Fear not, hermit gamers (like me!) and achievement fiends, for despite the addition of multiplayer to the Mass Effect, we’ve learned that none of the achievements will require gamers to hop into the competitive online environment, which requires Xbox 360 gamers to pay for a subscription to XBOX Live (multiplayer will be free on PC and PS3).
Details from Shacknews:
Even the game’s achievements reflect the optional nature of the online component. If you refuse to play co-op (or you simply don’t have an Xbox Live Gold account), you’ll still be able to collect every achievement.
For example, “Tour of Duty” has you playing all the multiplayer maps, or playing every “N7 mission” in single player. “Explorer” has you playing three multiplayer matches, or finishing five N7 missions. “Peak Condition” will unlock when you reach level 20 in multiplayer, or level 60 in single-player. Finally, “Unwavering” can be unlocked when finishing all the multiplayer maps on Gold, or all single-player missions on Insanity.
Its a nice approach from Bioware and should allay the concerns of fans unhappy with the addition of multiplayer to long-time single-player-only RPG series.
Mass Effect 3 will be released for PC, PS3, and Xbox 360 on March 6th. A demo will hit all three platforms sometime before that.
