Yes there are permanent.
You unlock guns by reaching the level required to unlock that gun, but if you want to use it in your custom class, you have to buy it using COD points.
no at cod xp they confimed that there will not be cod points. But in the new mode survival you get cash for kills wich u use to buy guns and call in kill streaks.
It is based on guns
You go on create a class then buy the gun you want with cod points then click on buy and equip
You could buy guns,emblems,titles, gun camo,perks Well you need them to buy the stuff you want you cant unlock it like mw2 you have to buy them
All the guns are the same price. 2000 CoD points. Except for the pistols which are 1500 CoD points
You buy it for 2000 CoD points as an attachment It's only availbe for Sub-Machine guns.
there isnt a number code.
Gun wise will cost you about 60,000 cod points Then all camos are 200 cod points Gold camo costs 50,000 per gun and there is about 30 guns. Your looking atleast 2,000,000 cod points just for guns and camo So after perks, perk pros, special / lethal grenades you'll be hitting the 3,000,000 mark
These are automatic sentry guns.

all guns cost 2000 cod points which you can earn in 4-6 matches and there are 36 guns i think hope this helps
