Advanced Warfare campaign theory

This is a theory on how multiplayer can correlate with the campaign. I don't want to hear bullshit like people saying "teh brij didn brayk on defender".

Evidence

 * More weapons in multiplayer than campaign, tech developments
 * Buttload of new gear for soldiers
 * Exo Launchers instead of typical pineapple grenades
 * A lot more obvious stuff

Alternate reality?
I've also noticed that in this "alternate reality", Gideon is still in Atlas and Irons is alive. Don't forget that the GG Bridge wasn't destroyed.
