News for July 4, 2017:

1) Regarding downloading the build - there are 3 options (RuTracker, Mail.Ru, Mega.Nz) http://el-mods.ru/load/4-1-0-12

2) Since access to Yandex, VKontakte, Odnoklassniki, Mail.ru, and other Russian websites has been blocked in Ukraine by presidential decree, Ukrainian residents are advised to install the free application "Вільній країні — Вільний.нет" to unblock them. https://vilny.net/

3) Please note that not all maps allow you to choose heroes from Campaigns. For example, on the map "Harsh Times," you cannot select Freya, Bertrand, or Nicholas. This is done intentionally – it was designed this way by the authors of these maps. However, there are maps where the authors have added many new Heroes with new parameters, for example:

1) scenario "Uninvited Guests" /topic/12098/
2) scenario "Pack Leader" /topic/10210/
3) campaign "Dark Mission" /topic/5015/
4) scenario: "Two Sisters" /topic/10794/
5) scenario "Unity of Elements" /topic/10586/

4) Work on updates has been temporarily suspended... but updates will be released when the author and creator of the mod - Denis Rakhmatullin - returns to developing the mod.

4) The UNIT_BALANCE mod is currently not compatible with EWA; try other mods, such as:
a) LBE mod - minimal changes towards balance for Heroes V
/topic/11956/
b) Balanced Units - Minimal unit balance mod /topic/12208/
c) other balance mods.
/topic/10183/

5) If you see this error when installing EWA - "Error launching application 0xc(000007b)," we recommend downloading a different version of the game (Steam or Buka), for example: a licensed Russian-language edition from Buka:
