There is a crazy scene at the lighthouse tender’s house at Hisingafyren. There was clearly a big messy fight, dead runners outside and inside the house, bullet strikes in the walls, overturned furniture, etc. If you follow the apparent path of the fight you come to this locked door:
Has anyone been able to open this door? Is there a mission that reveals more about the events at this location? In my imagination there is an injured person in there waiting to be rescued, not knowing you have cleared out the robots.
