Portal 2 proves that sequels doesn’t have to be lazy cash-ins on the original games success. Everything in this game has been expanded and made better in some way and playing it is a blast. The humor and dialogue are spot on and the puzzles, while not too complicated for veteran players, still have a few head scratching moments.
Gameplay: More story, more puzzles, more of everything.
Graphics: A vast improvement over the original.
Sound: Outstanding voice acting all round
