This news comes as I have finally had time to play the first game, and it was great. Valve has officially announced that Portal 2 will be released, and will be available October 26 for PC and Xbox 360. Some details have begun to spring up, however. Portal 2 won't be a mere addition to the Orange Box this time, and will be a standalone game, with a standalone price tag. With a $50 price tag, the game is sure to pack in far more content than the previous game. Some of the best news comes in the form of co-op multiplayer, which could lead to puzzles being easier, or the puzzles being more difficult. It would be interesting to see Portal 2 have head to head multiplayer as well.
