Jak II

This trophy is story-related and cannot be missed. This mission is obtained from Torn.

Torn will have you return to the Pumping Station. Head the same way as you did for the pump but there'll be a few lifts activated which weren't working before. Take them up and follow the new path and eventually you'll find Ashelin, an important Underground member. After a short scene, you'll be ambushed by Metal Heads. Take them all out (using whichever guns you wish or simply break out Dark Jak if you want a fast win) and afterwards watch the story-related cutscene.
