Battle for Europe

[vpmedia]

its a must if you want to fly allied dgen campaigns over western and central europe (Normandy,Berlin,Ardennes,Hungary)

for the complete dgen campaign experience (if you want to play all campaigns available) you'll need IL-2 1946 4.09 + BOE + OSTFRONT + EnjoyR Dgen patch/update from mission4today.com

although there's a free patch called EnjoyR Dgen patch for no addons includes a few campaigns which are similar to the BOE ones

there are many other addons, but those include scripted missions therefore didnt required the involvement of Starshoy who did the official dgen programming for Maddox games so I would call these dgen addons (Boe + ostfront) official
