The insanely popular Half Life mod gets the Flash treatment! The title above is an edited version of the title graphic from Portal: The Flash Version, which used an edited version of the official Portal logo. This collection is not affiliated with or endorsed by Valve, but we hope they enjoy it as much as we do! And go buy the game, because it's amazing.
