Is it true that does call of duty black ops 1 have zombies based on the following text?

A zombie cooperation mode, titled ''Zombies'', is included in the game. Originally featured in World at War, it was revamped to be included in Black Ops. It is a four-player online and two-player split screen co-op mode (which can also be unlocked online). Based on the original game, in the map ''Five'', players take the roles of John F. Kennedy, Richard Nixon, Robert McNamara, and Fidel Castro as they fight zombies at The Pentagon. Another map, called ''Kino der Toten'' (''Cinema of the Dead'' in German), features the characters from World at War -- Edward Richtofen the German, Tank Dempsey the American, Takeo Masaki the Japanese, and Nikolai Belinski the Russian. Limited editions of the game offer graphically-enhanced versions of the four zombies maps from World at War, featuring the newer weapons from the rest of the game. There is an unlockable top-down, two-stick arcade-shooter version of Zombies known as Dead Ops Arcade.
