Portal 2 surpassed my fondest expectations. I was surprisingly amused with the 1st installment and utterly enthralled with the sequel.
This an absolute gem of a game. Lost of surprises and challenges along the way. Who would have thought that the evil AI would go through such a dramatic transformation?
The co-op is great, though here in Brazil it is hard to find a regular partner to play through the game.
I am really grateful to have played such a marvelous game and wholeheartedly recommended this to anyone.
