    Galactic Readiness can also be increased using the iPhone, iPod and iPad app called "Mass Effect 3 Datapad".

    The app increases readiness at a slower rate than actually playing multiplayer, but providing you're willing to check into your i-gadget every hour or so, you can easily earn +10-15% readiness in every sector per day.

    You need an online pass for the app to transfer data to your Mass Effect 3 game (thanks to mDoolin14 for the confirmation).

    Edit 2: The app has been removed from the App Store, but can still be accessed online at
    Thanks again to mDoolin14.

    You start with 50% readiness, and gain a few % for every Multiplayer Game that you complete. Ive played about 13 Broze Levels (~ 25 Min one Map), my N7 Rating hit 40 and then the Achievement came up.

    Equinox83 : If you let the game select the map for you - I think the option is "unknown" sector, then you will get a small % for each sector simultaneously. Whereas if you actually choose a specific map, then you will get a much larger % but only for that sector.

    RhyoliticThis MP is complete and utter horseshit. Excessive amounts of xp to level up (12k to get to level 2? Srsly?) combined with shitty maps, grenade spamming twinks and zerg rushing enemies. Ya, that's fucking fair.

    crowbo 360I enjoy the multiplayer. It gives me a chance to play with different character classes to what I usually select.

    I nic I knack II don't understand the complaints. This multiplayer is a perfect fit for the game. Anyways. starting at 50 % , each match played on unknown location/unknown enemy is +3% for all five sectors of the map. So 17 matches need to be played, add one for each day (3% will be lost). Playing casually is is obtained in about the first week if you play three-four matches a day. Sounds pretty simple. As for those not enjoying/hating on the multiplayer, maybe your just not meant for the game, i don't know what to tell ya, all i know is that i'm really enjoying every part about it.

    This achievement requires 100% readiness in all sectors for Galaxy at War. At the beginning of the game, the Galaxy at War display on the main menu says that all sectors have 50% readiness. These percentages cannot be increased through the single player campaign. In order to increase readiness, you must participate in cooperative multiplayer, play the iOS game Mass Effect: Infiltrator, or use the iOS Mass Effect Datapad. The most effective way is to repeatedly win bronze matches until the readiness reaches 100%. Each successful match includes ten rounds followed by extraction and can add anywhere from 1% to 7% to a given sector depending on the map you're playing. This can take up to ten hours of playtime depending on the skill level of you and the people you're playing with.
