I am a new player and I have a question .
Does this game have something like career - witj ranks, medals, total score ,etc. or only campain
like a set of missions ?
It does but it's pretty basic so far. This is one of the areas that the developers intend to improve over time with the release of future patches. You can access the current campaign through the single player menu.
There may also be some user made campaigns available for download, check the 1C forums @ http://forum.1cpublishing.eu/forumdisplay.php?f=189 and Mission4Today @ http://www.mission4today.com/ to see what's on offer.
It does something in campain ? Where to look for results.
Each flight looks like separate.
