Clubbers - Automatically unlocked as soon as you enter the main room
Collectible #2 -

This is the other door, right of this one

The Three Trials Notice - Later in the mission you reach a dark hallway where people are training. You see a guy in front of the door at the very end of this hallway.
Do NOT attack anyone here, instead talk to the guy and press
for the "Trials?" option.
Collectible #10-
Hacker's Key - First you need to unlock Jinfeng's computer in mission 4: The Tower. Then, go speak with the Tech Guy (see #14] and select

Collectible #11-
Fire Key - Behind the door #6 are two disciples. Kill them to get this collectible
Collectible #12-
Sean's Values - Near the end of the mission you reach a burned area (cannot miss it). You need to read the
three signs on the walls to get this. They are highlighted with a dot.
Collectible #13-
Fire Chest - Right after #12, continue until you go down some stairs. You can see the chest in front of you. You need the Fire Key to open it (#11).
Collectible #14-
Tech Guy - In the corridor after Access Door (#4), go straight to unlock a new shortcut. From there, go upstairs and kill all fluo guys you meet. In the back there is a small room with a non-hostile PNJ, that is the Tech Guy. Once you get Jingfeng's computer from the tower, you can talk to him to get the Hacker's Key (#10).
