For those keeping score: It did, and then it didn't, and then it might have and then it would. Now comes this pamphlet from South African retailer BT Games, which advertises a Collectors Edition of Mass Effect 3 that includes an "Online Multiplayer Pass." The flier was posted in the BioWare forum, the members of which then calmly discussed its content while still being respectful of the opinions of others. No, no, just kidding, they're on the internet, so they're still fighting about it.
Could "Online Multiplayer Pass" be a mislabeling of a Cerberus Network-esque online program? Possibly. But we've had multiplayer half-confirmed by rumors three times in a row now, and you know what that means, right? Totally confirmed.
