Good evening gentlemen!
This week we have completed all the planned work on the patch and are planning to start its assembly and testing in the coming days. Therefore, we do find it difficult to give an exact release date. List of changes will also be published later.
We are however releasing some more screenshots from the upcoming sequel. This is the Soviet La-5 fighter that appeared in the skies over the Eastern Front in the latter half of 1942.
As always, we’d like to mention that everything you see is Work In Progress.
