Bioware has dropped a multiplayer video showcasing Mass Effect 3's cooperative gameplay as species join together to take out the Reaper (and whatever else the universe throws at them) threat.
While it looks a fairly standard take on the game's impressive combat system, what's worth noting is the brief glimpse of the galactic map; while it could be a simple interface for choosing which conflict to take part in, the emphasis the studio is putting on the 'Galaxy at War' aspect of the title makes you wonder if the success of individual online campaigns will gradually effect the ongoing conflict over time.
