How to Unlock Different Swords in Katana ZERO
In Katana ZERO there are five swords you can unlock by collecting hidden keys throughout the various levels in the game. These keys are hidden and can be hard to find. Below I will show you how to unlock different swords in Katana ZERO.
How to Unlock the Gov’t Lab Level
To equip different swords in Katana ZERO, you need to unlock a twelfth level called the Gov’t Lab. This level houses all the swords. To access this level, grab the keycard off the Psychiatrist’ body during level eleven. The new level will appear on the level select screen. Note that you can only have one sword active at a time.
How to Unlock the Prism Sword
Sword Description: “The world is you canvas and blood is the paint.”
Sword Effect: Makes enemy blood come out as a random color.
To unlock the Prism Sword you need to collect the Prism Key which can be found in the opening of the game. This key is on the body of an enemy to the left of the area you drop down into as soon as the game starts. Loot the body to get the key.
How to Unlock the Sword of Masters
Sword Description: “Shoots and otherworldly beam when charged.”
Sword Effect: Shoots a beam when charged up.
To get the Sword of Masters you need to kill the target in the Murdower Hotel using the statue before the balcony. When you grab the statue, open the door to the balcony and throw the statue at the guy standing there. Loot his body to get the Master key.
How to Unlock the Savant Knife
Sword Description: “A short blade with an extremely quick attack.”
Sword Effect: A shorter range sword that allows you to attack quicker than the katana.
Getting the Savant key is a bit of a process. On the Slaughterhouse level you need to avoid waking up the Leon character (the one who talks to you on the tv screens). This requires avoiding three events the events are as follows.
Savant Key Event 1 – Cut Wire
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.
Savant Key Event 2 – Avoid Cameras
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.
Savant Key Event 3 – Avoid Cameras
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.
How to Unlock the Claymore Prototype
Sword Description: “Giant cleaver that crushes bullets and defenses.”
Sword Effect: A large sword that swings slower than the katana but has wider range and destroys armor.
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.
How to Unlock the Phoenix Edge
Sword Description: “Cuts through foes with the phoenix’s flame slice.”
Sword Effect: Launches a flame after each strike.
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.
