Portal 2

Portal was possibly the best Xbox Live game there was, and when I heard Portal 2 was coming out as a proper game, I couldn't wait. And it was even better than i'd hoped! Portal 2 introduces Wheatley, a funny robot who starts off as your friend, but then his power goes to his head and ends up as the main enemy. He's stupid, though, and his first level is easily the easiest level you'll come across in any game. His levels do get harder as you go along though, and in the end his levels are just as hard as Glados'. When you meet glados in this game, you turn her into a potato! She helps you all the way through though, because she still hates you, but she has to work with you to defeat Wheatley. This game also introduces gel, and there is red, blue and white gel, and the gel is like goo. Red gel makes you run really fast, blue gel makes you bounce really high, and white gel lets you shoot portals onto any surface that it's on. Also, you get to play 2 player mode in this game, so you can work together! You can go on online mode or split screen. You're 2 robots in multiplayer, and you have 2 portals each!

This is part 1 and 2 of the very end of the game, so if you don't want to see what happens right at the end, DON'T WATCH!
