Messages: 3/5- There’s a lot of talk of killing in this game. Both main characters attempt to kill you throughout the game and talk about it in violent ways. But by the end, things change, and you work together.
Violence: 2/5- You can get mashed by “mashy spike plates,” killed by poison gas, and shot by automatic turrets.
Sex: 0/5- Nothing.
Language: 1/5- Mild language, such as d-mn and h-ll, throughout.
Overall: Portal 2 is one of the greatest games ever made. It has a great story, amazing dialogue and fantastically crafted characters. It has a slightly disturbing and creepy atmosphere, and the ambient music perfects this. The game has an increasingly interesting and strange story, until the breathtaking, epic finale. After the 10-12 hour single player game is over, you can continue the story with co-op mode. Portal 2 is unbelievably good. Ages 11 and up should be ok, because of the mild language, creepy atmosphere and mild violence. (and sheer epicness) :D
