Portal 2, gaming company Valve's sequel to the popular first person puzzle game, takes place about 200 (unapproximately) years after the events of the first game. The first Portal game was compiled with two other games Team Fortress 2 and the Half-Life 2 franchise, on one disc. The story arcs of Half-Life and Portal are intertwined, and of course, continues on into Portal 2. Valve, being the clever geeses they are (that's right, I said geeses), their connections together are only hinted through lovely easter eggs throughout both games. Or you could just wiki the storyline... Your choice.
Anyways, moving on with the review. The graphics are stunning, as they were on the first game, though that is how it should be since you are not doing things like fighting continent sized bosses nor conjuring up phantasmal displays of flashy black magic. You are a girl, with a gun, with a mission. GET THE H OUT! The gameplay keeps true to the first game - as I said before your mission is to get out, through the use of shooting multiple portals to make things happen, and then walk your (fine) self on through. GLaDOS does not skip a beat so I would highly suggest keeping your ears open because she has quite a lot to say about the things you did to her the first time around (LOL). The storyline is compelling and keeps you glued in 100% of the time. In addition, the puzzles get pretty clever and some will just plain ol' piss you off, helping to keep you focused on the game. Overall though, they keep your attention for hours, I just wish there were more. I finished the game fairly quickly, both the single player story and the online co-op mode.
For the rest of my analysis of Portal 2, hit the break.
