Lets have a game review here guys. This is my first review, so if I fail, I fail.
Game play
Game play is simply awesome, what can I say? There's a story mode and a mutiplayer mode. The story mode is the first thing you want to do after you got the game. In the story mode you play as a random avatar, trying to pass giant puzzles. The puzzles are harder, larger and more exciting then Portal 1. And when I say larger, MAN! The puzzles are giant! About 10 times larger, well not all of them. Huge and hard puzzles, but when you sovled them, you'll say "I know that." The story of Portal 2 takes place after Protal one, so if you want to play Portal 2, play the first one first. Just to tell you, the story is very funny, you'll be going LOL or ROFL every 5 minutes.
Mutiplayer mode is when you and a buddy can play on different co-op levels designed so that only co-op can pass it. You and your buddy play as 2 robots. It's best to play co-op when you 2 can talk to each other, like on skype, you know, to unpuzzle the puzzle. It's great fun to play co-op with a friend because so that you are not *forever alone* all the time.
Graphics
Woot! Graphics is the best on Portal 2. Very HD-ish. Things look very..umm.. realistic in a futurerstic way. Graphics is simpily awesome, even if you do weird stuff in the game.3-D awesomeness.
Story line
As I said earlyer, the story takes place after portal 1. It starts off when you slept for cople of years and wake up to find a Stupid 1-eyed Robot to befriend you. And not only he talk stupid, look stupid... never mind. Anyways, he revives a robot that you killed in Portal 1 on "accident". The mother bot of the "place". And she puts you pass all types of test chambers to try to kill you. But you put your stupid 1-eyed robot friend in charge of the whole place. Play the game to find out more.
Overall the game is awesome, I give it a 6 out of 5. Goodbye.
