Post news RSS Progress Update 2: MOTY Edition

A brand new update to ask people to vote Guard Duty on MOTY.

Posted by on

Hi everyone, Vasiavasiavasia95 here. The 2021 is coming to an end so we figured it's a good time to bring you all a new progress update.

Since the previous article we've been focusing on refining our current work, fleshing out new designs, ideas and improving the gameplay to provide a good experience for the player. Unlike the previous update, this one is going to be more programming oriented. At the time of the last update, our code base needed a severe cleanup so we decided to focus most of our power on doing so. But don't worry, this update isn't going to be a nerdy talk describing what we fixed and what not. We got a bunch of awesome features implemented that we just can't wait to share with you.

Without further ado, let me show you what we've been working on.


Let's start with probably the coolest feature I have implemented so far - new game chapter selection system.

That's right, I've managed to implement a FULLY WORKING custom new game menu option in Goldsrc. It's directly inspired by what Valve did for Source and functions very similarly to it. I found this to be a pretty neat feature to implement since no one had ever done this before and we find allowing players to start from any chapter they want to be a very nice game design idea.

Of course, the implementation isn't limited by a new menu dialog, we are currently working on updating all of our maps to make sure everything works correctly because original maps were obviously not made with such feature in mind.


The visual effects in the mod also got an overhaul. While most of the changes a simple tweaks and fixes. There are a few new additions I want to showcase.

- I programmed a new version of the beta particles blood effect. Using reverse engineered Alpha and Day One code as a reference I made it look pretty accurate to what can be seen on the pre-release footage

- The sparkle effect now has an alternative option - Alpha's particle based sparks

- The infamous beta shadows were reimplement back as well. My reimplementation don't crash on post-steampipe builds of Goldsrc so you can enjoy them without having to use an outdated version of the engine.


- Now, this isn't exactly a visual effect but the even more infamous model interpolation bug ( models blinking on moving trains ) had been fixed as well. Now you will be able to experience the elevator crash sequence just like when BS was first released.

Well, that's all we wanted to showcase from our programming side. However it wouldn't be a proper update without at least some mapping media. So let's jump straight to it!
( Keep in mind this is all WIP and is still a subject to change ).

How did you fix the model flickering bug on the trains? I've been looking for how to fix that for months :0

Is this a mix of Half-Life 1 Alpha and Blue Shift Alpha?
