It is based on guns
Yes there are permanent.
there isnt a number code.
In my opinion black ops is better because I like the guns better
MW3 is after COD black ops.
3575
These are automatic sentry guns.
All the guns are the same price. 2000 CoD points. Except for the pistols which are 1500 CoD points
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.
all guns cost 2000 cod points which you can earn in 4-6 matches and there are 36 guns i think hope this helps
Cod black ops
