Refuge To get this achievement you must survive an evacuation which is toward the end of the match, you must get to the evacuation point without dying, I would recommend using the camouflage ability if you have it and retreat immediately. You must be on the losing team to be able to evacuate, if winning your job is to kill the people trying to evacuate.
Don't die though, because you only have 1 life to get there. Worst part is the enemy team really wants to kill you because there is an achievement to kill all pilots trying to evacuate.
If you are having problems evacuating, you can call your titan after it says "Epilogue" and go directly below the dropship once below it just hit up on your D-pad and manually eject into the dropship.
