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 !

BREAKING CHANGE (mods):

\nTo all modders working on a mod with Harmony: some Mod variables have been renamed and their type has changed (from regular open field to private property). That \'small\' change as a result is effectively breaking all Harmony mods due to core mod variables being renamed. Please update the game Assembly ASAP and recompile your mod to fix.\n\n\n

ADDED

\n
    \n
  • Confirmation window when you try to delete a save file.\n
  • ModDataBag to PlayerSettings file.\n
  • Automatic dedicated chat channels for every languages the game supports.\n
  • Hot load support for real time multiplayer (game host can now load any save file mid game and that will be synced for every other players in the room).\n
\n\n

CHANGED

\n
    \n
  • In the multiplayer game hosting menu, both PBEM and real time buttons will be visible at all times and greyed out only when scenario is not properly configured.\n
  • Upon their creation, new mods will have new automatic data set in the Manifest.json (username, version...).\n
  • Playing with Harmony mods will now properly disable the \'achievement compatible\' setting.\n
\n\n

FIXED

\n
    \n
  • Transferring a unit to another player had no redeployment time (if sent to reserve).\n
  • Max FPS setting issues when saving/loading the player settings.\n
  • Chat was no longer autoconnecting when playing a scenario (regression from 8.0.4).\n
  • Real time multiplayer trying to raise events even when playing offline (regression from 8.0.4).\n
