Hi everyone!

With everything that's been happening recently, I have a feeling we might be getting some news about what many of us have been waiting for. Because of that, I decided to put together a complete timeline of the Half-Life universe, summarizing both the established lore and some of the gaps in the story.

Most of this timeline is based directly on the games—especially the new information introduced in **Half-Life: Alyx**. Where Valve has left unanswered questions, I've included a few of my own interpretations and theories. To keep things clear, anything that goes beyond confirmed lore is presented as my personal speculation.

Since English isn't my native language, I also used AI to help improve the wording and readability of the text.

I'd also like to give special thanks to **SquaredEyeS** (@SQUAREDEYESgaming) and **Blackline** (@blacklin3). Their videos and theories inspired some of my own ideas, and I wanted to properly credit them for that.

I hope you enjoy reading it! Whether you agree or disagree with my interpretations, I'd love to hear your thoughts and discuss them with fellow Half-Life fans.

Thanks for reading!    [https://halflife-timeline.web.app/](https://halflife-timeline.web.app/)

  
Feel free to point out any mistakes or lore inconsistencies I may have missed. I'm always happy to update and improve the timeline.
