Procedural interiors
Corridors, halls and sublevels generated from proportion rules. No two descents share a floor plan.
01 A Vitruviac Games world
Paralux
Closed Playtest
Co-op · parties of 8
Browser · desktop
A cooperative descent into an interior that was never meant to be found. Endless fluorescent rooms, a party of friends, and a light that will not last. Go down together, or do not go down at all.

The web build runs inside this window. Headphones on, lights off, and keep a hand near the exit.

04 The Interior
It goes down further than the plans say
Every descent is assembled from a grammar of rooms. The simulation beneath it never stops.
Cooperative descent
Parties of up to 8. Proximity voice that falls off with distance and through walls.
Something else is here
Threats are simulated, not scripted. They hunt by sound and light, and they remember where you were.
Persistent servers
Official servers keep the interior running between sessions. Doors stay open. Lights stay broken.
05 How to join
Three steps down
Everything runs in the browser. No installer, no launcher, nothing to update.
01
Pick a server
Choose a region above. We preselect the most welcoming one; full servers queue you, and servers in maintenance will not take anyone until the lights come back.
02
Press Play
Play here opens the game on this page with that server chosen. Full window gives it the whole screen. Allow the mouse capture when the browser asks.
03
Gather your party
Copy a server's invite link and send it to friends: it opens the game on the same server. Up to 8 share a descent, voice is proximity-based, and someone should keep a light on.
06 Server rules
Conduct in the interior
Official servers are shared spaces. These rules are enforced by moderators and, where possible, by the simulation itself.
- 01
Respect the party
No harassment, hate speech or threats, in voice or text. The interior is hostile enough.
- 02
No cheats or exploits
Modified clients, macros and exploit abuse earn a permanent ban across all official servers.
- 03
Do not sabotage persistence
Trapping players, destroying shared lights or blocking routes on purpose is griefing, not play.
- 04
Keep voice honest
No soundboards, no impersonating staff, no streaming other players without consent.
- 05
Report, do not retaliate
Use
/reportin game or the Discord channel. Moderators review logs on every official server. - 06
Playtest confidentiality
Closed builds are under NDA unless a transmission says otherwise. Ask before you publish footage.

09 Questions
Do I need to install anything?
No. Paralux runs in a current desktop browser. Press Play, allow the mouse capture when asked, and you are in. Bookmark a server's invite link to return to it directly.
How do I get into the playtest?
Join the Discord and request access in the playtest channel. Invites go out in waves; servers are expanded as the player count grows.
Can I host my own server?
Community hosting is planned after the playtest. Official servers are the only persistent servers for now, so progress is shared and moderated.
What does “persistent” mean here?
The interior keeps simulating when you log off. Doors, lights, resources and whatever you woke up remain as you left them, until another party changes them.
Is there a solo mode?
You can descend alone on any official server, but the interior does not scale its threats down for one person. We recommend at least a pair.
Does it run on phones?
Not yet. The interior wants a keyboard, a mouse and a desktop GPU. Mobile is on the list after the playtest.
