Good start. Seems like a pay-to-progress-faster type of game. I do not like the idea of buying campaign levels. Needs some polishing but it is beta so maybe it will look different in one year. Plane controls - I hate them.
Progression seems like will be painful. You have to level all your many squads in 2 factions in 4 campaigns separately. So it is new weapons for them and new skill points. Let's say 10x2x4=80things to level up - that is a lot of battles to get enough exp.
Well, if you like World of Tanks/War Thunder and so on a year-long grind - you will like this as well.
