This mission comes after the intermission mission "Remember". Meet with Jordi in Gorman Heights then climb up the patio to trigger the scene. After that, head to the rail yard. Make sure you’re prepared since you’ll deal with armed gunners again. You can climb down the patio to the docks below and head to the next location via speedboat or swimming.
Once you’re in the perimeter. You can do a ctOS scan or use the cameras to tag the enemies. Move from cover to cover and take out the enemies. If you have a silenced weapon, then use it to your advantage. Jordi will help you snipe out more enemies. Make your way to the gate, only to discover that it’s locked. Open your Profiler and trace the line to the switch console. Unlock it and enter the building to trigger a scene.
After the scene, more fixers will arrive. Like before, you have the option to escape or kill them. The enemies will be coming in from both sides. Your position will be vulnerable so choose a direction and head there. That way, you’ll prevent the enemies from flanking you. More enemies will converge and will attempt to overrun you so make your way to the right where there’s an exit waiting. Take note that the enemy chopper has a sniper on board so you have to be careful as well. You can take that sniper out using your own sniper rifle. Make sure to activate Focus to get more accurate shots. After downing the last fixer, the mission is complete.
