Portal 2 is looking up quite nicely.
I really liked the first one, one of the great FPS surprises of these last years.
Who knew it would become that popular? Probably nobody expected such a reaction from the public!
Anyway, Valve's been twickin' the sequel.
Now with more puzzles!
Longer campaign!
More difficult!
More twists and surprises!
More plot!
And now with co-op!
Neat! A playable co-op mode in a side story, from the point of view of two bots!
