Those who carefully watch our space probably noticed that besides our Guard Duty summer update, we have also released several dev.blogs of which the last of which was released today. And what it was all about?

A Byte of Insight - Programming Dev Blog

This dev.blogs uncovers something we haven´t been talking about much in our updates. Tmast, one of our programmers wrote down his first dev.blog about what he has been cooking for you to enhence your experience by adding some nice features to the Source engine. Get yourself familiar with just a fragments of some visual improvements for Operation Black Mesa and Guard Duty.


What's a Brush? - Chris's Prop Devblog (part 2)

Our artists never sleep and Chris is working round the clock to produce some top-tier models and textures. As usual, he pushes the Source Engine beyond its limits, creating crucial assets for level designers to create the stunning and realistic environments you will experience.


EGGs Prop Party

Our senior developer, Brandon, seems to be damn party boy. This endless party is something you don´t want to miss out. Throughout this summer, he has released several updates showcasing more of his artistic talent. And this party is not over yet.


Stranger Beings - AI Dev Blog

Quite sometime ago, we released a dev.blog video showcasing our AI. Many of you was very curious what´s the current state of our AI system. Chris (Tmast) was working hard on improving and fixing our AI and he wants to show you that we take this bussiness seriously. For us, AI is very important for delivering you breathtaking and realistic experience. Our AI is not about simple routines, it´s about creating believeable and lifelike characters, each with it´s own unique characteristics.


Thank you for your support throught the years and we hope you stick with us for the future. This is our last contribution for this summer seasson, but never fear!

Will Barney have a voice actor? I'm asking because Barney appears to talk in Blue Shift. For example, when Rosenberg asks him how Barney knows his name, there is a slight pause, then Rosenberg confirms the name of the scientist who told it to Calhoun ("Oh, I see. Poor Harold."). Idk, I think I'd be cool if Barney had a voice in this remake.

Also I don't really know if this has been answered but... will Barney's melee weapon be a crowbar just like Gordon's? Or will you change it to give Barney his own iconic weapon?

Currently the player has no voice and chances are we will keep it that way.
At the moment the crowbar is a weapon you get early on just like in the original, although there is a slight chance we might make the flashlight into a melee weapon as well. But don't count on it as a sure thing ;)

I have some suggestions about the gameplay of your project.
In addition to Half-Life, I'm a fan of the game System Shock 2 and I take the ideas from it.
In Half-Life 2, the mechanics of the game did not change much from the first build, and I find it rather sad, even in Doom 3, the player received an electronic journal and could read other people's letters containing valuable information.
1. It is necessary to add an electronic journal, the ability to read electronic and paper media (disks, flash drives, letters). This will help to reveal the world of the Black Mesa better.
2.Development of skills. At least partially.
3.To open the closed door you need to solve the intellectual task. Or hack it as in System Shock 2 or solve a puzzle as in Dino Crisis. Also this should be not only with the opening of doors, for example the repair of an energy generator, etc.
I would like more advanced gameplay than a simple shooter

Although personally I LOVE games that have journals to read, etc, we are most likely not going to include those.

And as much as I love games with skill trees, we are definitely not going to include a skill tree of any kind.

It's just not HL at that point anyways; and I see little point in shoving game elements into our game just because they work well in other games.

I'm working on some new gameplay/puzzle mechanics for accessing locked doors, etc, that will be exclusive to Guard Duty (definitely nothing like system shock or any of that though). Which may or may not make it into the final game depending how well they work/feel.

If you are worried that the innovations in the gameplay scare away the fans of Half Life, because it is not part of the canon, it will not save you from criticism, still there will be those who find your project uncanonical.
I hope you do something with the gameplay, 2017 is not the best time for simple shooters.

We are not worried about that at all. We simply do not want to add different mechanics like that. If people don't want to play, then they are free to not do so.
We are trying to remake a HL game, not a bioshock or system shock game.

Edit: I'd argue that the lack of simple shooters in 2017 is actually one of the reasons I like our project. Everything now adays is skill trees, microtransactions, regenerating health, and wall running.

Doom 3 is remake of Doom 1, but there was a electronic journal, code locks. In the great mod Half-Life Invasion there was chapter when a player needs to explore computers and find the necessary information, hide from enemies.
Well, do what you wanna do. I just said my opinion. I will play in your mod in any way, i like Blue Shift.

You have made so much, you work already six or seven years, hope you will finish this soon. Last screens looks pretty good. This must be something cool.
