Tests for ToW3 WW2 Kursk are over now, only two of the testers have reported bugs, minor ones that have been solved. The only issue i couldn't solved yet is that infantry can't come in reinforcements in Multiplayer games, but it sems to be a ToW3 issue, because i have the same problem with stock missions with ToW3 WW2 Mod disabled...
Before releasing the mod, I'd like to add some single and multiplayer missions (and later after the release campaigns and "strategical" campaigns), Arzok is helping me and will update the ones he created for ToW2 !
Now again, we need more testers, join the team!
