WARNING: Some areas you will visit for this final trophy have an extremely low Frame-Rate so react appropriately.

This trophy is relatively simple up to a point as all you have to do is go through the trenches to reach the Pulse Field Control Centre, overload the Pulse Field, go to the HQ and kill General Jingwei. Now comes the hard part. If you have a high enough Speech Level then you can persuade Jingwei to commit suicide but if your Speech Level is too low then you will have to kill him, which is not easy as his main weapon is a powerful sword and he has lots of health. Regardless of how you get rid of him, General Chase will appear shortly afterwards and pull you out of the simulation and back to the real world.

Once back in the real world, re-equip everything you were wearing and using prior to entering the simulation. Drop any un-necessary items, make your way to the Armoury door terminal and use it to open the Armoury. The trophy will pop once Scribe Olin has finished talking to you.

Addendum: If you have started but yet to get the Main Game trophy called You Gotta Shoot 'Em in the Head, then there is a trick you can use to get it during this final Quest with very little work. All you have to do is after you gain access to the Armoury in the Outcast base, pick up the Winterized T-51b Power Armour then drop it and pick it up again. The trophy will pop once you've picked it up again, if you haven't started the mission then talking to Mister Crowley and accepting the mission will pop the trophy (credit to The Great American Savior, x410xDragon and Fordis for confirming this actually works and how to do it).

Note:

• The Winterized T-51b Power Armour you get from the Outcast Armoury is virtually indestructible so it's highly unlikely you will ever have to repair it.
