Editorial overview
What it is
Heavily inspired by Anomidae's INTERLOPER webseries, Sourcevoid Online is a massively online multiplayer fan game where you literally fall onto contemporary and forgotten community maps created for Valve’s original line-up of Source Engine titles.
Powered by a custom, remarkably accurate Source Engine asset importer developed for Godot Engine; the game allows you to explore countless maps from Half-Life 2, Counter-Strike: Source, Team Fortress 2, Garry's Mod and other games.
You can play alone or gather with your friends by inputting the same spawn seed on the main menu. Featuring proximity text and voice chats, if lucky enough you might randomly come across and interact with other players exploring the vast void... but be wary: the entities native to this environment do not want you to be here. Can you make it to the door?
