As the many hapless scientists now wearing wee aliens as hats (and Valve Software themselves) could tell you, one need be careful with Half-Life’s alien dimension of Xen. That’s why the gang behind sanctioned remake Black Mesa gang have taken their time remaking those much-reviled end-game levels, initially releasing the game without any Xen then getting back to work on it. They’ve been gradually expanding Xen in a beta branch, and now they invite us to that weird meaty factory processing (cloning? packaging?) aliens. The unexpected concept made it my favourite part of Xen, so I’m glad to see them go for it.
It feels like only yesterday that Half-Life remake Black Mesa was a joke. The highest-profile vaporware of the Source modding community. That thing had been milling around since 2005. Nobody thought it would ever actually come out. I remember feeling properly shook when eventually did in 2012, seven years later.
Except, it wasn’t exactly done. Crowbar Collective have been trying to figure out Xen, Half-Life’s notorious last chapter, for almost as long as the Earth bits were in development. With today’s Gonarch chapter entering public beta, it got a little bit closer to completion.
Black Mesa's ambitious expansion to Half-Life has reached the last stretch. After a technical beta in June, which tested a few maps, Black Mesa: Xen's first two chapters are now available in the public beta branch. Xen and Gonarch's Layer contain nine maps, so it's triple the size.
The other chapters will be added to the branch later, letting you test all 18 of the expansion's maps. Before you dive in, you can check out the known issues here. Developer Crowbar Collective says things will get quieter on the update front, but only because the team the expansion ready for launch.
Xen has grown over the years from a rework of the disappointing Half-Life level to a full campaign with lots of different environments and improvements. It was originally slated for a 2017 launch, but it's changed quite a bit from the original plans.
