Just ran across this, still in open beta. It's not horrible and has provided 2 weekends of amusement so far. Four classes, two skill trees per, inventory. 3 maps
Cons: No voice, and spending real $$$ buys you advantages in weapon power. Only 2 character slots and no way to delete toons you don't like ($$$ buys you extra slots, of course).
Pros: the freebie equipment loadout is decent. Vehicles! Decent amount of options. Less than a 5 minute download.
