A Garry's Mod roleplay project
Text-based horror & thriller one-shots, staged like films. Built on Source. Pushed far past where it was meant to go.
aletheia is an ongoing, mainly horror and thriller themed text-based roleplay server project for Garry's Mod. Our goal is to offer something new by pushing Source Engine to its absolute limits — making it look far more modern than it has any right to.
Every session is built around an immersive, cinematic atmosphere, staged with tools we've spent the past few years developing in-house.
The core of the project is sessions — self-contained one-shots that run on a schedule. You don't need a hundred hours of backstory to step in. You need a character, a flashlight, and the nerve to keep it on.
Sessions run on announced schedules, so every player arrives at the same moment the story begins.
Self-containedEach one-shot has its own setting and theme — an abandoned homestead, a sealed basement, a cemetery at first light. No two sessions look or feel alike.
Never the same twiceSome stories refuse to stay buried. Scenarios that warrant it return as sequels — same world, deeper story, and consequences that carry over.
Continuity optionalThe next one-shot that will be ran. Date, seats, and an image from the event. You will learn more once you are inside of the event.

Three years of in-house tooling goes into every frame. We treat Garry's Mod less like a sandbox and more like a film set.
Years of running this project doesn't happen by itself. Below is the team that is involved in the development and creative process.
No. Sessions are self-contained and text-based — if you can describe what your character does and stay in the moment, you're qualified. The atmosphere does most of the heavy lifting, you just need to maintain your place within it.
They stay dead for that story. Since each one-shot is its own scenario, a death is an ending, not a punishment. You'll be back in the next session with someone new. Some of our best moments came from characters who didn't make it out.
No. This is text-first, slow-burn horror roleplay. Mechanical skill matters far less than your willingness to write, react, and let a scene breathe. Whilst the combat is shoot-to-kill, it has been fine tuned to remain immersive and balanced.
Sessions are announced ahead of time with the date and a teaser of the setting. Seats are limited to keep events intimate, so sign-ups open on our community hub — watch the "next transmission" briefing above and join the Discord to be notified.
Horror and thriller themes: dread, gore, the occasional thing in the dark that does not stop walking. Content boundaries and tone are set per scenario and communicated before each session — read the briefing, and if a theme isn't for you, sit that one out.
Fill out the intake form. We'll take it from there.
