Represent entire series of Portal games. Portal™ is a puzzle game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative games on the horizon and will offer gamers hours of unique gameplay.
Portal comprises a series of puzzles that must be solved by teleporting the player's character and simple objects using the "portal gun", a device that can create inter-spatial portals between flat planes. Travelling through portals maintains an object's speed, thus several puzzles require "flinging" the player-character or objects out one portal by gaining speed, such as by falling, before entering the other one.
