Online campaigns

I like to beat the game before i jump into online play. I think that people should be forced to actually beat the game before the Online mode is avaliable. PS3 —- StoStatus add me up

i am playing cod5 and want to play **** zombies online. I never beat the campaign on that account so do i have to go and beat the campaign before i can play **** zombies online.

My XBL gamertag is xXThE sToNezXx im playing on normal
The game is Modern warfare 2 haha sorry forgot to mention that

i played the demo but i got the game not too long ago playing campaign but is online free?

Me and my friends love to play Halo 3 and Gears of War online in Co-Op Campaign mode… But we are looking for more suggestions on what games to get with good co op modes.

I can still play campaign mode but not multiplayer online. I have an xbox live gold membership and all my other games work on it.

I just got ODST today and I thought there was an online co-op feature to play the campaign. This game is really hard and would be much better with 2+ players. I see the “Firefight” mode but thats only like waves of Covenant like Horde. How can other people join my campaign game and how can I join theirs?…is this even possible over public Xbox live?
Firefight is pretty cool but I’m not impressed with the rest of the game…too much running around the city with not enough to kill or the enemies are too hard to take on by yourself. I don’t have any friends with ODST yet. It would be much better with matchmaking but I’m sure I’m not the first to say that

Will I be able to play online campaign over xbox live with a friend?

My brother works fine, is it my xbox because its an older Model?? I have xbox live gold i cant think why?? Please help!!
my online works as i played gta 4 with my cosuin yesterday,
its working now

I want to beat it on legendary so i need people to play with. But idk if theres a way to search for players online or if you have to invite friends.
