Half-Life Universe Timeline

What’s on the Half-Life Universe Timeline?

We call it the Half-Life Universe timeline because it started with the first game, Half-Life, one of the most innovative games of the 90s. It since grew into a shared universe with the Portal games, which take place in the same timeline (though Portal 2 is in the far future). The games have been named as some of the best video games of all time, and there is even talk of a movie from producer J. J. Abrams that could tie-in with the next game (if there ever is a next game).

What we have isn’t much; there aren’t any additional comics or books either. Just the games. But there are a number of expansions to some of the games, so all of those are listed here in chronological order.
