PS20

"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 to PS20

The PS20 is a single shot self defence weapon that uses the pistol skill. It appears in Deus Ex.

Background
The PS20 could be related to the plasma rifle as a "smaller cousin," or could be a completely separate weapon system.

By 2052, the PS20 was designed to replace the 10mm stealth pistol, however it is restricted to only one shot due to its compactness.

Game item
It's hard to think of any actual use for this weapon. It has 100% accuracy but neither scope nor laser sight, so it would be difficult to use it past short range. The damage is not good enough to take out anyone without scoring a headshot. It can be used for breaking doors, though.
