Portal 2 (PC)

Another game created by Valve, Portal 2 the sequel to Portal (2007) released on April 19, 2011. Portal was initially packaged as a bonus game concept on the "Orange Box" and was met with overwhelming approval. Portal places the player in an Aperture science laboratory (A competing company to black Mesa, the main company of the Half life series), in a series of seemingly simple puzzles to get the player used to the controls and concepts of testing equipment. Soon they introduce portals, a two way gate that can be moved to any white wall by firing a portal from the provided gun. After completing the first game, Valve released a teaser of the character being taken back inside after escaping (And being knocked unconscious). Portal 2 was significantly longer and introduced Co-Op testing. The problem with puzzle games is that once you learn a solution, the puzzle is no longer fun. If you are playing on a console, once you beat the game (and the separate Co-Op story) there is nothing left for you to do. On the PC however, Steam has made mods easily accessible through Steam Workshop. Allowing anyone to download custom maps without needing to understand how to install mods. Valve promised that they would release a easier to use map editor than previous editors (New version shown above). Currently the quality of the maps is generally high, with difficulty ranging from low to impossible. Players can also create custom storys with audio. Because portals are involved, levels do not have to make sense, a box from one side could take you to the past version of a level, the other side the future, with the middle being made out of ice-cream.
