Pure chaos. I love every minute of this game. Get a group of friends to regularly play this with and it's just stupid fun all the way through. Highly recommended.

Portal, but more! Portal 2 is just as fantastic as the first, but in different ways. This game's narrative, aesthetics, and overall tone just enhance the experience more. I think I prefer the first one, just for the atmosphere alone, but this game doesn't stand far behind at all. It's aged like fine wine. The Co-Op mode is also absolutely fantastic, and is a ton of fun to replay.

I can't overstate my satisfaction enough. It's a truly fantastic game and was developed by college students! True mastery was achieved here and its inspiration is still felt in the industry today. One of my all time favorite games, easily.
