The reason for the Episode One label is that this is the first of several extension episodes to be released that continue the story. It places you back in the action from the precise moment at which Half-Life 2 left off, and you continue from there on. The best way to describe it is simply as an extension pack. It isn’t even an episode one in the Star Wars prequel sense you might expect. It isn’t really a mission pack and certainly not an entirely new game. Because Episode One is a funny fish all round.
