Now, before we get to the core of things. I offer sincere apologies to everyone that followed this mod for the past three years. These past years have been hard on me, and i couldn't keep up with both work, school, and my personal life. It was stresful, but i managed through it.

I feel into a deep depression following my percieved lack of success with the mod. I wasn't myself, really. Though i've abandoned Halfquake Rebirth, i've done other things during that time, but i felt empty. I needed to return to my flagship mod. And so, i have returned, carrying both bad, and good news.

Bad News

Straight to the point, i haven't done a lot of work for the past year. I'm really sorry for it.

This mod is my most important piece of work, without it, i wouldn't be here..

Good News

I'm going to ensure the mod is finished, in one way or another.
To pull this off, i will need your support, more on that later.


We will begin by looking at the maps.






That's the maps, in a new presentation style.

Now, you're probably wondering what i've been doing before now.

The anwser is...

Hello from 2021 ✌️😄
Did you know that an unpatched copy of The Orange Box for the PlayStation 3 is a completely unique experience to that of any other version? Half-Life 2 Episode 1 has never been so broken. Want to see what I'm talking about? Check here:

And yes... Half-Life 2 is the most broken experience out if the 3 base games... From swimming APC's to a complete loss of audio due to an airboat crash, there's so much to be experienced. Check out my Half-Life 2 UNPATCHED playlist for more information. Or, stick around for my 240+ episode Half-Life Mods series? Ooorrr, how about a Half-Life 2 Permadeath Run series? All this and more on my YouTube page ✌️😎

No half life 2 episode 1 mods? why are there no episode 1 mods which follow the same story as in episode 1? There are tons of mods that follow episode 2 but why not episode 1? There are only 2 mods but both are however Broken
