Epic. All the scale, tactics and teamwork of Arma, but with the pick up and play accessibility of something like halo and none of the 20min run to get shot in the face and start over nonsense. The spawning and vehicle systems are brilliant at getting you in a fight quickly. The social/comms side of it needs taking to Dice HQ and shoving down their throats. Want to invite/chat/squad/whatever with someone do you have to tab out and muck around in firefox on a clunky facebook clone? No you look at them and press Q.
The actual gameplay is fantastic too, I spent most of yesterday with a 10man infantry squad of randoms and despite being on a server where the main elements of each faction were in the hundreds and pulling full multi axis assaults with masses of air and armour, we were still able to tear it up and be useful in the larger battle; raiding, flanking and in one particularly gorgeous battle acting as an FSG from a ridge as a 2 massive assaults went into a base resulting in a 3 way fire fight so ridiculous John Woo would be jealous. 150ish tanks, 100+ aircraft and hundreds of infantry from 3 Factions fighting over base about half the size of a BF3 map and all of it in the valley below us. New king of F2P and contender for GOTY imo.
