"We're excited to unveil Half-Life: Alyx, our flagship VR game, this Thursday at 10am Pacific Time," Valve tweeted. "Can't wait to share it with all of you!"
The first Half-Life game came out in 1998, at the time being called "revolutionary" by CNET sister site GameSpot. Half-Life 2 dropped in 2004. Since then, we've been waiting for a third installment of the franchise while Half-Life 2: Episode One dropped in 2006 and Half-Life 2: Episode Two in 2007 as shorter games.
