Mass Effect 3 Multiplayer

Cooperative multiplayer is a game mode that will be featured in Mass Effect 3, and marks the debut of multiplayer in the Mass Effect series. In this mode, up to four players can join together online and customize characters to fight on the front lines of the galaxy-wide war against the Reapers. Progress in co-op earns the player rewards in Mass Effect 3: Galaxy at War that can be used to influence the outcome of Mass Effect 3's single-player mode.

Missions
Missions in cooperative multiplayer consist of pitting the player and up to three allies against eleven waves of enemies, including Cerberus troops, on various battlefields throughout the galaxy that can also be seen in the single-player. Players must survive these waves by eliminating the enemy forces, and also accomplish secondary objectives such as retrieving data packets from around the map or defending an ally while they perform a hack on a beacon. On the eleventh wave, all players must retreat to the initial landing site of a map and defend against the enemy for a set time period until an evacuation shuttle arrives. Succeeding will win the match.

Missions have three challenge difficulties: Bronze, Silver, and Gold. Bronze is the easiest difficulty, and Gold is the hardest. Playing on harder difficulties rewards more credits to spend in the Store.

Mass Effect 3: Galaxy at War
Playing cooperative multiplayer ties into the Mass Effect 3: Galaxy at War system. Success in co-op missions earns players War Assets, such as allies, fleets, and radar stations which can be deployed in Galaxy at War to aid Commander Shepard's fight against the Reapers in the single-player campaign. Co-op and the Galaxy at War system are entirely optional, however, and are not necessary to achieve the optimal endings in the single-player campaign.

Class and Race
When creating a multiplayer character, players can choose from six classes and seven races. Certain races are only available to choose with certain classes. For example, human characters are available for all classes, but the asari are restricted to Adepts and Vanguards because of their biotic strengths. Each race possesses a unique ability, such as the krogan being able to charge enemies.

Players can also create unique names for their multiplayer characters and customize armor coloration.

Powers
During gameplay, players can increase the level of their characters to unlock new powers. Cooperative multiplayer character leveling is capped at level 20.

In addition to the powers listed below, each class also has Fitness.
