Where do you buy weapons in cod black ops?

Answer 1

You must be on xbox live to do it. If you are on split screen or system link then you already have every thing unlocked. If you are not level 4 then get to that level. Then go to create a class, choose either primary or secondary weapon, go to the category you want. you need to unlock most guns though. Then it will prompt you select either buy or buy and equip, for if you want to use it straight away. You buy other things the same way. Find it then choose to buy or buy and equip. you have limited money though but to earn more you can just play matches.
