DON'T FORGET TO REHASH AND RESIGN!<br />
<br />
This is a save for the Savior Achievement.<br />
<br />
Just kill the last few guys to lure Gil.<br />
<br />
Then when you get to the console take the 2 keys - he will start talking - don't press the button to kill him (3rd option on the console after he stops talking).<br />
<br />
Just leave and head over to the elevator (get outside and enter the key into the fueling station).<br />
<br />
Achievement will pop as soon as you press the button in the elevator.<br />
<br />
This is taken from the Saveset Menov posted a while ago - i just post this in case someone needs only this achievement.
