Well, this ain't out yet, either. Probably won't be out this year.
Played way too late yesterday night. Some further impressions: currently, the biggest issue is matchmaking, as getting even matches is very rare.
Basically, you get a few weapon classes - SMGs, "sniper" rifles (currently, only the top rifle in the class is actually a sniper weapon, the rest are just rifles with ironsights), shotguns (not all have buckshot), pistols and assault rifles (currently only represented by AK, a top gun).
You unlock more weapons and equipment (better armor) by gaining reputation, that you mostly get by completing missions (such as, get X kills in a match, get X kills in a row, achieve X% accuracy and win, bring X containers to your base, etc) for one of four factions. You generally have to be dressed in that factions clothing/armour to do the missions.
Rifles can generally kill in a single torso/head hit, or so it seems, but quickscoping isn't really an option, since rifles sway a lot, if you try and aim them after moving. You can steady your aim quite quickly by holding your breath, but generally you want to be standing still for a bit, before you try and kill someone with it.
So, yeah, currently the game is just an arena team-based shooter with some gear progression, but hopefully it will be a lot more than that, as development progresses.
