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 800 units
- A good AI
- Customizable units (Rockets, bombs, drop tank, torpedo, trucks, half tracks, horses etc)
- A rank and experience system for the units, and the player
- Almost any country you want to play
- A unit editor (modify any unit you want)
- A tile editor (modify any tile you want)
- A map editor allowing you to recreate any battle of your choice (up to 300 x 300 hexes and above if your phone/tablet can handle it)
- Easy modding.
- Customizable strategic map.
- An entire Europe map
- An entire Pacific map
- An entire Eastern front map
- Branch campaigns for major countries.
- 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 + clouds (Optional)

- 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 !
If you have any suggestion, critic to make, send an email or leave a message on the discord. 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, share the game with your friends, knock yourself out !

sent out the soviet horde
I love this game! It feels like panzer corps in your pocket. My only small problem is that the bigger maps like Europe 1939 are unplayable ( app stops and phone is galaxy a11). I really wanted to play the wider European theater but this is still a very good game.
This is a top quality game! Initially simple but with real depth of strategy and customisation. Additionally the developer is very active on discord, I made a suggested change to the UI and he responded immediately with a test and a fix...... Great work all round
I have absolutely loved this game so far! I feel I have no reason to play on my computer because this game has everything I loved about those games (OoB, Panzer Corps) on mobile. Edit: Thank you for your quick response. The app description didn't lie, this game does have a cool developer ;) I played Panzer Marshal o...
Hope you can add sequel about ww3 nato vs warsaw pact in cold war gone hot.. maybe theatre of war maps in fulda gap, north germany, france, and middle east
