In Call of Duty 4 there are no multiplayer options for story mode, although Call of Duty: World at War does have this feature.
there are 4 ps2 Call of Duty's. These are Call of Duty 1, 2, 3 and World at War
no there is not a CoD 3 on ds. but there is call of duty 4 MW, CoD modern warfare 2, call o duty WAW, and a new call of duty on ds: call of duty black ops.
the only cheats that you can unlock in call of duty 4 are the ones from collecting Intel in the single player campaign. Other than that there are no other cheats for call of duty 4.
No but Call of duty World at war has 2 player co-op on the campaign but black ops has 4 player zombies (4, 3, 2, 1 online and 2 or 1 offline)
