Its been 20 years since the release of the original Half-Life. While an official successor to Half Life 2 is still nowhere to be seen, fans are carrying on the game's legacy in place of Valve. The Project Borealis team is working on a continuation of the story, while Black Mesa brings the original game up to modern standards. Check out the "Xen" trailer the Black Mesa devs released today here. To celebrate the 20th anniversary of the release of Half-Life, the long awaited final chapters of Black Mesa are shown in motion for the first time! Xen is targeted for release in Q2 2019.
