I have this game on Steam and I hope to finish this someday. I so want to enjoy this game as it fills a niche market in World War 2 games covering little known World War 2 battles. This game covers infantry, tank, and aircraft battles during the invasion of Poland. It plays like a classic Call of Duty game which we need more games like these. It is set in Poland for heaven's sake which should be right up GOG's alley.
However, my experience with this game is rough. Controls are sluggish on game pad as well as mouse and keyboard which makes it hard for me to play. The English voice acting is pretty bad. Enemy grenades are pretty unforgiving, reminds me of CoD World at War Veteran, even on medium difficulty. They were thinking about porting this to consoles but I think the mixed reviews probably led to the end of that. So not necessarily a great game, but still worthy of being preserved.
