What the developers have to say:

Why Early Access?

“Early access gave us new tools and resources to better complete the game. We plan to fully utilize these resources even now that Xen is out.”

Approximately how long will this game be in Early Access?

“The full game, including the Xen levels, is available now!

We plan on doing a complete pass on the whole game for bugs and polish, then we will release out of Early Access. Targeting early 2020.

Soon (TM)”

How is the full version planned to differ from the Early Access version?

“Final polish on the Earth-based chapters and additional polish passes on Xen.

Fixes and refinements to multiplayer.

Better implementation of the workshop.”

What is the current state of the Early Access version?

“Over 10-15 hours of single player campaign. Multiplayer deathmatch and team deathmatch with 8 completely re-imagined Half-Life 1 maps on the Source Engine.”

Will the game be priced differently during and after Early Access?

“Black Mesa will be $19.99 USD during the Early Access phase. This price will NOT change after we move out of Early Access.”

How are you planning on involving the Community in your development process?

“We have been using betas, the Steam forums, and Discord to compile feedback and find bugs. This has worked better than we could have imagined. We will continue to leverage that community to improve the game.”

Reviews

“This is Half-Life updated just enough to make it palatable for contemporary tastes, but not so much as to deviate from the original vision.”
YES – Kotaku

“Black Mesa Source winds up being exactly what it always promised to be – a modernised, faithful recreation of a deservedly landmark first-person shooter.”
Rock Paper Shotgun

“It's a brilliant tribute to one of the greatest videogames ever made, and it's also a good game in its own right.”
8/10 – Destructoid
