Alien - Sigourney Weaver harpoon gun used to shoot Alien creature out of the air lock at the end of the movie.
Aliens - Hero Pulse rifle - this was the fully practical version that contains both machine gun and shotgun - now decommissioned but still has that 'lock and load' slide action on the pump shotgun.
Aliens - Sentry Gun and power / ammo pack, spare ammo / power pack.
Smart Gun - Used by both Vasquez and Drake at different times - this is confirmed by the fact that the white lettering painted differently for each characters gun is still visible on the side of the gun - just slightly mixed as they have used it for one character and then over painted for the second.
