or stupid:

Gamers who haven't yet unlocked all of Black Ops' zombie-based multiplayer modes are to get free access to the hidden content this weekend, developer Treyarch has announced.

To mark the President's Day holiday weekend in the US, the Dead Ops Arcade and Five modes will be open to all players until Monday evening.

For the uninitiated, Dead Ops Arcade sees you and up to three other players pursuing the Cosmic Silverback through a number of zombie-filled arenas filled.

In Five, you'll assume the identity of one of four Cold War icons - John F. Kennedy, Robert McNamara, Fidel Castrol and Richard Nixon as they attempt to rid the Pentagon of wave after wave of ravenous brain-munchers.

Wow treyarch, not only can you unlock Five by finishing the small campaign but you can enter an code. 

and it doesn't matter, Five was poorly designed and is the worst zombie map treyarch has made hence on PS3 100,000 play kino map while 10,000 five. More people play dead ops then five and probably zork as well is played more 

Ive yet to beat the campaign (i have played 5)

Also never underestimate how daft people can be, my bro rest his soul, never figured out until i showed him that you could change the direction on stealth bombers and precision airstrikes in mw2.

So? I think people who buy Call of Duty are all or stupid, too.

I just bought COD:BO and is my first COD ever so I didn't know about this.

call of duty gamers are stupid.
