Portal 2 co-op review

Portals 2's co-op feature is like the single player version but with two people. It's fun to play with a friend or enemy. You have to complete puzzles and other challenges in order to move on. There are lasers and turrets. It's fun to get side tracked and kill your partner (a bunch). There is a faint story behind all of the puzzles. You have to open a big vault to free humans to test more. GLaDOS is once again voiced by Ellen McClain which is very good since she did an excellent job on the single player. She is the only voice except for little sounds which come from the robots you are playing. It was well done and I give this a 8.3/10
