|"The PS20 is a disposable, plasma-based weapon developed by an unknown security organization as a next generation stealth pistol. Unfortunately, the necessity of maintaining a small physical profile restricts the weapon to a single shot. Despite its limited functionality, the PS20 can be lethal at close range."|
|- description of the PS20, Deus Ex|
The PS20 is a very small weapon that shoots a single ball of plasma, which is similar to the one fired by the plasma rifle. However, because of the design, the weapon has only one charge and is useless after the only charge is depleted.
The PS20 fires a single plasma ball. The ball inflicts fire damage when it hits something. In addition, it will cause a small explosion, dealing additional fire damage to anyone inside the blast radius. After the gun has been fired, it will automatically be thrown away.
- The PS20 is useful for destroying weak doors.
- A headshot can defeat an MJ12 Trooper in one hit, but good aiming skills are required because it has only one shot.
- For some bizarre reason, only one PS20 can be carried in the inventory at any given time.
