How to unlock the Plans Refined achievement in RAGE - Definitive Guide
Story related and cannot be missed
I advise you unlock the "Wall Hack" and "Rebar Pie" trophies during this mission.
This is a fairly short mission and won't take you very long to do. All you have to do is go to the refinery and steel the plans for something called "Firestorm", which you find out is a flying gunship.
