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 !

Overwhelmingly Positive (704 reviews)
Public Linux Depots:
  • Operation Citadel Depot : Linux [1.65 G]
8.0.2

ADDED

\n
    \n
  • Brand new main menu soundtrack, unfortunately was not ready in time for the release of 8.0.0 and the new art style, composed by the same artist.\n
  • Close/Minimize buttons to the tutorial window.\n
  • Loading wheel in the multiplayer button for when the game chats with the server.\n
\n\n

CHANGED

\n
    \n
  • Multiplayer compatibility version.\n
  • Manual (PDF), fixed incoherences and added Convoy section.\n
  • Increased online chat max slots from 100 to 500.\n
  • Improved clarity regarding landings in the tutorial (unit needing to be located on a tile adjacent to the tile where you want it to land).\n
  • Login, register, password recovery, and account deletion buttons in the multiplayer menu will now be disabled whenever the game chatting with the server (to prevent request spamming that does nothing but waste everyone\'s time and resources).\n
  • When you override the manpower of a tile in the map editor, and when that tile became occupied during the game, the regular \'occupied\' value of the tile (found in the Tiles editor) would be used instead of calculated from the override you chose. Now, an automatic override of the occupied value is calculated, as 1/5th of the value, to respect the base game ratio between occupied and non occupied tiles.\n
  • Land and naval mines are now allowed to be deployed on victory points, as long as they are not reinforcement tiles.\n
  • Many more properties are now exported to CSV in the Units editor.\n
  • Code clean up for modders.\n
\n\n

FIXED

\n
    \n
  • Upgrading/Downgrading unit error message thrown in real time multiplayer.\n
  • AA units were restricted from targeting enemy land units further than 1 tile away, even when they attack range stat was set to any number higher than 1.\n
  • Steam Cloud save files were not available when trying to host a real time online game.\n
  • Korean, Japanese, and Chinese number order issue with units naming.\n
  • Incompatibility between the mountaineer and truck/mechanized option, when trying to move on a mountain and having both options active on your unit.\n
