The P190 SMG is a modified FN P90 that is designed to fire non-lethal rounds.
The P190 SMG is a P90 that has been modified to fire non-lethal sticky shockers that temporary stuns the target. Spies use it in the Spies vs Mercs multiplayer mode where it can not only stun Mercenaries, but it can also scramble the Mercenaries' electronic equipment. It has infinite ammunition, but requires a cool-down period between shots.
- The 'Sticky Shockers' that the P190 SMG fires are more similar to the Airfoil Round than the Sticky Shocker used in the single player aspect of the Splinter Cell games. The biggest difference, however, is that the Sticky Shockers fired from the P190 can never be used to knock out a target, only simply stuns them.
