Dusk Diver 2

Story-related and cannot be missed.

This trophy is for completing Chapter 7, "Teenagers' Blues". It's another relatively short quest story-wise, but you've also got a handful of new side quests to complete, including a missable Companion Quest. For the story quest, you'll bounce around a lot in between locations, but for once, you won't be unlocking any new ones.

That said, you'll have to visit the Beimen Passage here which contains a very similar Maze to last Chapter's trap in the SCCP's Underground Passage, so hopefully you were able to get the knack of it in last time. It works exactly the same way and even the rooms and passage look fairly identical. Once again, it's strongly encouraged that you take the time to even go against the maze to pick up all of the collectibles before leaving.

Note: Once you start the main quest proper by going to Beimen, you'll need to continue it through to the end as you'll hop from location to location, so you should complete this Chapter's side quests first.

After you finish Beimen Passage, you'll immediately enter Civic Boulevard, to a new section you weren't able to access before. There are quite a few collectibles here to grab as well. Finally, once you reach the end of the Boulevard and take down another Dragon Vein Control System, you'll head into Dadaocheng (Youshanding). Be wary of the floating red squares on the ground. Stepping on one activates an alarm and you'll have to fight off a wave of enemies. While the squares are avoidable, they're kind of a pain. Each pair has a pattern that you'll need to exploit to get past them. Whether it's worth it to take the time to do so or not is up to you.

This is (finally) the last location for this Chapter, so you'll face this Chapter's final boss at the end. To complete the Chapter, return to the Tumaz Mart for a brief cutscene, after which you'll earn this trophy.

BOSS FIGHT: "KUNLUN TRANSFORMER. CENTRAL TYPE"
This boss is a large, almost angelic-looking robot, with a sword for an arm. It's not that tough of a boss, just be wary of its teleportation skill and its charge. For the former, it shoots up into the air, where you can't attack it. After a few moments, it drops down. When it does so, make sure you're far away, because the hit box is quite large. Otherwise, it's got a few standard attacks, like shooting lasers at you, swiping with its sword, and so on. All in all, it's nothing special; it's a rather standard boss for this game.
