Well, I'm in Planetside 2 guys.
It's terribly unoptimized, so update those graphics drivers, and it has a tendancy to start rubberbanding a bit (not much recently), but it's quite fun.
The game world is divided up into a series of hexagons.
Bases are scattered across the landscape, providing spawning for players, vehicles, or aircraft depending on the facilities available.
You capture a base by capturing and holding all of the subsidiary points inside of the base/outpost complex, anywhere from 1 - 6.
After the base is capped, you can now use it to change class, spawn vehicles, or spawn air vehicles.
[*]Controlled bases provide the entire faction with rescources.
[*]There are 4 rescources available, each one used for a different classification of armor, weapon, or ammo needed to be spawned or resupplied.
[*]Controlled rescources provide the bounty every 5 minutes or so, faction wide, so it's possible to idle for the rarest rescource, which is used to buy weapons, vehicle upgrades/sidegrades, and other benefits.
[*]The rarest rescource also takes forever to earn.
[*]Currently, the game feels like a neverending match of BF3 spread out across a massive landscape, between three factions.
The light gunship, analagous to fighter/bombers, is cheap and plentiful with multiple roles to fufill. They are typically seen with machineguns stock, and rocket pods or AA missiles can also be equipped after one hell of a grind. These vehicles serve as a key part of the aircav, defending the lumbering galaxy dropships, raiding, dogfighting, and going on much-needed ground attack runs. It can hover.
The Liberator is a 3 man mid-size gunship with pilot controlled MG guns, a secondary MG turret stock for a gunner, and a massive smartbomb launcher on it's rear. No matter what loadout you give it later in the game, it will devestate ground targets. The smartbomb launcher has 5 (YES 5) rockets per reload as TR, and it's perfectly accurate. It also accounts for the motion of the plane. Fun as hell.
The Galaxy is a massive 12 person dropship, with 3 HMG turrets for air/ground point defence and the ability to deploy as a mobile spawner when landed. Troops can hot drop from it at any time, taking much reduced fall damage and allowing for quick insertions into enemy territory. The dropship is heavily armored, but it's speed and size makes it a juicy target for enemy fighters.
[*]Ground vehicles so far are quite diverse between the factions, all of them having different weaponry and propulsion systems. This also applies to air vehicles, but the TR and the NC are much more similiar compard to the exotic weaponry and levitation that the VS use.
Flash ATVs, one man vehicles that can mount a defensive weapon but are lightly armored and provide no protection
Prowler Light Tanks, armed with light autocannons stock or a light gun depending on the Faction, and generally fast. Can mount AA missiles, making it the most deadly defense in the game.
MBTs are pretty average overall, heavily armored and slow, but the TR get's a siege mode ability that allows for higher accuracy and a greater ROF. VS have hovercraft for all vehicles.
[*]Infantry Classes
Light Assault, a light infantry man equipped with a (soon to be) upgradable jetpack, a pistol, and a Carbine. Pretty average, but great for infiltration of bases.
Medic, a revival/healing expert who carries a shield also, and uses a fully fledged assault rifle stock, meaning he has more firepower.
The Engineer, who can heal MAX suits and vehicles along with base stuff, and can deploy a useable turret and bubble shield along with ammo.
The Heavy Assault, who comes equipped with a shield ability (giving him more health for a short time), and packs a LMG, Pistol, and Rocket Launcher.
The MAX, a heavy combat suit with a gun per arm. Slow and big, but powerful as hell. Treated as a normal infantry class, oddly enough. Can have Grenade Launchers, Flamethrowers, MG's, Shotguns, AT guns, etc.
[*]Ground vehicles seem much less common compared to air vehicles, but considering the map size, that would make sense.
[*]Any unlocks that arent Cert based (cert's are earned like skill points and work the same way, and can be used to upgrade MANY things along with unlocking weapon attachements) are unlocked via the rarest Rescource or station cash (both work), and take a LONG time to get. 2 days of straight playing according to some. Sadly, this is the only way to get new guns, AA missiles, Rocket pods, etc.
[*]Spontaneous group actions may occur, and try to join them when possible. Just follow the vehicle/air convoy or check the map for the heaviest concentration of firepower. Loads of fun.
[*]Try to find a good, out of game squad, and use TS3/Mumble. Much better than random people in game.
Factions all are pretty unique, TR focuses on ROF and mag size among other things, VS on unconventional tactics and mobility, and the NC are pretty down to earth, using conventional heavy armor and equipment but with a bit higher damage and armor.
All in all, as long as they don't horribly screw the game over by making it even more dependant on grinding or P2notgrind, it's going to be a great game.
