PSYCHO DEAD is bringing its latest demo build to Steam Next Fest: October 2026. Moon Catalyst announced that Patch 4.0 will be available to try during the event running from October 19 at 10:00 AM PT through October 26 at 10:00 AM PT.
The game already has a public Steam demo, so the latest announcement centers on the updated 4.0 build rather than the first release of the demo itself. The full game remains listed for Q4 2026, with development now moving through its final polishing phase.

Demo Patch 4.0, Steam, and Gameplay

Patch 4.0 Is the Steam Next Fest Build
Moon Catalyst specifically directs players toward Patch 4.0 during Steam Next Fest. Valve's week-long event is built around playable demos for upcoming Steam releases.
This is not the first public demo for PSYCHO DEAD. The demo has already been available on Steam, with Patch 4.0 serving as the newly promoted iteration for the October festival.
Elixia Survives With Psychic Powers
PSYCHO DEAD stars Elixia, a mysterious girl trapped inside a secret laboratory filled with the results of horrific experiments.
Combat is not limited to conventional weapons. Psychokinesis lets players manipulate nearby objects, while Shock Shot, Crush, and Barrier provide offensive and defensive options during exploration.
Survival Horror Built Around Combat or Evasion
Moon Catalyst combines limited resources, backtracking, puzzles, and enclosed exploration with a more dynamic combat system.
Players can fight or avoid certain threats, while persistent stalkers with distinct abilities are designed to keep pressure on Elixia throughout the laboratory.
Full Game Is Now Playable From Start to Finish
In its October 7 development update, Moon Catalyst announced that PSYCHO DEAD had surpassed 50,000 Steam wishlists.
The developer also said the full game could now be played from beginning to end and had entered polishing. Steam continues to list Q4 2026, although a final release date has not been announced.
Why This Matters
1) The demo continues to evolve close to launch
Patch 4.0 shows Moon Catalyst is still iterating on the playable demo while the full game approaches completion.
2) Psychic abilities give the horror its own combat identity
Psychokinesis turns surrounding objects into tools, while other powers offer alternatives to ordinary firearms.
3) Next Fest arrives during the polishing phase
Players will be able to sample the latest build while the full release remains scheduled for Q4 2026.
