Hi I'm Valentin, young French developer of 21 years old. I started this game in December 2019 from scratch after playing my first wargame for a couple of hours.
Working alone on it with my brother who's responsible for the art.
This game features :

Over 700 units
Customizable units (Rockets, bombs, drop tank, torpedo, trucks, half tracks, horses etc)
A rank and experience system for the units, and the player
Any country you want to play
A unit editor (Create or modify any unit you want)
A tile editor (create or modify any tile you want)
A country editor (Create any country you want)
A map editor allowing you to recreate any battle of your choice (up to 300 x 300 hexes and above if your PC can handle it)
A fully functional steam workshop to upload your work to, and download other's
An entire Europe map
An entire Pacific map
An entire Eastern front map
A campaign for major countries, with a core-unit system (Keeping units between scenarios)
A supply line mechanics (Optional)
Blowing up or repairing bridges mechanics
Diving / going to surface, and spotting mechanics with submarines
Retreat, surrender, capture mechanics
A morale mechanics (Optional)
A season mechanics + weather mechanics (Optional)
No time limit to complete scenarios if you don't want to
Daily, or almost updates
A complete guide on Steam + official tutorials on youtube
A cool developper :))

Operation Citadel isn't just about the eastern front, and even less just about one battle. To be honest, all good names were taken and I could not think of one.
If you have a better idea, I would be happy to hear it, send me an email or drop by our discord !
The game should run just fine on pretty much anything. If not, you'll get a refund, but let me know so I actualize the requirements !
If you have any suggestion, critic to make, send an email or leave a message on the discord, or open a topic in the forum. You will ALWAYS be answered to.
And last but not least, if you like the game and want to support me, leave a positive / constructive review here on Steam, share the game with your friends, knock yourself out !

8.0.0

BREAKING CHANGES

Save files and scenarios generated by version 8 and above are not compatible with earlier game versions (7 and before). However, files from version 7 and before are compatible with version 8 and above.\n

\n\n\nHello everyone! \n\nYes, this is indeed one more major update for the game :)\n\nThere are two major highlights in this update, the first one being an actual in-game tutorial, with steps, to teach new players about game mechanics in a friendly way.\n\nThe second one is for the most creative of you out here, because this introduces new modding possibilities.\nThe game will now support Harmony out of the box, which lets you tweak the base game code, or write your own.\n\nThis should open up the world of possibilities to an unprecedented level, giving you the tools to build the mod of your dreams.\n\nThese new modding possibilities will however be unavailable on iOS and Android, simply because those platforms do not allow code injection from external libraries at runtime, whereas desktop platforms allow that.\n\nI cannot wait to see what you will come up with!\n\nAnd now, the full change-log!\n\n

ADDED

Brand new in-game Tutorial to make new players life easier.\n
Support for code modding using Harmony lib. This opens up a whole new world of modding possibilities, as you will now be able to write your own code to mod the game (this includes modifying the base game\'s code as well as adding your own). I have recorded a full tutorial that explains how to do that here .\n
Tooltip over the \'Continue\' button to provide information about what save is going to be loaded if you press it.\n
Localization of the game into Traditional Chinese.\n
The game is now fully playable through cloud gaming (GeForceNow).\n
Compression to save files, they now are 90% smaller (yes, 90%). This is the reason why the files no longer are backward compatible. Old files will still load fine.\n
New achievement for completing the new tutorial scenario.\n
New \'Library\' workshop tag for filtering mods.\n

\n\n

CHANGED

Multiplayer compatibility version.\n
App icon was changed to look more modern.\n
In-game mouse cursor to look more modern.\n
Main menu wallpaper was remade.\n
All Steam store artwork was reworked.\n
Steam store page trailer was updated.\n
Joining or creating a faction in the Diplomacy menu has been split in two for improved clarity. \n
Capturing units in campaign would not always add them to your reserve (in the case that you reached your max core units).\n
All save files are now properly trimmed instead of growing exponentially.\n
Cleaned up a lot of the code for modders.\n
Max SteamCloud files amount is now 100.\n
Max SteamCloud files total weight is now 1 GB.\n
Workshop tag \'Map\' has been removed and replaced by \'Scenario\'. Update your mods tags!\n

\n\n

FIXED

Modded heroes with custom graphics with wrong dimensions would prevent whole mod loading.\n
Borders will now be properly redrawn in real time (after any tile edit) in the Map Editor.\n
AI will no longer purchase paratroopers when there are no land VPs in the scenario.\n
AI will no longer purchase land units (infantry, tanks, etc) when there are no land VPs in the scenario.\n
Having a \'+\' char in your mod\'s name would prevent all sound effects or music clips to be loaded.\n
Sea Hurricane Mk I was not marked as carrier compatible.\n
Some units properties were not synced properly when loading a save file.\n
Minor details in Units Editor.\n
Lags when launching the game due to Steam Cloud saves being written to disk.\n
Countries not localized in the multiplayer real time lobby.\n
Real time hosting data transfer fixes.\n
Real time multiplayer now has proper re-sync (even for large maps) when a player goes out of sync and reconnects.\n
Leave room button would still be displayed even after being kicked out of a real time multiplayer room.\n
When trying to upgrade a unit, if that unit was not available to purchase for any reason, you could not upgrade it to itself.\n
Various localization fixes in different languages.\n
README and mod thumbnail files are now properly copied over to disk on iOS/Android.\n
