all surface attacks are cleared, and will give CryoPlasm readout instead
  • MK2 Trenchers now extract 2x as much ore as MK1 Trenchers
  • MK3 Trenchers now extract 4x as much ore as MK1 Trenchers

Performance Improvements
I'm listing these as I continually get told I should be optimising the game instead of adding new features.
  • Plants on busy worlds will sleep for 10 seconds if they receive an error when accessing segments.
  • Fixed Lifts not using Instanced rendering.
  • Substantial performance improvements to rendering and CPU usage of Organic Rock.
  • Substantial render performance gains all over, using new Vis system

Bug Fixes
  • Fixed issue with available materials being reported as 2x
  • Fixed error in Overmind renderer
  • Plants on 'grassy' dedicated servers will now grow.
  • Fixed a generic issue with UV scrolling; this should mean no more flicking mynocks

  • Fixed issue with Workfloor Excavator error when unloading
  • Added another column for injections debug to prevent clipping stuff off the bottom
  • Per Mad Vandal, fix for threat scanners losing their yellow alert state.

About This Game

"In a world where early access and indie usually means abandoned, unfinished garbage, this game's post launch development is outpacing many AAA titles and companies."

"This really isn't the same game that I originally purchased anymore. With all the changes that have been made over that duration the game is so much more fun
now that there are machines to alleviate almost every large build annoyance that used to exist. The FALCORs, thieves, excavators, drills etc.. all did so much for
automation it's almost hard to believe I ever did that stuff manually before."

A Whole New Survival Experience...

FortressCraft has undergone a radical visual alteration, completely reworking the surface, along with a brand-new rendering system. On top of that, there is an enormous amount of work to make the game more understandable and accessible for new players. The combination of these two things should work towards making it feel like a fresh, new experience. Prepare for a new exploration and survival experience!

FortressCraft Evolved’s Survival Mode is a unique-blend of Voxel Landscapes, Tower Defense, Crafting, Logistics, Exploration, Combat and Assembly lines. Players begin by crash-landing on a strange alien world, left with only a small handful of starting machines. Using hand-held scanners they must locate ore resources, place down Ore Extractors and Conveyors to automate the raw material back to the Smelter; take the fresh ingots through multi-machine assembly lines, followed by researching new technologies that help them explore thousands of meters below the planet's surface.

An advanced HoloBase allows players to keep an eye on their factory which they must defend against waves of alien attacks with multiple tiers of missile and energy turrets. To survive they must continue to develop new and unique power systems, from solar energy to Jet Turbines, culminating in crafting an Orbital Energy Transmitter thousands of cubic meters in size, to beam power off-planet, and start the next phase of the game.

And all this with an enormous draw-distance, scalable gameplay engine that is equally at home on high-end or low-end computers, and full multiplayer support! This does not even factor in all that you can do in the Creative Mode whose only limits are your time and imagination. With an array of Super Build Tools and a high-resolution Custom Detail Block Workshop players can build anything and on a massive scale unseen in other games.

  • Experience the largest worlds ever seen in any computer game - ever!
  • Create a futuristic mining operation consisting of thousands of huge machines.
  • Full Tower-Defense style combat in a voxel universe.
  • Use hi-tech machinery to locate and process resources from thousands of meters away.
  • Explore thousands of metres vertically, overcoming ever-more difficult challenges.
  • Official Texture Pack and Mod Pack support
  • State of the art lighting and shadowing, utilising high resolution maps for machinery and environment
  • Innovative“Build to Me” Feature to facilitate rapid, accurate building
  • Shareable Creative Schematics
  • Super Build Tools allowing instant creation of primitive shapes
