I played it for 6 hours straight only got up once for coffee. It said BETA in the corner so this must be what we will be getting on 19th. Oh and the map was called Arica Harbour.

The perk system is immense and you unlock more as you go. From what I've seen there are no stupid perks like in CoD4, they all have a purpose to fit your playing style. All perks and unlocks are mostly tailored for your class though.
Each class has 6 tweaks. Primary weapon, secondary weapon, additional weapon, soldier perk1, soldier perk 2, vehicle perk. Then there is also class gadget that is not changeable.
Primary weapon is mainly class specific, Sniper rifle for Recons, LMG for Medic, SMGs for Engineer, assault rifles for Assault. Shotgun goes to more than one class though.
Secondary weapon, mainly pistols, as well as tracer gun for Engineer.
Additional weapon included C4 and mortar strike (air strike?) for snipers, C4 and grenade launchers for Assault, mines and RPGs for Engineer, and for Medic? I didn't check that one properly, Symonator did though. I guess defib, I was revived few times and it felt fantastic!
Perk 1 usually the weapon perk, like red dot scope or more ammo carrying or more hand grenades, better accuracy. Perk 2 is soldier perk, more health, become lighter and faster etc.
Vehicle perks I've seen were better armour, sensor radar, some other undefined perk that didn't have a name yet. The extra armour really worked though on my heavy. It could withstand many rockets providing you jump out and keep repairing it. But UAV can destroy a heavy tank with 1 hit. I think you call AC-130 for a missile strike(don't panic it is nicely balanced with long reloads) .
Non selectable gadget is also class specific. Drill for the Engineer, medpack for medic, ammo for assault, I suppose sensor for Recon, because it wasn't selectable on the screen but it was shown as unlocked. Didn't play Recon sorry.

The weapons in this game are SUPERBLY balanced. If anything, the weapons are the game. They feel good, shoot good, sound good, kill good. You can pick any weapon and own with it, I mean it, any. Demize99 has truly succeeded in his magic. There is recoil, you need to shoot in burst for increased accuracy. Mags are only 30 bullets now and if you spray and pray you will run out of ammo before you even manage to hit the barn from inside. Trust me the firefights are short lived and intense you either kill or get killed there are no long shootouts like in BFBC.

Everything feels like it has more weight to it in comparison to BFBC. There is a perk that makes your soldier lighter and faster, then it feels exactly like in BFBC. But the extra weight is not too bad, though I'd personally would want it exactly like in BFBC.

There is a UAV station at each attackers base. It looks like a tick sign on a minimap. BTW minimap was absolutely fantastic, much much much better than the one on Atacama Desert.
So this station has a joystick and a B/W monitor. You fly a mini chopper almost like a chopper but it is much easier as it hovers very well on its own as it is surveillance craft. You see everything like an eye in the sky and can update your team on enemy positions. But the best thing is if you press fire trigger you call a AC-130 and if you get a confirmation you have to keep the crossair on a target, few seconds later it's hit by a missile.
