played it since beta, impressed me enough to get alpha squad and have been hooked since released. Yes, it is f2p, however, all weapons/upgrades are obtainable by in game currency... much like the other successful f2p's you only NEED to spend irl money on aesthetics or to speed up progress.
I for one don't think i'd like it if i wasn't always in a group of people i know like i am now and have heard others stories about how much it sucks trying to solo in this game.. It's a base defense/capture game with maps 200x the size of caspian border... get a team and play tactically sound and this game is irresistible.
The problem i had was the engine which is sometimes inconsistant. The graphics are nowhere near that of battlefield. I'm not sure with the maps being as big as they are, that they need to be detailed anymore than they're now.
