Handheld Portal Device

The Handheld Portal Device model from Portal.

The Aperture Science Handheld Portal Device (also known as the Portal Gun or ASHPD) is the experimental tool designed to place two portals that objects can pass through. This is the primary tool players are equipped with to complete Test Chambers.

Overview

The Handheld Portal Device is designed to create and place portals on any white surface that is immobile, flat and large enough. When the device is fired, a colored projectile will be emitted from the barrel. If the projectile strikes a valid surface, a portal of the corresponding colour will be formed. If a portal of the other colour is already placed, these two portals will be linked. If a portal of the same colour is already placed, it will be closed and the new one will be used instead, limiting the player to the use of only two portals at a time. The glass chamber and a light on the top of the device will glow with the colour of the previously placed portal.

The Handheld Portal Device also has the ability to pick up and manipulate objects directly in front of it in the same manner as the Gravity Gun from the Half-Life series. It cannot launch objects like the Gravity Gun, but can carry heavy objects, even through portals.
