EA has confirmed that every new copy of Mass Effect 3 will include an Online Pass, giving gamers access to the recently revealed multiplayer mode.
Mass Effect 3's Galaxy at War system will be activated once the pass code is redeemed, whereas second-hand buyers who aren't lucky enough to find an unused code will have to purchase one from their platform's respective digital store.
Galaxy of War will be used in the single-player campaign and in a number of games and applications released on iOS devices and Facebook.
"The theme of galactic war in Mass Effect 3 presents us with the perfect opportunity to introduce multiplayer into the Mass Effect series," said Casey Hudson, executive producer of the Mass Effect series. "Multiplayer not only features amazing combat and deep customisation options, but it will give players another way to help the war effort against the Reapers in the main event - the single player campaign."
BioWare has already detailed Mass Effect 3's four-player co-op multiplayer. The game hits stores for Xbox 360, PlayStation 3 and PC on March 9 2012.
It's no surprise to find that an online pass is required to access Mass Effect 3's multiplayer mode - it's now common practice not only for EA but across the games industry.
