Volatile Compound N
From Official Barotrauma Wiki
Volatile Compound N (Nuclear) can be made in the Medical Fabricator with 1x Flash Powder and 1x Compound N. Unlike most explosives in the game, It has a durability counter that deteriorates over time. When the durability counter reaches 0 or below, it will have the explosion radius and effects of a regular Compound N. It can be considered a dangerous timebomb, and traitors can put it to good use on the majority of stock ships.
