A simple explosive compound made of sodium and phosphorus.
~ Item description

UEX is an explosive in Barotrauma. It can be made in the fabricator with Sodium and Phosphorus.

Usage[edit | edit source]

UEX can be placed in a Detonator and then remotely detonated by sending a signal to it, typically by wiring the detonator to a button, but it could be triggered other ways. For example, the detonator awaits a "1" signal, so if you wire it to a door's state_out connector, the "1" signal is sent when the door opens. It is capable of causing significant damage to both entities and structures in the world.

Similar to C-4, IC-4, Compound N and Volatile Coumpound N it can also be loaded inside Railgun Shells and Nuclear Shells for added damage. UEX is the primary ingredient for fabricating various explosives, including C-4, grenades, explosive coilgun ammo, the nuclear depth charge and nuclear railgun shell.
