There is no best weapon in Call of Duty, it's all about your personal preference, if you like a weapon use it. If you don't like it, don't use it:)
well for me its a mp7 but you can choose any weapon that you like
The AK-47 should be your first pick.
It was your weapon!
It is all about how good you are with the gun.
The only Call of Duty game to have a weapon camouflage labeled snow is Call of Duty: Modern Warfare 3. Other games had snow type camouflage but called it by a different name.
Level Up.
This is more of an opinion question, but the assault rifles seem vastly superior in Call of Duty: Black Ops. I recommend the AK-47 with extended mags.
The best gun on call of duty WAW would probably be the M1A1 Carbine. The PPSH and MP40 are decent weapons also.
Yes you can get it as a secondary weapon but you have to unlock the perk overkill.
The best at Call of Duty is who invented it.
all the weapon you can get in a mutiplayer mode.
the wunderwaffle is a wonder weapon on call of duty world at war zombies
