Does this beta have a single-player component in it? The whole damn thing's about 1.7 gigs, so I'd like to figure out if it's worth my while to spend a day figuring out how to download it.
No, sadly it does not. But fighting online is fun enough for now. There's two maps available, all four command classes (Infantry, Armor, Support, Air), and a decent selection of units.
I haven't found what class I'm good at yet, but armor is probably my worst. Support is fun, because you can sit several arty units in the back of the line and pummel any likely enemy positions, but you have to watch out for counter-battery fire and any other enemy units closing the distance. Infantry is a tough class, because if your infantry is out in the open too long, they're gonna get killed by something. Infantry works best in defending chokepoints and holding ground in urban zones (in cover of course).
