My intel shows me that there will be forthcoming a mod of Greece for CC3.
THis is one done also by andima and jr_andima, they made this mod for themselves in the past. It never went public, but now they are willing to shre this with the CC community as well

The time period set for this mod is end 1940 beginning 1941. The battles are situated on the border between Greece and Albania. The opposing forces are Italy and Greece.

There is no dedicated website for this mod
