Would make sense, I mean if you played any Mass Effect game, you wonder why there is no multiplayer..

Also maybe this means DLC Mass Effect 2 Multiplayer..

The next Mass Effect might not be a solely single-player experience. A new job posting on LinkedIn suggests that the series is taking a turn toward multiplayer.

Maybe "suggests" is too weak a verb - the BioWare Montreal opening (picture below) is for a "Multiplayer Programmer (Mass Effect Franchise)." Not much room for interpretation, there. The ideal candidate will have to come up with "solutions to deal with network latency, de-synchronization of data between networked machines/players, packet compression, cheating, and interrupted connections." They'll also have to "work with databases that allow for chat rooms, client/server games, player matching, player stats, etc."

One other tidbit, from the position summary: "[Multiplayer Programmers] work with both the front and back ends to take existing single player user experiences and make them multiplayer safe." I guess you could argue that means co-op. However, in a way all online play is just a translation of the single-player experience; both have the same basic mechanics, after all.

Back in February, EA chief operating officer John Schappert said something "far-reaching" would be coming for Mass Effect. Maybe this is what they meant?

co op might be nice.

ya think........

Yeah I think co-op would be alot better than versus multiplayer :)

i agree! co op > competitive multiplayer

Bioware games are MADE for multiplayer, it can easily be implemented.

that would be great next step bring it to ps3 pleaseeee!

No.

no wonder sales werent that great on the 360

Hmm...one would be observing from the ship or something of the sort and giving the other player player (the team commander) orders and updates based on the situation? I don't know, lol. It would be nice though.
