The Prototype Weapon is one of the most powerful hidden items in the game, but it is also one of the easiest to miss. This article will guide the player on how to obtain a prototype weapon and complete the “What’s This?” trophy in the game Code Violet, released on 12 December 2025.
How to Get the Prototype Weapon
To get the Prototype Weapon, you first need to find the Secret Key in the Bioengineering Lab. After you clear the first corridor, step into the next room and look for the large glass windows along the walls.
Shoot or hit the glass to break it. Behind it, you will find the Secret Key.
After finding the Secret Key, continue playing until you reach the final chapter and arrive at Starbridge Mansion. Once you enter the mansion, head inside and take the staircase on the left. Go up to the upper floor, where you will find a locked door at the top of the stairs. Use the Secret Key to open it.
Inside the room, the Prototype Weapon will be waiting for you. It is one of the best late-game weapons.
