After unlocking the Gamma arena, you will be put back into Seattle with you 'Rocket' power. You will be given mission to destroy six drug trucks that belong to Shane. Basically all you have to do is find a truck using the satellites, kill all the enemies, destroy the drugs and tag the truck, then repeat five more times. You will then automatically be given the mission to fight Shane at this club. Once you get there a cutscenes will happen where he drugs you and everything will go really wobbly. Fight all the D.U.Ps as best you can until everything goes white and a cutscenes starts
and you will then have to follow some hallucinations until you are back in Curden Cay, crying. Augustine will ask you if you want to kill Shane and he will be there. You blast a hole in the Wall and everyone will escape. Shane will steal an APC. You will follow him and fight the D.U.Ps that appear. Be careful as your only source of neon energy are the drones you shoot down. Eventually you will catch up to Shane. Use R2 and the touch pad when prompted
the trophy will unlock during the cutscene that follows.
This is my first ever guide. Please give constructive feedback and if you give a thumbs down at least say why. THANKS!
