Yesterday I won as Axis. In short my strategy was to threaten UK with my first buy 2 trannies and a CV. I eventually used them to strengthen Scandinavia and scare off the RN.
I built an IC in Norway and together with the trannies I made sure Finland had a massive army. Only on turn 4 I DoWed Russia and captured the Baltic States, Karelia and Vyborg with large armies. Bes and EP I took with small forces. Russia managed to kill my Baltic army, but the other two, combined with an invasion force took Leningrad, even though his first defense dice rolled only hits! Literally every inf, armor and fighter hit the first round. Cost me my complete inf I brought.
It was never recaptured. Italy managed to do well in Africa and built an IC in Egypt. It took all of the Middle East and even invaded southern Russia.
The US was too late and even though they landed with a massive army in Normandy I could take it back (with only one tank left…), but that was enough. It took them too long to get another shipment accross the sea, because Moscow and Stalingrad would have been captured by then. The allies gave up.
