Steam just kicked off the Carnival of Chaos, a limited-time event running from July 24th to August 4th, and it’s looking packed with surprises. Hosted by publisher Neon Doctrine, the event brings together horror, action, strategy, and a lot of strange vibes across a curated lineup of upcoming indie titles.
You’ll find exclusive demos, fresh game reveals, and early peeks at what’s coming next from Neon Doctrine’s catalog—all tied together in one big digital carnival.

What is This Event?
The Carnival of Chaos isn’t about one game, it’s a themed celebration. Steam’s homepage gets decked out, and visitors can dive into a collection of unreleased demos, trailers, and sneak peeks. Whether you’re into roguelikes, horror, or something a bit more experimental, there’s a little of everything here.
Neon Doctrine is showing off five new demos, each highlighting different corners of their publishing lineup. Plus, some long-awaited reveals and release date announcements are going live during the event window.
If you like discovering weird, intense, or genre-blending games before everyone else does, this is your window to try them early.
