The Belgian Fabrique Nationale (FN) P90 is an unusual submachine due to its feeding system. Ammunition loads through the top with a 50 round magazine instead of the bottom or the side. It fires the FN 5.7mm round which is designed to defeat most forms of military grade body armor. The P90 is compact because it was designed as a Personal Defense Weapon (PDW). It comes with a red dot scope built in for fast targeting and mounting rails for easy attachment of flashlights and lasers. The P90 is used heavily by Henrietta as it seems to be her favorite weapon.
