Katana ZERO: All Achievements Guide & Checklist

“Most people go right. You went left.”

To get the Prism Key item and achievement, start the factory mission and go left instead of right as soon as the mission starts (you will need to jump on a couple of buildings to get back up to the area. Loot the body on the far left to get the Prism Key.

“In 1962, the Orlons released one of the all-time greatest doo wop hits, Don’t Hang Up. Google it. Anyway, you hung up your phone a lot.”

At the beginning of the game you will receive a phone call in a hallway. If you want to unlock an achievement, simply continue hanging up this phone call (this is done by selecting the hang up choice) until the person on the phone gets angry. This will unlock the Don’t Hang Up! achievement.

“You stopped a suicide. With a murder.”

Pick up the statue before the target (seen above) and throw it at the target after opening the door but before stepping out onto the balcony. This will kill the target. Loot his body to get the Master Key item and achievement.

At the end of the Murdower Hotel mission you will arrive on a large balcony. Jump off the balcony to get the what a bad idea achievement.

“This will go well…”

To get this achievement you need to playthrough the Club Neon mission. During this mission you are told to not speak with the DJ. Speak to the DJ to learn about the drugs and see him get shot. After the mission is over, speak with the psychiatrist about the drug. Keep refusing the drug until your are told to leave. You will get the achievement.

“Fulfilled your secondary goal in the prison.”

During the Prison level, don’t kill a single police officer (or kill all the police officers if you refused the drug). After the mission you will find the Prototype Key waiting near your apartment.

“Why did you think it was a good idea to give him your Katana anyway? .”

Give your sword to the guy in the stretch hummer limo and then beat the opening room of Studio 51. Retrieve your sword by the elevator to get the achievement.

“You killed a suspiciously familiar character on the Quiet Hills set.”

During the Studio 51 level, you will enter the Quiet Hills set. After you pick up the blue keycard and head back to the elevator you will run into a coffin headed enemy. Kill the enemy to get the Coffin Head achievement.

“Poor guy.”

During the Studio 51 level, you will enter the A Space Uncertain set. On this set there is a robot. The robot will speak to you about being programmed to kill all humans. Spare the robot’s life. Complete the set (get the yellow keycard) and return to the robot. The robot will thank you for sparing it. It will self-destruct. This will unlock the No Love for Robots achievement.

To do this easily roll to his back when he is shooting and attack it. You can reload the boss fight at any time by going to the main menu, selecting continue and then continue from previous level.

“Found what the robber left behind.”

In the mansion level there is a large area with multiple rooms. Inside one of the rooms you will see a robber going through something on the floor. Leave the robber alone. Clear the floor then just wait for the robber to leave. Go into the room the robber was in and interact with the sack on the floor to get the Phoenix Key item and achievement.

“Meet your final end in chinatown.”

“Complete The Dragon’s tape.”

After you make it out of Chinatown alive, you and your neighbor will go pick up some movies. During this cutscene you will fall asleep. This will put you into The Dragon’s Tape which is the events of the prison, prior to you arriving there. Complete the tape to unlock this achievement.

“Didn’t wake up Leon.”

The Savant Key is the hardest key to get in Katana ZERO as it requires avoiding three different events during the Slaughterhouse mission. These three events involve a character named Leon (he’s the one on the TV screens). To get the key you need to avoid waking him up. The three events are as follows.

In this room you need to cut the wire before Leon locks you in. You have a few seconds to react once the door is opened. Cut the wire and continue deeper into the level. You know you’ve done it correctly if you do not get sniped in the next rooms.

In this room you will see four cameras on the ceiling. These cameras can be avoided by rolling into the center area then rolling past the last two. It is kind of a pain, but you can continually restart until you get it. If done correctly, Leon will not appear on the screen and you will not have to fight any enemies.

The final event takes place right after event 2. Like event 2 you need to avoid the cameras in this room and make it to the other side. Once you do this, the Savant Key can be found in the area below with all the explosives.

“Found all the hidden keys.”

Collect all five hidden keys in Katana ZERO: Prism Key – Level 1. Master Key – Level 2. Prototype Key – Level 3. Phoenix Key – Level 7. Savant Key – Level 11. These keys open up doors in the Gov’t Lab level (level 12). You get the key to this level off the Psychiatrist in level 11. Behind each door in the Gov’t Lab is different swords.

“Your trap card was activated.”

To get this achievement is a two parter. First make your way to the Murdower Hotel and speak with the receptionist there. During this interaction you are going to tell her the following.

1. I’ll just be on my way.
2. It’s called cosplay.
3. Obviously Shinju Sakamura from Ex Vs X – Sakura reDUX 2.
4. Childrens card games in a cyberpunk dystopia.
5. Uh, sure.
6. Thanks.

After you’ve spoken with the receptionist, complete the level. At the end she will cover for you with the police calling you Shinju Sakamura.

Now that the receptionist knows us as a cosplayer, make your way to the bunker level (level 10). Before you enter the bunker you will run into the receptionist once again. Tell her the following:

1. Can I just go?
2. I can’t show you my ID card… But I can show you my trap card.
3. Heh, it’s a challenge alright.
4. Throw out whatever card you want.
5. Throw out whatever card you want.
6. You just activated my trap card.

Upon the defeat of the receptionist you will receive this achievement and the joy of crushing your opponent in a children’s card game. FeelsGoodMan.

About halfway through the buker level (level 10), there is a molotov on a table by a melee enemy. Grab the molotov and clear the room (don’t use it). Enter the next elevator down and throw the molotov against the wall/ceiling so it kills you. You will get the Funny Prank achievement.
