Black Mesa is finally finished after nearly 15 years of development. Black Mesa is, of course, the third-party remake of the original Half-Life featuring updated graphics and modernized gameplay. Black Mesa originally omitted Half-Life’s not-well-loved Xen platforming chapters, but developer Crowbar Collective recently reintroduced heavily-revamped versions of those levels. The new version of Black Mesa with the Xen levels remained in Early Access for a few weeks, but it seems they were well-received, because the complete Black Mesa version 1.0 is now available.

　　To celebrate the 1.0 launch, Crowbar Collective have released a new Black Mesa trailer, which provides a peek at a wide array of iconic locations and moments. The game looks new and retro all at once, and is definitely a must-play before Half-Life: Alyx comes out later this month. Check out the trailer, below.

　　If I told you, say, six months ago, that we’d be basically be getting two new Half-Life games in 2020, would you believe it? I wouldn’t have bought it myself. Somehow not sure what Half-Life/Black Mesa is all about? Here’s the official description:
