This is the 14th story progression achievement.
*** Spoiler - click to reveal ***Speak to Dogen in Crystal Valley to pick up the ‘Family Matters’ mission then follow the marker to Regatta Bay. Proceed through the building until you come to a large open room with several K-Sec. The best approach would be to take out the guards as you progress. There are a lot of them along your path including Enforcers and a Sentinel, but they are spread throughout smaller connecting rooms and walkways, which you can use to lose some or your pursuers if things start getting too much for you. You could try just running straight through the area following the path set by your Beat Link but it’s probably still best to at least thin out the guards' numbers.
Once through the room follow the path until you emerge in a lobby area with even more guards, including another Sentinel. Try luring some of them back into the corridor to take them out in a more isolated location. The Sentinel should follow you as a minimum, so take him out while you’re out of sight of the rest of the guards. Once he’s been taken care of you can take out the remaining K-Sec back out in the lobby. After that follow the path then take the elevator up. At the top of the building head to a terminal and activate it. After a cutscene head outside and run around the building to find a drone to jump onto – just make sure to move fast to avoid incoming VTOL fire. Once you land on the ground the achievement will pop.
