I'm interested to see if it's just 2 player co-op, or if they are going to include it as 3 player (based on party size). Sadly i fear it might not be the single-player campaign, but rather special co-op missions. But lets wait and see at wednesday!
I got one thing to say: F*CKING YEAH! This is great news.We can officially confirm that there will be a multiplayer feature in Mass Effect 3. However, please reserve your appraisal until we are able to give more information. Our Executive Producer Casey Hudson says it best: "Yes, co-op MP missions for ME3: they're real, and they're spectacular. Rest assured it's nothing of what you've feared. More soon..."
Tune in for a special BioWareTV episode at 10AM on Wednesday October 12th to have all your questions answered!
