Thanks for the reply. I haven't finished the campaign yet so I was worried that I couldn't unlock stuff. So far I am enjoying it and hopefully you guys make the rest of the Soviet campaign till the fall of Germany and the invasion of Japanese controlled China

Version 8.1.0 64 bit Steam

I can't scroll the specialization screen put I can see there is stuff past 1943 like proximity fuse if I hover my mouse at the bottom just above close and acquire buttons.
