Waiting on Half-Life: Alyx? You’re not the only one. Valve has decided that for the time until the game launches, you can play the entire series for absolutely free on Steam.

Valve made the announcement on Steam that Half-Life, along with its expansions Half-Life: Opposing Force and Half-Life: Blue Shift, Half-Life 2, Half-Life 2: Episode One, and Half-Life 2: Episode Two, and Team Fortress Classic are free-to-play until Half-Life: Alyx launches on Steam VR March 2020.

Obviously, if you’ve never played one of the landmark games in gaming history, then this is your chance. You’ll need Steam to play the games, but you already knew that.
