These mechanics are extremely fun, and really make the player think about the endless possibilities they could create using the portals. Some great uses of physics can be found in the game, such as jumping from a great height into on portal, only to come out at high velocity from another portal, allowing form longer distance jumps. This allows for an interesting way to solve puzzles throughout each chamber, as the player will have to figure out new ways of reaching greater heights, traversing huge chasms and bend physics, to suit each of the tests. The Portal Gun itself uses two different portals, one blue, and one orange, which the player can travel between. Using the portal gun, you much complete each test chamber, using the portal gun in some creative and innovative ways. The mechanics of this game, like Half-Life, and the traditional style of Valve, are physics related. Behind the façade of humour and the promises of cake, Chell begins to discover secrets that shed light on the more sinister side of science.

Upon completion, your success will be rewarded with cake! Or so it would seem. The main tests you have to complete involve the new Aperture Science Handheld Portal Device, which you must use to complete various challenges which get increasingly harder as the game progresses. GLaDOS herself is both hilarious and sinister, and throughout the game we hear some excellent lines from her. You awaken from a sleeping pod, and are greeted by the main antognist, and sometimes helpful guide, GLaDOS, the Genetic Lifeform and Disk Operating System, as she tells you what is expected of you as a subject. You are a test subject named Chell, in the Aperture Science testing facility. So much so that it warranted Valve to create another version of the game Portal: Still Alive, with more content than the original, on the Xbox Live Arcade. To the surprise of everyone, both developers and players alike, Portal took centre stage as one of the most innovative puzzle games ever to reach any console. Portal, a first-person puzzle game designed by Valve, as originally designed to be a fun side game, packed together with Half-Life 2, the episodes of the same series, and Team Fortress 2.
