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. Other missions include attempting to complete timed objectives like activating beacons while fighting off Cerberus troopers.

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.

Races
While the full list of choices has not been announced, at least six races are available for players to choose from when creating their character. These include: Each race possesses a unique ability, such as the krogan being able to charge enemies.
 * Asari
 * Drell
 * Human (Male or Female)
 * Krogan
 * Salarian
 * Turian

Classes
In addition to race, players can also choose one of six classes for their character. These are the same classes available for character customization in the single-player mode. Race determines which classes are available. For example, the asari can be Adepts or Vanguards because of their biotic strengths.


 * Adept
 * Engineer
 * Infiltrator
 * Sentinel
 * Soldier
 * Vanguard

Armament
Players can customize and unlock upgrades for their characters' armor, powers, and weapons.

Progression
During gameplay, players can increase the level of their characters. Cooperative multiplayer character leveling is capped at level 20.
