Short answer?
Yes you can.
*END OF COMMENT*
No it does not. Multiplayer and campaign is a two totally different things which do not intercept with each other in any way.
Yes, there are U.S. Marines in the campaign and as a team in multiplayer.
You need a Jtag for Multiplayer, and a USB for campaign.
No, but there are individual co-op missions.
Ill give it 10 stars
you cant play the normal campaign online but you can play spec ops with two people online
This confused me for a second, but I got the answer. The resurgence is only a map pack for the online multiplayer, not campaign.
Let's say I have 10th Prestige in Multiplayer. If I want to start a completely new Campaign by going to the Campaign mode (inbetween Spec Ops and Multiplayer), and push the button 'New Game', would that erase my tenth prestige data and/or any other stats such as kills?
No, but only on spec ops its like campaign except its harder and more of a hardcore mission.
I'm pretty sure you can't. yea i tryed too you have to finish the campaign 10 times in a row with out dieing!
Yes it does to connect to servers but online multiplayer only so campaign is ok
That is the end of the campaign and you can then play spec. ops or multiplayer
