There is a two-week free trial. I used it
Action part reminds of Operation Flashpoint a LOT. Same feeling of well.. being cannon fodder.. But urban fighting at dawn in a bombed village with aircraft buzzing above is great.. And then you get a rifle round in the eye and start pushing up the daisies which are plentiful there.
There's also some kind of resource system which makes sieges possible. I remember one small town where all but trucks and rifle infantry spawns were expended so every single tank and AT gun was such a great value that guys dragged the gun into a bombed building every time a plane was approaching. Actually it was after that episode that I realised that limitations of weapons available to a certain rank are perfectly justified. Newbies would all hop into Tigers and Shermans and grab sniper rifles and drive Destroyers into the sea - and be dead with all the valuable equipment in less than a minute. Wasteful.
And the huge seamless map is great... I took off at a German airfield, flew without interruptions all the way to front line at dawn, scared the oil out of a sleepy Spitfire and hit him hard, though not downed. Then got shot by the flak pretty hard, legs wounded - decided to return to friendly lines, lowered gear too early, lost it, jammed flaps, crash landed onto a field (don't land in the forest EVER). Despawned and returned to base..
