Version 1.23 released. here are the changes.

Hi, we just made a new build of Production Line available. This takes the game to build 1.23. here is a full change list:

[version 1.23]
1) [GUI] Research button now pulses red if there is currently no research set.
2) [GFX] Changes to sunroof visuals so they leave the roof edge in place.
3) [Feature] Reversing Camera and TACC upgrades both now require a new 'camera' component.
4) [Bug] Loans can now never be negative, nor offered unless company estimated worth is at least $100k.
5) [Feature] Cars are now sold and priced in four different price-categories, with corresponding GUI changes.
6) [Feature] New features tab on the finance screen shows information on how popular each feature is at each price category.
7) [Bug] Fixed crash bug when deleting a slot while its configure imports window is open.
8) [GUI] Save game dialog now has a close button.
9) [GUI] It is now no longer possible to keep the conveyor placement GUI active after you hit the bulldozer button.
10) [Balances] Changes to the research times and value of some items.
11) [Tutorial] Added some extra explanatory tutorial windows and highlights.
12) [Bug] Bad conveyor message now no longer shows incorrectly with production slots.
13) [Bug] Fixed crash bug if quitting to main menu when cars with multiple features were in the showroom, then starting a new game, and autosave happening.
14) [Bug] Resources are no longer consumed for upgrades that are not selected for the current vehicle.
15) [Feature] Added new car feature & researchable technology: Touchscreen Interface.
16) [Feature} Added multi-language support.


The big changes here are the pricing model, where we now have price categories, and availability of research being different for each category, plus (in the long run) support for translations. At some point (hopefully tomorrow) I'll be doing a new steam guide explaining how the game will handle translated text, and its pretty simple to do, so hopefully if any members of the community are bilingual and able to help with translating the game, we can get support for other languages in there. It will probably make sense to have a separate forum for discussing language stuff too.

Interested to know what people think about the price-category changes. This is only phase one of 'fixing' the sales model, as right now potential customers have no defined income and thus the sales demand for every category (and body style) is the same. *that will change*.

Update to build 1.22 (Thursday 1st June)

Hi everyone! We just released a patch for the game. Please note that we have a pop-up notice on this one warning you that the build order for wheels HAS CHANGED. Lots of people said we had it wrong, so we changed it, but that *will* break your existing lines until you re-arrange them.
here are the changes:


  • 1) [Bug] Saving and loading no longer transforms all cars into sedans!
  • 2) [Bug] Fixed bug where pallets would sometimes disappear from supply stockpiles and other stockpiles.
  • 3) [Bug] Fixed bug wwhere speed buttons no longer highlighted to show current speed.
  • 4) [Bug] Fixed crash bug when researching powerplant efficiency.
  • 5) [GUI] Pop-up window now warns you whats changed if you delete a design currently being used by a production schedule.
  • 6) [GUI] Better tooltips to show information on the tech tree.
  • 7) [Tutorial] Some extra tutorial windows explaining game features have been added.
  • 8) [GUI] Tooltips are more readable now (different color).
  • 9) [GUI] Various minor GUI enhancements
  • 10) [Realism] Changed fitting order to Brakes, Wheels, Tires as suggested by almost everyone!
  • 11) [GUI] RollCage renamed to Body Shell.
  • 12) [GUI] Fixed inconsistent naming of Engine Control Unit.
  • 13) [Balance] Some late-stage technology is now slower to research.
  • 14) [Bug] Fixes to potential crash bugs and issues with resource delivery.
  • 15) [Feature] Added new researchable slot upgrade: Predictive Stock Control.
  • 16) [Bug] Fixed major timing bug that affected the export of finished components from manufacturing slots.


Don't forget to vote on the priorities. We have new car body styles arranged, but they will take a while. I plan on taking a look at making a better financial model for the next patch.

Update to version 1.21 (27th May)

Hi all! We just patched the game again today. here are the changes:


  • 1) [GUI] Research complete dialog now improved, more informative, more data.
  • 2) [Bug] The letter 'c' when typing no longer triggers a debug window.
  • 3) [Feature] You can now archive car model designs as long as you still have one design for each researched body style.
  • 4) [Bug] Fixed bug where the scroll buttons on the vehicle design browser window didn't work correctly.
  • 5) [Bug] Fixed crash bug when clicking a slot category then trying to place it on the map.
  • 6) [Bug] Fixed issue where the unlock status of car body styles was not cleared when quitting a running game.
  • 7) [GUI] Compact car thumbnail is now green.
  • 8) [Feature] Compact car body style now needs to be researched and unlocked.
  • 9) [GUI] Fit Wing Mirrors task now has a proper icon.
  • 10) [GUI] The car design window now shows a live preview of the selected model with its selected options.
  • 11) [Feature] You now cannot select mutually exclusive car model options (sunroof/panoramic, xenon/led etc).
  • 12) [GUI] Changed name and icons for some tech tree items to improve usability.
  • 13) [GUI] When placing slots, pallets are now drawn so its easier to recognise import and output slots.
  • 14) [Bug] Steam achievements should really work properly this time!
  • 15) [Feature] The value of the 'base car' now depends on the car body style.
    v16) [Bug] Fixed bug where right clicking to clear conveyor placement mode would also delete slots below the cursor.
  • 17) [GUI] New tile pop-up notices show you when you have connected a conveyor belt in the wrong direction.
  • 18) [Balance] Calculations for how high a car can be priced and how quickly it sells have been improved.
  • 19) [Bug] Fixed bug where supply stockpiles may refill at different rates depending on game speed.
  • 20) [Balance] Changes made to the way AI does research to improve game balance.
  • 21) [GUI] Features on the design details window are now sorted alphabetically rather than seemingly randomly!
  • 22) [Balance] Research speed slowed by 20%


I know we still have some balance issues, especially financially speaking. We do intend to get a system in place that models different markets for each car body style, along with markets at different price points, which will add some interesting decisions regarding pricing, and also make the game feel more realistic.
I'm also very well aware that some of the games mechanics need mroe iun the way of tutorial and explanation, especially the whole process of researching and unlocking upgrades. This patch improves that to an extent, but I knoww we need to go much further.

I hope you like the improvements made in this version.

Update 1.20 (Monday 22nd may)

Hi everyone!
First of all MANY THANKS for being a part of the early access for this game, I really appreciate it. If you don't already know, I'm a lone designer/programmer and feeling a bit overwhelmed with issues right now!. Anyway...

This update is 1.20 and it contains the following changes:

[version 1.20]
1) [Bug] Steam achievements should now trigger immediately, rather than on the next run of the app.
2) [GUI] Save games now store a small 256 pixel square snapshot instead of fullscreen (vastly speeds up save/load GUI).
3) [Feature] Loans now take into account existing debt, plus charge higher rates if you have one or more existing loans taken out.
4) [Bug] Fixed bug where the AI would stop noticing if your profit margin dropped below zero.
5) [Balance] Universal features are no longer worthless, but only command 50% of their original market value.
6) [Balance] A whole list of car features can now no longer ever be researched as universal by the AI.
7) [Bug] Fixed a very rare and seemingly random crash bug.
8) [Bug] Fixed bug where periodically the body style window on the slot details window could disappear and reappear.
9) [Bug] Changed display method for the efficiency chart to prevent a rare crazy visual glitch
10) [Feature] Complete overhaul of the way car designs are handled. Multiple car variants now supported, features set for each variant.

Now I *KNOW* some of you will be thinking WTF? about number 10, but this is in there because it was already 50% done when we wwent into EA so I couldnt patch the game without finishing it. I am aware that some people have crash bugs, and this is my #1 priority from tommorow morning (I need sleep!).
i also think I *may* have fixed some fo the crash bugs with this patch.

I am fully aware we need some serious tutorial love, and that the balance of the original release sucked! This release is MUCH better balanced.

So TL;DR:
Sorry if you experienced crashes and bad balance, this should help a bit, much more help on the way. Try out the new feature. Explanation coming soon...
