Finally, Valve had the pleasure of releasing the Portal game for all Linux operating systems, through the Steam platform.Valve officially released the Portal game back in 2007, along with Team Fortress 2 and Half-Life 2. Some say that Portal has become one of Valve’s most successful game titles.
Today we are happy to announce that the original Portal game is now available on all Linux distributions that support the Steam for Linux client.
Portal is a first-person puzzle-platform video game, comprised of a series of puzzles that must be solved by teleporting the player's character using "the Aperture Science Handheld Portal Device."
