Mass Effect 3: Galaxy at War

Mass Effect 3: Galaxy at War is an optional gameplay system in Mass Effect 3 that will allow the player to manage Commander Shepard's resources in the galactic war against the Reapers. Galaxy at War directly affects the state of the war effort in the single-player campaign, and can determine how the final confrontation of Mass Effect 3 plays out. Access to Galaxy at War will require an Online Pass which will be included with new copies of Mass Effect 3.

Overview
Mass Effect 3: Galaxy at War provides a strategic outline of the state of the galaxy in the midst of the war against the Reapers. A color-coded map displays the player's progress in the conflict. The goal of Galaxy at War is to prepare the galaxy for a counterattack to defeat the Reapers; the level of preparedness will determine the outcome of that battle. Using Galaxy at War is optional, however, and the same outcomes can be achieved by playing only the single-player campaign.

Galactic Readiness
Galactic Readiness measures Commander Shepard's influence and ability to utilize the galaxy's resources. The higher the Galactic Readiness level is, the more prepared Shepard's forces will be for the final confrontation against the Reapers.

War Assets
War Assets are the resources of the galactic war effort. Players can purchase different War Assets, including armies, fleets, and radar stations, and deploy them in the galaxy to increase the Galactic Readiness rating.

Interfaces
There will be multiple ways to interact with Galaxy at War that will affect the Galactic Readiness rating. Aside from cooperative multiplayer, additional interfaces on iOS and Facebook are planned, each with their own "hooks".

Cooperative Multiplayer
Mass Effect 3's cooperative multiplayer mode ties directly into Galaxy at War. Success in co-op rewards players with War Assets.

Mass Effect: Infiltrator
Mass Effect: Infiltrator is a third-person shooter for iOS devices. Playing Infiltrator can earn the player War Assets for the Galactic Readiness rating as well as unlock weapons for use in Mass Effect 3's single-player.

Mass Effect: Datapad
Mass Effect: Datapad is an app for iOS devices. It will allows players to monitor the Galaxy at War system and receive messages from Mass Effect 3 characters.
