any I think
if you do hardline perk you can change care packages.
you cant but you can change your clan tag from the playercard option
No, you can't. You can only get the emblems when you prestige.
You cant exactly make a gun in black ops, but you can customize a gun in multiplayer create a class mode and play online (or offline) with the customized gun.
Yes, go to barracks and got to 'customize emblem' or something like that
online multiplayer, you can't really customize your player. But, if you look your player and change the first perk (hardline, scanvanger, etc.) you can tell that your player has changed to look like what the perk says.
Go to player card. Click edit player card. Then you customize your own. If you don't do this, it will just display your rank.
It's only on xbox LIVE but you go on customize than character the you start customizing!Hope it helped.
You have to hook your xbox 360 or ps3 up to the internet, and update the game then when you go on "multiplayer" you should beable to customize your match.
Around level 30, you will be given the option of changing your aim. After that, the color of the aim and finally the lens color. This only works on Red Dot and Reflex sights.
Yes you can I think if you go onto options on the relevant section you are on single player, multiplayer etc.) then at the bottom it should say reticule settings i think.
