Cooperative multiplayer is a game mode that is 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, as well as Cerberus, Geth and Collector forces. 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.
Playing the Mass Effect 3 multiplayer mode requires an Online Pass.
Missions in cooperative multiplayer consist of pitting the player and up to three other allies against eleven waves of enemies, including Cerberus, Reaper, geth, or Collector (requires Mass Effect 3: Retaliation) troops on various battlefields throughout the galaxy. Players must survive these waves by eliminating the enemy forces, and also accomplish objectives.
All objectives have a time limit, and the mission will end if time expires. There are five types of objectives, chosen randomly at waves three, six, and ten:
- Devices: Enable or disable four key devices in sequence.
- Assassination: Take out four targeted enemies in sequence. Time is extended after each kill.
- Hacking: Capture and hold a point in order to hack critical data before time runs out. Additional players within the hacking zone quicken the process.
- Retrieval (requires Mass Effect 3: Rebellion Pack): Retrieve two high priority packages and securely transport them to a designated extraction zone on each map. While carrying the package, players move slower than normal. Using sprint, combat rolls, and certain powers (i.e. Biotic Charge, Tactical Cloak, Shadow Strike, or Havoc Strike) causes the player to drop the carried package.
- Escort (requires Mass Effect 3: Earth): Activate and escort a drone to an extraction zone while it collects data. Additional players within the escort zone quicken the process. The drone itself is invulnerable and will occasionally replenish player shields and attack enemies with missiles or electrical shocks.
After completing the objective, remaining enemies still have to be eliminated to complete the wave. Each objective awards a base amount of credits (depending on difficulty) and a bonus depending on the amount of time left.
On the eleventh wave, all players must defend against the enemy for a set time period, then retreat to the designated extraction zone within the time limit. Though the mission is considered complete after clearing the tenth wave, bonus experience (relative to the amount of players extracted) and bonus credits (if the player survives extraction) are awarded after completing wave eleven.
Missions have four challenge difficulties, in order from easiest to hardest: Bronze, Silver, Gold, and Platinum. Platinum difficulty was added by the Mass Effect 3: Earth DLC pack. Higher difficulties feature stronger and more numerous enemies, as well as difficult enemy types in earlier waves and in larger numbers, but will also reward more credits to spend in the Store. Platinum also features enemies from factions other than the one chosen.
Mass Effect 3: Galaxy at War Edit

Playing cooperative multiplayer ties into the Mass Effect 3: Galaxy at War system. Participating in matches can quickly increase the player's Galaxy at War Readiness rating, and multiplayer characters who reach the maximum level can be "promoted" into valuable War Assets for 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 single-player, although the process could be considered significantly more difficult.
Each map, unless chosen at random, is associated with one theatre of war and will increase readiness mainly in that theatre.
Completing a multiplayer mission while having a readiness rating of 100% grants a 5% boost in experience earned, shortening the amount of time it would take to promote a multiplayer character to the Galaxy at War.
Each multiplayer user has several associated Rankings. These rankings serve as an indicator of players' overall level of experience with the game. Each can be viewed in multiple locations in the multiplayer system, but are prominently and publicly displayed in the lobby before a game. They are displayed on banners underneath the player's name.
The N7 Ranking is displayed on a red banner, and is calculated by adding together the total levels ever gained by each class, plus 10 for each time a class has been promoted. The Challenge Ranking is displayed on a gold banner, and is the total number of challenge points the user has accumulated. The previous are uniform across all classes. The third, blue banner is unique to each class and shows the number of times that class has been promoted.
Character Customization Edit
- Main article: Mass Effect 3 Multiplayer/Character Customization
Players can choose from six different classes and twelve different races to create a unique multiplayer character. Characters' weapons and equipment can be customized between matches, and additional weapons and equipment obtained by purchasing packs from the Store. Leveling up and promoting characters directly affects a player's N7 Rank.
- Main article: Mass Effect 3 Multiplayer/Store
The Store sells multiplayer item packs and distributes reward packs from weekend events. Contents of these packs include new weapons, multiplayer characters, experience points, weapons mods, and pieces of equipment, all of which are of varying quality. Credits to purchase packs from the Store are earned through gameplay; alternatively, packs can be purchased with Microsoft Points on Xbox 360, BioWare Points on PC, or currency on PlayStation 3. Packs can only be purchased via in-game credits on the Wii U version of the game.
Weekend Challenges and EventsEdit
Weekend Challenges were held every weekend, and feature objectives that individual squads or players can complete. Upon successful completion of the Weekend Challenge, players were rewarded with Commendation Packs containing unique weapons.
Weekend Events were held periodically during weekends and featured objectives that the entire community can participate in. Successful completion of Weekend Events rewarded players with item packs.
Weekend Challenges and Events concluded with Operation Lodestar on March 10, 2013.
Depending on how well individual players or the entire squad does, at certain milestones, they will earn medals. The awards are leveled by Bronze, Silver, and Gold with each having their own individual levels.
Individual Medals Edit
Individual Medals are awards earned by each member of the team. They are specific to each character and are not shared with other members of the squad. Each weapon class, in addition to tech and biotic kills, has its own medal for killing enemies with it. There are also medal for assisting other squadmates with kills, reviving downed squadmates, and getting headshots with any weapon.
Individual medals cannot be earned again in the same match. You can only get one of each individual medal per match. The Bronze level of a medal gives +500 xp, the Silver level gives +1000 xp, and the Gold level gives one of two bonuses: +1500 xp for weapon kills, and +2000 xp for anything else.
Not all characters can earn every type of medal, obviously. Weapon medals are limited by the weapon loadout (0-2 out of 5), tech and biotic medals by the characters abilities. Volus, Krogan Warlords and Geth Juggernauts also cannot gain over-cover grab medals (since they cannot perform the action).
It is possible for actions to contribute to more than one medal progress, such as performing a Headshot with a Sniper Rifle.
|Medal Title||Bronze Medal||Silver Medal||Gold Medal|
|Assault Rifle Kills||25||50||75|
|Heavy Pistol Kills||25||50||75|
|Sniper Rifle Kills||25||50||75|
|Submachine Gun Kills||25||50||75|
Squad Medals Edit
Medals are earned by the squad for killstreaks, the percentage of players that successfully extract, surviving multiple waves consecutively without a single squad member going down, completing an unknown map, the difficulty level of the completed match, and completing the map with unknown enemies.
Medals for survival and killstreaks are earned regardless of map completion. Level, Map and Enemy rewards are earned at the end of wave 10, extraction at the end of wave 11.
|Medal Title||Bronze Medal (Bonus XP)||Silver Medal (Bonus XP)||Gold Medal (Bonus XP)|
|Extraction||Lone Survivor (+2500)||Partial Extraction (+5000)||Full Extraction (+15000)|
|Killstreaks||1 Killstreak (+2500)||2 Killstreaks (+5000)||3 Killstreaks (+10000)|
|Level Completion||Bronze Difficulty (+2500)||Silver Difficulty (+5000)||Gold Difficulty (+10000)|
|Maps||Unknown Map (+2500)|
|Enemies||Unknown Enemy (+5000)|
|Survival||3 Waves (+2500)||5 Waves (+5000)||10 Waves (+15000)|

- Issues had been reported with already unlocked kits, characters, and items becoming locked again, typically after switching kits. This bug was remedied and now it is impossible to buy kits from the store while "ready".
- Another bug occasionally happened by using Biotic Charge immediately before getting knocked out. It would cause the player to glitch heavily during movement, float several feet above the ground, before getting stuck either right underneath the map or several hundred feet above the ground. This glitch was fixed by Patch 4. 
- It's reported that host migrations can cause bugs with locking too.
- Sometimes when grabbing enemies, the grab animation will not occur, and the enemy will appear beside you, invincible. Should this occur, it is advisable to avoid that enemy until they die on their own (usually falling through the map).
- A bug had been reported that the Ultralight Materials upgrade for SMGs did not actually reduce power cooldown times. This bug was incorrectly reported to be fixed in Patch 1.03, and was eventually fixed with the next patch.
- The cancelled first-person shooter game, Mass Effect Team Assault, served as the basis for Mass Effect 3's multiplayer.
