The superficial concept is that Shepard is rebuilt of synthetic parts and assembled with technological items thanks to the Cerberus Project. you are a synthetic too! (or something with this concept) Something that the little VI guy says in the final mission.

When you play Mass Effect 3 again, load that new save file and play the ending again.

Click on the number and just change it to something like 12000. That number is your military strength score. On the right, you'll see 'Id 173' and below that, 'Strength' and a number. The first value highlighted is 0 on the left.

All the way on the right side, you will see a '.' button.

Now scroll down and look for a line that reads 'GAWAssets (Collection)'.

Scroll all the way down and you will see a line that says 'Player'.

The player tab should be blank (this is normal).

(The Mass Effect 3 save file location is in the My Documents folder under the Bioware/Mass Effect 3/Save directory. Find the save file you want to edit and double click on it to load it into the program. EMS is Galactic Readiness percentage x Total Military Strength (achieved through War Assets).

EMS, or Effective Military Strength, is the deciding factor in whether or not you get the Perfect Ending showing Commander Shepard waking up.

However, it is not the deciding factor on whether you get the Perfect Ending with the clip showing Commander Shepard waking up. It can only be increased by playing multiplayer.

Galactic Readiness percentage is, by default, 50%.

To clear up confusion regarding Galactic Readiness: Clear up the Confusion! Galactic Readiness or EMS? Playing multiplayer and building up your Galactic Readiness can double the effect of your Total Military Strength, but you can also achieve enough War Assets on your own tp make multiplayer unnecessary.

The Galactic Readiness percentage can only be increased by playing multiplayer. So, if you have 5000 Total Military Strength and 50% Galactic Readiness, you have 2500 (5000 x 0.5) Effective Military Strength. EMS = Total Military Strength x Galactic Readiness percentage.
