World War 2 Simulation


If you are interested in the Historical side of WW2 and want a more detailed feel of the conflict where a mod touches on several areas then this is the mod for you. A complete overhaul brought to you by many talented modders of the community. Don't forget to check them out in the links below! ;)
Welcome to WWII Simulation Mod. Our current update / open Beta cycle is the first week of every month. Player Based feed back is the life blood of our mod so speak up if you have any concerns or issues in the Team Lead Discussion Areas. Thank you and have fun.

- More Historical Cities and VP of every country for more strategic assaults and defensive counterattacks!

- Historical Movement, Supply and Attrition. Plan your attacks accordingly!

- Updated Tech Tree with a few surprises along with more added in the future!

- Fortifications and other buildings are increased but costly, so use the resources and natural terrain available to you for a rugged defense!

- Use your army, airforce and navy to further your agenda! Now submarines are used more than before. Remember to escort your Battleships, Carriers and most important, your convoys!

- Updated Weather conditions for a more historical feel!

First off Thank you, 2nd could you consider Edward VIII for The Raj or for Britain as an option, and or allowing the editing of display figures (You know you select what image depicts your units) I play as the Raj alot, there should be a way to distinguish between Indian looking troops turbans, Gurkha and or "British pattern" troops

@uncharted aww that devastates me...I was truly looking to an interesting and expansive campaign as the British Empire...Now its just watered down and too generic. Perhaps take note from the ‘British Overhaul’ mod on here. That would be absolutely ideal for this mod. Their focus tree is massive, deeply intriguing, and provides a vast multitude of events, decisions. It overall gives the player a deep experience of guiding the Empire into a future of multiple possibilities. That mod is exactly what should be integrated into WW2 Sim. I’ve been dying to play a Britain scenario, but sadly not one overhaul does the British Empire any justice in the way of focus trees or events. They all seem to be consistently bland and too limited in variety...

Due to too many bugs that occured with all the included the modders decided to limit the amount of potential error sources 2 actually have a decent chance to fix the mod

@The Kaiser - i am afraid 2000 errors is what killed it. Were making our own right now

I took a look at the mod just now and noticed Grear Britain has a totally watered down focus tree compared to the screenshot posted here. I didn’t see any Battle or Cablestreet, spreading Fascism across the Empire, or anything that made me excited to start a British campaign with this mod. What happened? The current tree is very lackluster... :(

Brief news update. We have dev team members working on portraits, focus trees, naval movement issues, Land Doctrine / Engineering / Arty / Support Company tab additions, German Unit symbol pics upgrades (Hopefully to 4k), pill boxes, Division designer, etc, etc............all at various levels of completion. We are in no hurry, we want to do this right and ensure ouor quality control is in place for what we do release. If you folks have any feedback, comments, suggestions, wish lists, etc..........keep them coming, we appreciate them.
