BioWare is set to unveil a "killer new feature" for Mass Effect 3 in the next issue of Xbox World, on sale October 25.
That's according to the next month page in its current mag, which is on news stands now sporting Aliens: Colonial Marines and Jonathan Blow exclusives (buy it online here).
Mass Effect 3 has of course been strongly tipped to be including some kind of online mode.
The first hint that the game would contain multiplayer slipped out in a BioWare job listing for a 'Multiplayer programmer (Mass Effect Franchise)'.
Since then industry 'sources' and other reports have supported claims that the game will come with a "Horde-style multiplayer mode," as well as established multiplayer types such as Deathmatch, Team Deathmatch and Capture the Flag.
But BioWare dismissed forum chatter on the subject when a rep said: "Mass Effect 3 is a single-player game."
