The original Portal was basically a tech demo, included as a bonus alongside other titles in the Orange Box. And that was all it needed to be. However, it turned out to be full of dark humour and featured a computer that is one of the greatest villains/characters in any video game… ever!
Now, though, Valve have produced Portal 2. The sequel includes a cooperative campaign in addition to having twice the content in the single player campaign. This is probably the most anticipated game of the year, and if anyone can live up to the hype, its Valve. But have they done it?
