Another BIG update coming to BoS at the end of this month which will see the release of the Kuban map with the water technology from RoF added to the game along with new FM calculations for all planes, new shadow technology, torpedoes, enhanced graphic options and the usual host of minor upgrades, bug fixes, etc.
Kuban release has now become an important step on the way to Battle of Midway - the next BoX theatre. Kuban also has - thank heavens - mountains and sea; a pleasant change from the endless steppe of Stalingrad and the equally endless regions of forest and marsh around Moscow.
Just a reminder if you has BoS but have not fired it up in a while; for several months now you have been able to access all of the maps in multiplayer even if you only have one of the base games. For example - if you only own BoS you are able to fly on the Moscow map in multiplayer.
Also, if you haven't updated your game in a while I would think it worth doing now - before the release of what will be a major, game changing patch.
Oh yeah; could not resist posting a quick Spitfire circuit in my Vb with Merlin 45M engine
