ok, so some stuff i forgot to mention..
The game is kinda RPG style shooter, you ahve a large number of stats, and "choose" them based on mystic genes that have bonuses and penalties to certian stats, you choose 3 which lets you kit out fairly well either making a balanced jack of all trades, or straight magi, hacker, sniper, or warrior. Your class is defined by your highest stats, which doesnt do much except change the look of your armor and possibly a few other small things i havent figured out.
The weapons are pretty limited with about 3 melee weapons, your default katana, a secondary wakazashi for it, a giant broadsword called the damacles (sort of AOE swing attack that explodes enemies on contact) And a giant hammer/ax i havent gotten yet.
Pistols you have 4, a pair of dual pistols, a single pistol, a revolver, and heavy revolver, dual pistols let you dual wield of course, but if you take a melee weapon you can use sword and gun at same time (except the hammer/ax thing) letting you blast away till they get close, and negating some worry about the lack of auto-reload. Revolvers are simply more accurate and higher damage, but horrible reload time to make up for it.
Next up is SMGs, 2, a weird sort of pistol that has 2 settings, Full auto, and MOAR DAKKA!!! 100 shots its good for just sort of unloading at close range, especially with its MD setting where it blows through a clip of 100 in almost a second, but both modes have rather crap accuracy. Second SMG is a heavier one with a silencer (which i think is more of an astetic thing as moment you shoot anybody EVERYBODY knows..), higher damage, better zoom, switches between semi-auto and full auto with better accuracy
Assault rifles are next with 3, a full auto ak clone that works well at crowd control with its full auto shot, decent accuracy, a second AK clone which is semi auto, but has a better accuracy and is single fire. Third one i havent gotten yet.
Next is snipers, with a silenced semi-auto rifle with decent damage and zoom for quick kill head shots and a good clip, second is pretty much a .50 cal rifle. Hit the enemy anywhere and they are going down in a red haze. Third one i havent gotten again.
Next heavy weapons starting with a giant vulcan machine gun, huge clip, crap accuracy. An assault cannon that does AOE range damage (least from understand, havent gotten it) and a double barrel shotgun that looks like a troll on steroids would have trouble handling that fires grenades.
Shotguns follow up with three, a double barrel sawn off, a pump acction assult, and a machine gun shot gun, never really used so dont know whole lot bout them.
You can get any weapon at any time, provided you have the cash and stats to buy them, which is weird as you can kill enemies and pick up the exact same gun from them.. But you get no ammo.
Ammo isnt really a problem as you can visit an armory and refill with as much as you want, or find it dropped from dead enemies who almost always drop ammo for a weapon you are carrying, even if its a gun they arent using. So your never really hurting. But they only drop ammo for the guns you Own, not the ones you find, if you pick up an enemies pistol that you havent unlocked you get 2-3 shots before its useless as for some reason you cant take the unused shots from a dead enemies gun of the same type.
inventory is done in a grid based design, 2 slots on each shoulder, 2 on each fore arm, 3 on each hip, 6 (2x3) on each foot, and about 18 (3x6) on your back. This lets you either take one heavy, a rifle (sniper, assult, shotgun) and a melee weapon (broad/katanas), and room for 2 smaller weapons, like pistol and SMG (or the sawn off shotgun) and load up with all the ammo you want. So you have to pick your gear carefully, though you can go back to your armory at any time and change your loadout if you need. The down side to all this is it lowers your speed, more, heavier weapons slows down your running speed and eats up how fast you use energy while running, this is also modified by your armor, and your strength, higher STR means you can use heavier stuff without slowing down, higher endurance means your energy goes down faster.
The lack of weapons is kinda disappointing, but at the same time its kinda nice as you can get away with favoring a weapon (or group) without having to worry to much. Pack along your sniper rifle for long ranged armor targets and a pair of pistols and SMG when things get hairy. In the end its free enough to let you make your choice and run with it, but strict enough to make you keep things a little loose so you can change up when you need to.
Will post more as i get further in the game.
