Fans of the Half-Life series have been dreaming about the fabled Half-Life 3 for many, many years. So long, in fact, that they gave up and switched from dreaming to joking about it years ago.

But while Half-Life 3 is still just as much of a pipe dream today as it was yesterday, Valve has announced a new game in the series titled Half-Life: Alyx. The game is a full-length virtual reality title, and it’s actually both a prequel and a sequel set after the events of the original game but before the events of Half-Life 2.

An announcement trailer for the game was released today, and you can find it below along with more info.
