This is a very solid backbone of a shooter, with extremely finely crafted controls and great performance optimization. The content that rests on that backbone might be a bit questionable but even if you think it's garbage, it's garbage that you can play very efficiently. The options menus give you an exceptional amount of room for customization, even letting you pick individual mouse sensitivity to each separate type of zooming that happens in the game.
P.S Please don't believe any part of any story that this game tells about World War 1. It's pure fiction, and probably also afflicted by the developers' agendas. -And the last thing you should do is attempt any of the so-called tactics that were used. You do not try to take out anti-aircraft defenses using aircraft.
