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 !
