i don't fuqing know :( its frustrating
You don't do missions to unlock weapons you unlock weapons by leveling up.
You cant.
to unlock all the weapons you need a gameshark or a action replay, but you can unlock some too by playing the main game in normal and profesional mode.
I don't think there is cheats. All I know is that you have to unlock levels to get new weapons.
you unlock all weapons
you have to rank up to earn game modes, weapons, perks, and equipment
To unlock all the Call of Duty Black Ops weapons you must do numerous things. First, you have to rank up in order to purchase the weapons. Next, you must purchase the weapon with your COD points you gained in-game. There are some classified weapons that are available in the menus. To unlock that specific weapon for purchase, you must purchase all the weapons in that category in order to purchase that weapon. Example: There are 4 snipers and one is classified. Purchase all 3 snipers and the last one will be un-classified.
Nothing "happens." You just unlock all small weapons and can access them in Villa Auditore to use them as you please.
if you beat the game in comander you get all the weapons other than that there is no cheat the only cheats are infinate ammo, tnt, and gps coardinates
go 2 arcade pre hacks it gives all weapons but u have 2 do last lvl do get last 2
You HAVE to LEVEL up and BUY them with COD points.
You haw to look on computer!
