Portal 2 is nothing short of a masterpiece. The game looks great, has snappy controls, brilliantly designed puzzles, and its dialog is some of the best in video game history. The game also doesnt pull any punches when it comes to its difficulty. Transitioning from one puzzle to the next prevents players from moving back and forth wondering where to go next. The puzzles are not overly complex, and everything the players do is at their disposal for each room.
