PROGRESS UPDATE
After several months of hard work, I believe is time to show you a report of the project progress so far. I hope you find it interesting.
CAMPAIGN: Half of the scenarios are complete, including my testing of them. I expect to increase the speed of the creation process.
The briefings need to be improved as my english sucks and I am not a good writer, but for now I am focused to finish all the scenarios.
UNITS: 560 new units so far, including brand new ones (more than 100 so far and more to come) and special camouflages. Regarding the latter, I tried to be as historical accurate as possible depending the battle and the date it took place. I spent hours and days reading books and websites to gather as more as possible, I can proudly say the 90% of the camos you would see in the mod are completely accurate

.
Still I have some work to do with the naval units, there are more than 15 new ones so far, most of them need some improvements. More to come yet.
SOUNDS: More than half of them are finished, I have a lot of ideas but I will leave them to final stage of my work. Yes, you will hear PPSH´s, PTDR´s, Mosin´s, MP44´s, etc.
UI: The basic idea is finished, all traces of "werhmacht styles" have been replaced with soviet ones (I used some Bebro´s work). As I said before, very basic work, I expect to improve it at the end of the project.
At this point of the development, I think I need some feedback from the community, so I ask for volunteers to do some "alpha" testing of my advances so far. Anyone who is interested please send me a PM, by the next week I will have a fully working alpha version of the mod.
As I stated in the OP, I expect to release the first version by the end of the year, so far I think I can keep that promise (also it depends of the feedback of the volunteers

)
As always, many thanks to the whole community for all the contributions and support.
Best regards!.
