Review
I was a pretty big fan of the original Portal, but when I played it I finished it in one night. Fortunately Portal 2 has pulled out all the stops and delivered what the gamers want.
This game is packed with puzzles, memorable characters, nostalgia (For those who played the original Portal) and fantastic atmospheres.
If you are on the fence about getting a copy of Portal 2 let me just say. Get it. It's worth every penny and between the single player and co-op portions of the game there are hours and hours of gameplay to be had here.
