Katana ZERO All Achievements Guide

Chapter 1

Prism key
Just at the start of Chapter 1, after you kill the two gunmen, come back to search the first one’s corpse. You will get the Prism Key.

Don’t hang up!
In Chapter 1, during the first phase, repeatedly hang up when the psychiatrist calls you, until he gives up. You will then receive the achievement.

Chapter 2

Master key
In Chapter 2, on the last floor, you must kill Josh Rose. Don’t approach him or you’ll trigger the dialogue and he will jump off ! You have to toss an item at him, you can do it from a safe distance. If you fail, just restart. Once you’ve succeeded, search his corpse and voilà !

What a bad idea
In Chapter 2, when Josh rose is dead, simply jump off the balcony yourself.

Chapter 4

Prototype key
This one depends on whether you took your medicine before entering the prison. If you did, you will need to avoid and spare all the cops, but if you didn’t, you will have to kill them all. Basically, just do what the phonecall at the beginning tells you to, and when you get home, you will find an obvious suitcase with the Prototype key in it.

Chapter 5

Party Animal
At the beginning of Chapter 5, instead of visiting your psychiatrist, you will go inside V’s limousine. When he asks you for your sword to do a line of drug, accept ; you will not get it back until you reach the elevator at the beginning of the level, which is when you will get this achievement.

No love for robots
In Chapter 5, go to the second floor (A Space Uncertainty), and do not kill the robot ! Just go get the keycard, and listen to his entire speech on your way back to get the achievement.

Coffin Head
In Chapter 5, after having retrieved the keycard on the third floor (Quiet Hills), you will come across Coffin Head on your way back -it’s actually kinda scary. But he’s just cardboard, so slash him in half to get the achievement. Also, play Silent Hill 2.

In Chapter 5, you must “win” the battle against V in Chapter 5… although it ends the exact same way as when you “lose”, with Snow showing up. Here is a video on how to do it (read the description !)

There is a spoiler video about Beatdown achievement. Here:

Chapter 6

Phoenix key
In Chapter 7, you will reach a part where there is a burglar in the top left room. Don’t open the door or he will stop to take a defensive stance ! Just wait until he is done scavenging the purse, which will take almost all of the level’s timer (better kill all the enemies in the meantime). When he is done, search the bag and you will get the key.

Chapter 7

The End
At the end of the gameplay phase in Chapter 6, choose to die. This doesn’t have any lasting effect on your savefile, don’t worry.

Chapter 8

The Dragon’s tape
Simply beat Chapter 8 to earn this achievement.

Chapter 9

Savant key
Did you know you can skip almost all of Chapter 9 ? Watch for sensors on the ceiling, these will trigger the screen and traps when you pass under them, but they won’t detect you if you roll past ! You must not be seen by the ones above the equipment Leon blows up to get this key.

Chapter 10

Funny Prank
In Chapter 10, kill yourself in an elevator, which can be done by throwing a molotov cocktail at your feet. Make sure you do it before the elevator stops or your inventory will be reset !

Chapter 11

To be continued
Just beat the main game (this means the Mask of Life route).

Several chapters

Refused medication
First, you must disobey and listen to DJ Electrohead in Chapter 3, he will tell you about a drug he took. Mention it to the psychiatrist at the beginning of Chapter 4, and keep asking him about it until you get the option to refuse your medicine. Make sure you keep refusing until he asks you to leave.
Note : Not taking medication makes you suffer from withdrawal during Chapter 4. Your target’s dossier will change, and when receiving the phonecall, the Mask of Death will speak to you !

Forbidden Ultimate Danger Tempest-Eyed MAJORDOMO Imperial Barrage Crab, Evixion
First, tell the receptionist in Chapter 2 that you are cosplaying as Shinju from the Sakura anime, a card game anime. Make sure she lives at the end of the chapter ! You will need to talk to her again at the beginning of Chapter 11 : you must then ask her to let you go, tell her you can show her your trap card, and accept her challenge. Anything you say in that dialogue from there will get you the achievement.

Secret hunter
This achievement is unlocked by finding all five secret keys (see chapter 1, 2, 3, 6 and 9).
Note : Each key unlocks a new sword in Chapter 12, the government lab. You must search the psychiatrist’s body in chapter 11 to access it.

We thought you would have to do everything to ….. off the psychiatrist for this… but actually, all you need to do is refuse your medication in Chapter 4 (see Refused Medication above), and then talk to him at the end of Chapter 11. I tested the other variables and they don’t have any effect on the encounter.
