Seems like you're wanting to create a mod! And why shouldn't you? After all, there are some great examples out there. DarkStar had far too many Headcrabs, or I need new weapons for HL, but I don't want to alter any code, models or skins. I know you've been thinking in the past, things like: Blue Shift's too short. Putting Your Mod Into the Custom Game Menu You still wouldn’t have it today, even if we’d gone that route and put everything into it.This tutorial is for the WON version of Half-Life. The short version is “Xen would still be extremely huge amounts of work, even if we were aiming for just a straight 1:1 remake. If you want to know why Black Mesa multiplayer was prioritised over finishing the Xen levels, there’s a pretty lengthy explanation from one of the team over here. Those are part of the Early Access development plan, which includes: “The conclusion of the single player campaign, with the addition of the Xen chapters Final polish on the Earth-based chapters of the single player campaign More multiplayer maps and more multiplayer gameplay modes.” “Does this version have the Xen bits?” The answer is no. Multiplayer deathmatch and Team deathmatch (in the Half-Life 1 style) are available across “6 completely re-imagined Half-Life 1 maps on the Source Engine.” That new engine is not Source 2, but a hybrid of several other Source branches and features. It also launches with a few differences from the free version, namely: “upgrades, bug fixes, a multiplayer addon, and a port to a new engine.” So, the $20 USD Early Access version of Black Mesa will be the one which receives updates and improvements in future.

This was effectively confirmed by a post back in December, which says “at this time there are no plans to upgrade or add to the “mod” release.”

That also means the freebie version won’t get any more updates. The link is no longer available on the official Black Mesa site, but the Crowbar Collective have confirmed they are “not going to do anything else with regards to the free version that’s already available.” It’s still available here at Moddb, for example. Firstly, the free “mod” version of Black Mesa is still available.

There some obvious questions that accompany this news, so let’s try to cover all of those. The hubbub surrounding enigmatic Black Mesa teaser trailers can now subside, as the former mod project goes “retail” with a Steam Early Access release.
