Аддон естественно.

The lines of battle are drawn in Combat Flight Simulator 3 and the most
famous aerial conflict in history is starting again!

The summer of 1940 marked Britain.s darkest hour. France had fallen. Alone
and apparently defenceless, we awaited the onslaught of the Luftwaffe
blitzkrieg that would spell the end to the free world.s resistance.
However, Hitler and his generals hadn.t reckoned with the skill and
courage of the RAF and for a few desperate weeks Fighter Command held back
the German air armada. The victory they earned was truly our finest hour.
Now it.s time to scramble once again and get airborne in CFS3 . Tally Ho!

Includes 40 authentic missions (20 RAF and 20 Luftwaffe) that re-create
events on noteworthy days throughout the battle, even down to the correct
weather and time. There are scenery improvements to the locations used in
the missions and a full suite of special effects is included, featuring
searchlights, audible air raid sirens which trigger when you approach a
target, bomb flares, smoke effects, realistic tracer fire, AI aircraft
involvement and more!
