In the depths of the Black Mesa Research Facility, a rumbling noise. It was not loud, yet seemed louder than mere decibels would suggest in the furtive, creaking hush of the facility's underbelly.

There are those who, when the time comes, take control of their own destinies. The right people in the wrong place.

Maurice Andrews was thrown from his feet by the chaos that followed the Resonance Cascade, tearing and deforming the once familiar facility around his unconscious form. Even at this, Andrews, a low-level engineer could not possibly know the full extent of the incident and upon waking he has only one clear objective: Get to the surface.

Even with the support of other survivors met along the way, however, nothing could prepare him for the adventure ahead, the heavy handed presence of the military of the creatures whose existence they were sent to cover up...


The Core is a classic retelling of the events surrounding the Resonance Cascade disaster from a new perspective; that of Engineer Maurice Andrews. Without using bolted-on engine modifications, The Core will provide a grand single-player experience featuring intense action, complex puzzles and believable narrative through all-new locations in Black Mesa with remarkable visual fidelity, pacing and humour.


Any PC capable of running the original Half-Life game will be able to run The Core, however due to the increased resolution for the textures as well as the ambitious scale of some of the areas, slight framerate drops may be noticeable on older or budget systems. We employ advanced optimisation techniques to minimise this, and most players will not exprience any framerate loss.

The Developers

Almost entirely created by just two people, The Core is the endeavour of Andrew Morris & James Archibald, with coding from TWHL's Penguinboy - developer of the Sledge Editor Hammer alternative. They try to be friendly and approachable and will answer any questions or comments left on articles or media. On ModDB, their usernames are Urby & Archie_SnC.

Happy New Year...

News 11 comments

First of all, let me just say on behalf of everyone working on The Core, Happy New Year! Let's hope 2021 is a little better for all of us.

Unfortunately, to start off with at least, I'm afraid we have a little bit of bad news.


The more observant of you (and those who follow me @urby1986 on Twitter) may have noticed that The Core's release date is not as solid as it has been. Yes, I am sorry to say that despite our best efforts, we have had to adjust our release date yet again.

With 2021 kicking off with a new strain of everyone's favourite global pandemic here in the UK, we are once again in lockdown for the foreseeable future. Schools and businesses are closed and so while I continue to work from home, homeschooling takes priority once 5pm rolls around.

As such, I regret to say that the previous release date of 31.03.21 is no longer realistic.

However, we have decided to hold on to '2021' as the target. We are confident that one way or another, within the next 12 months The Core will see the light of day. It might not be as soon as March, but there is good chance that it won't be quite as late as December either.

It's not all doom and gloom.

Development is still powering ahead during the occasional gaps in our busy schedules. We will still be taking leave from work in the coming weeks and now that we find ourselves confined to our homes, that is actually a positive in terms of The Core's development. I myself have a week off after tomorrow, so I will be staying in, working away on this project.

What's more, I am very happy to say that some major improvements have been made to one of the later chapters in the mod, having received a full gameplay overhaul by Archie following tester feedback.

We are also still writing up the plot related dialogue and having recently streamed this internally to a couple of friends, we believe that meeting and engaging with the central cast in The Core will be very entertaining indeed.

We will see you up ahead

In the meantime, keep your eyes peeled and make sure to follow us on Twitter (@sncgames) if you're not already. Also, check our previous article if you want to join our Discord server and discuss things with the devs.

We will aim to keep you up to speed on the development as much as we can, though we have reached the point now where we will likely show limited media. While we continue to wrap things up and work on some of the more eventful scenes, it would be a shame to spoil some of them. We truly hope that some of the things you witness throughout The Core will genuinely surprise you.

So, with that said, thank you once again for your time and your ongoing support. We are still here, working as hard as we can, when we can, to get The Core into your hands.

Happy 2021,

I know you have your own edits to the code for this, but I am wondering what you used as your base. Was it one of the spirit of half life versions, or something else entirely?

If the delay serves the better quality and more polished final release at the end, it's worth the waiting :)

I went through screenshots all the way to 2008 and man, it amazes me how great it looks all the way through. That's some dedication. Well-made half-life mod and very long story, is there a better combo?

People were telling me how long they were waiting for Cyberpunk, I haven't told them how long I have been waiting for The Core.
