We just released the 4.605 update. The changelist is not as long as usual, but one of the additions is very important for all who prefer single player – Advanced Quick Mission Generator. This mode is designed for cases when you want something more advanced than a simple Quick Mission and less advanced than a full Career and gives the player instant access to customizable combat missions on Moscow, Stalingrad, Kuban and Rhineland maps. Base airfield, aircraft, time, weather, mission target, etc. can be customized, yielding a quick way to create and play a unique scenario you want (none of them will be the same thanks to variability). We’re positive you’ll like it.
