Laptopgun

Perfect Dark (N64)
In the Nintendo 64 game, the Laptopgun is an experimental weapon, using advanced microcomputers to run a fully operational laptop for digital warfare -such as virus injecting and firewall evasion- that can be folded in a specific way to create a small assault-rifle type device.

The weapon could also be further transformed into a sentry version, using the computer compoinents of the laptop to acquire targets and track them, firing the weapon at any hostiles.

The weapon it's self was designed, developed and put to use by the Carrington Institute.

Perfect Dark Zero
In Perfect Dark Zero, the Laptopgun (Referred to simply as 'Laptop' in this game) is a silver and black case, which is jolted forwards by the user to flip out the assault rifle components, and the handle/sight is pushed forward to load the weapon's clip into the breach.

The Laptop retains it's predecessor's abilities, as it can also be used as a sentry turret.

The turret will act as expected, targeting hostiles in it's view and firing at them until it sustains enough damage to explode, or it empties its clip.

A popular technique with this is to remove the sentry from a wall or floor, and reload it before placing it back as a sentry, this negates any previous damage done to the weapon and its clip is refreshed directly from your assault rifle ammo pool, thus granting it another 30 shots.

A sentry can be affected by the RCP 90's tertiary 'hack' function, and will subsequently change it's FoF LED from green to red and start targeting friendlies.

Oddly, the muzzle flash is fitting with the weapon's ascetic, of an amethyst purple.

Perfect Dark 3
In Perfect Dark 3 the laptopgun will serve as the protagonist's favoured assault rifle.
