Portal 2 proves that sequels doesn’t have to be lazy cash-ins on the original game’s 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 provide a few head scratching moments.
Gameplay: More story, more puzzles, more of everything.
Graphics: More detail and variety than the original game.
Sound: Outstanding voice acting all round
