Sifu

The Museum is the third level of Sifu.

EDIT: @SystemeD10: "Be careful, it seems that activate cheats when pick up item avoid achievement.
I guess I have to restart a new game and earn this items with no cheats"

EDIT2: Please check the SiFu forum on TA about modifiers and achievements: Modifiers

To unlock the achievement you have to find the 17 collectibles. Some of them are automatically unlocked as you progress through the level. I will list them anyway.

Below is the board collectibles with numbers:


Collectible #1 - Club Code - You need the Museum Keycard first.
On the third floor, you encounter a female combatant with blue hair. You got this by killing her.

Collectible #2 - Exhibition: Identity - At the start of the mission and after killing the first 2 guys, take the hallway on the right and collect the pamphlet on the stand before entering the first room

Collectible #3 - Security - This entry will be added to the board by killing the first two enemies of the level

Collectible #4- Family Photo - In the room you access by opening the Artist Residence Door (#17). You will need the Artist's Key to open the door (mission The Tower, #14)

Collectible #5- Museum Map - In the atrium at the beginning of the level, next to the ramp on the right-hand side. You will find a stack of maps

Collectible #6- Kuroki's Inner Circle - You will encounter these two enemies with glowing feet, in a dark room. This is just before the boss fight

Collectible #7- Strange Mask - Same place as Club Code (#1); simply interact with the mask the blue-haired fighter was looking at

Collectible #8- Stairs Access - Ground floor: attempt to open the glass doors along the back wall to add this entry to your board

Collectible #9- Exhibition: Cycle - 2nd floor: you will fight Disciples of Sean's Army (#12) in a room with coloured light bulbs. The collectible is located before this room, in a hallway similar to #2

Collectible #10- Bodyguard - Automatically given the first time you play the level. You encounter an enemy with Juggernaut-type moves, and unlock the entry upon defeating him

Collectible #11- Elevator - At the beginning: across the Stairs Access doors (#8), try to interact with the elevator

Collectible #12- Sean's Army - Defeat the two Disciples in the room with light bulbs. This is after collecting #9

Collectible #13- Museum Keycard - Automatically unlocked once you defeat the Bodyguard (#10)

Collectible #14- Temporary Exhibition - On the fourth floor, head past the dragon shrine and collect the pamphlet on the stand BEFORE you vault over the barrier that leads you to the Temporary Exhibition

Collectible #15- Elevator Key - Acquired after completing the Temporary Exhibition

Collectible #16- Exhibition: Twins - 3rd floor: collect the pamphlet from the stand (same as the two others), before reaching a room with fighters and Juggernauts

Collectible #17- Artist Residence Door - Upon arriving at the fourth floor, turn right and head through the first set of doors. Look to your right and interact with another set of double doors. You need the Artist's Key from the Tower (Mission4, #14) to unlock this
