This is the first in a series of six videos that detail every single bit of information found through datamines related to HLX/HL3. The information you will find within this series is the result of nearly six years of dedicated research and collaboration by many members of the community.
This first episode details all the jargon you'll need to understand moving forward, a timeline of explicit HLX events between 2019-2025, and all the misunderstandings surrounding the project, and how we know those specific points are debunked.
The next episodes will dive into other topics, being;
The Gameplay Mechanics/Vehicles
The Spoilers/NPC/Enemies/Locations
The AI/NPC Behavior
The Engine (Source 2 2026)
From Valve's Own Mouth (Everything Valve has said on the topic for the last six years)
I want to think all the community members who worked on the Miro Board, and especially Rowleto for writing major chunks of this series script, and helping me understand the more technical aspects.
Also, thank you to dirtkiller and Kayla for looking over and improving that script to ensure everything we discuss is accurate.
Lastly I want to thank LVJohnFreeman for the amazing thumbnail work for the last few videos. That dude is an artist.
