Rallying civilizations divided by old conflicts is central to Commander Shepard’s mission in Mass Effect 3. The Reapers have overrun Earth, and Shepard must assemble a united military force while working to complete the Crucible, a Prothean superweapon that may stop them. Alliance-building decisions can determine which characters survive.
Players recruit squad members from different species and classes for combat built around squad tactics, combinable biotic and tech powers, blind fire and enhanced melee attacks. A separate cooperative mode supports up to four players fighting waves of enemies to liberate conflict zones. Progress in that mode contributes to war preparedness in the single-player campaign.
