SS said, "When Valve first teased Portal 2 they did it with an update to the original Portal. The update came with very vague patch notes; it added radios that held messages to the game and it slightly altered the ending. Ultimately the game ended as Game Informer revealed Portal 2 would premier on their cover. Well, Valve has updated Half-Life 2 today."
