Each theater of war starts at 50.00% readiness. First click on one of the five theaters on the Galactic Readiness map:
- Terminus Systems
- Attican Traverse
- Earth Systems Alliance Space
- Outer Council Space
- Inner Council Space

Next click on one of the 3 missions. The missions will take either 1 hour, 3 hours or 5 hours to complete and offer increasing amounts of Readiness Rating as a reward. You can only have 5 missions running at the same time, so it is best to choose a 1 hour mission from each theater, unless you are going to be away from your computer for more than 5 hours, in which case choose the 5 hour missions.

When a mission has completed, you can collect your reward and start another mission. When all theaters are at 100% readiness, load up Mass Effect 3 while connected to Xbox Live and you will get the achievement at the main menu. It is possible to go from 50% readiness to 100% readiness in less than 20 hours if you are able to start new missions every hour. Be aware that readiness drops over time, so it is best to do this over as few days as possible.

You can also increase Galactic Readiness by completing N7 Special Ops missions in Mass Effect 3 multiplayer, or by recruiting Cerberus Escapees in Mass Effect: Infiltrator (WP) and (iPad).

This method is also useful for raising your Effective Military Strength, required for

You can easily blast through the first waves with 4 people and even if you loose at later waves it will go up at around 4 %.

VERY IMPORTANT = to find a game you should download all the free map packs.
