ASPIS Demo Preview: Soviet Horror, Talking Cats, and a Broken Reality

Why the ASPIS Demo Matters More Than Most Horror Demos

A phone rings in a quiet apartment, and by the end of the call something has exploded in the distance. That is how the ASPIS demo opens, and it sets the tone for everything that follows. This is a story-driven first-person horror game from Dream Wire Games, set in a late-1980s Soviet Union where an experimental machine was built to predict historical events and instead opened doors nobody planned for.

If you are weighing a wishlist add before the planned October 23, 2026 release, the ASPIS demo is the cheapest possible test of whether this particular brand of dread works on you. It is short, it is loud in all the wrong places, and it leaves a lot of questions hanging on purpose.

Here is what the playable build actually contains, how its portal puzzles work, where it gets genuinely frightening, and which community-reported bugs you may run into.

What the ASPIS Demo Actually Is

The setup comes straight from the store description: six volunteers are connected to ASPIS, a system designed to forecast historical events, and one year later none of them has woken up. One of those volunteers is Andrey, an engineer who signed on for a single selfish reason — the chance to see his deceased wife, Anna, and his daughter, Liza again.

The ASPIS demo covers the opening stretch of that story. You start in a domestic space, move into the Institute of Cybernetics, and gradually push past the edges of what the machine was supposed to simulate. According to the Steam page, that journey eventually leads "toward distorted versions of recognizable places, ancient structures, and worlds that existed long before ASPIS was ever launched" (ASPIS on Steam).

Because the demo is a vertical slice rather than a beta of the whole campaign, it ends with a clear message thanking players for trying the demo version and teasing that the story is only beginning. Nothing about the ending sequence carries over into the two-ending structure of the full release.

Inside the ASPIS Demo: The Phone Call, the Safe, and the Cat

In the recorded demo playthrough published September 10, 2025 and the playthrough published June 8, 2025, the opening takes place on April 26, 1986. Andrey's family is visiting relatives near Chernobyl, the call is warm and ordinary, and then the line catches an explosion — player experience that reframes the entire scene once you realize what that date means.

From there the demo shifts into the institute, and this is where it slows down in a good way:

• Documents and terminals. Research notes explain that X energy has been partially harnessed but never fully understood. OGAS-style terminals hold mail, announcements, and file system fragments, most of them empty or disconnected.
• Physical puzzles. A magnetic key tied to office 205, a safe code stitched together from dates, and a locked lab door that requires you to actually read the notes you walk past.
• The talking Cat. A cat that knows the ancient pathways introduces the portal system and speaks like it has met Andrey more times than he remembers. It is easily the strangest and best-written element in the demo.

The building itself does the heaviest lifting. Presentation hall announcements play to rooms that are empty, the fifth floor has a view nobody is around to enjoy, and a floating chair sits in an office like someone just left it.

How the ASPIS Demo Plays: Energy X, Spheres, and Island Portals

The demo's core loop is built around the PEP-01, a handheld device for transmitting and stabilizing energy flows, and around X spheres that power the ether converter. You place a sphere in the converter, pick a direction at the nearby terminal, and the system charges a teleportation window.

A few rules from the demo are worth knowing before you try it yourself:

1. You cannot skip ahead. Each portal throws you exactly one "island" forward or back. Attempting to leap to the farthest point gets you pulled out of the lower layer piece by piece, according to the in-game explanation.
2. A wrong direction sends you back. The terminal is a commitment, not a preview.
3. Keep your distance during the charge. The phase converter explicitly warns you to stand back while it is active, and spheres can come out of the process damaged.
4. Use the objective log. The tab key opens the current checklist, which matters because the demo gives you very little direction otherwise.

Later, the demo shifts into a calibration sequence with a brain-activity minigame and a disinfection chamber before a dive. It is a deliberately clinical stretch that makes the next section hit harder.

Where the ASPIS Demo Gets Genuinely Scary

The horror in this build is mostly audio-first. Metal scrapes on concrete, cardboard friction, something breathing where nothing should be, and long corridors that telegraph a grab from behind. Then it adds a tall, thin figure in the warehouse that appears, disappears, and never quite commits to attacking.

Community playthroughs describe instant chills at scratch marks on a wall, blood on the floor near a stairwell, and a diary entry warning readers not to trust their eyes or ears. A fire-extinguisher sequence on the lower floors interrupts the exploration with an emergency broadcast and a hard time pressure, and the emergency power section forces you down to a technical floor where the lighting turns red.

It is not a combat demo. The recorded playthrough never fires a shot, and the full game's Makarov pistol and melee combat are documented on the store page rather than showcased in this build.

What the Full Game Adds Beyond the ASPIS Demo

The ASPIS demo is a corridor; the full release is described as a much wider set of worlds.

• Two endings decided by a single final choice that determines Andrey's fate.
• Combat with a Makarov pistol and melee, with ammunition and resources scavenged along the way.
• More characters, including other volunteers, the Institute Director, and the Devil, none of whom explain the whole picture.
• Steam features: single-player, achievements, Steam Cloud, and Family Sharing.
• Russian and English full audio, with French, Ukrainian, and Japanese subtitles.

Dream Wire Games has also disclosed that AI tools were used for select music tracks, voice-over lines, and visual assets, while the world, environments, mechanics, and scene direction were built by the developer. The game took first place in the IGROPROM Choice category and won Best Solo Developer at IGROPROM Online 2026.

On that same capture date, the store page showed the game as not yet available and had not yet published user reviews. That status is a frozen snapshot, not a live reading — check the store page for anything that changes after launch.

System Requirements and Community Reports

Before you download anything, the documented minimum is Windows 10 with a Ryzen 5 2600 or i5-10400F, 16 GB of RAM, a GTX 1660 or RX 5500 XT with 4 GB of VRAM, DirectX 12, and 20 GB of storage. The recommended tier bumps to 32 GB of RAM and an RTX 2060 or RX 6600.

Community reports from the demo period are worth reading with a grain of salt, since they describe a build that has since been iterated on:

• A June 5, 2025 Steam forum thread paired a demo playthrough video with feedback for the developers; one commenter reported a portal puzzle that refused to appear around the 50-minute mark.
• Separate threads asked how to put out the warehouse fire and reported that a volunteer episode would not trigger in the demo.
• Other players requested ultrawide support and a mouse-invert option.

Treat all of that as player experience rather than confirmed behavior in the shipping build. If you hit a soft block in the ASPIS demo, the Steam discussions are the fastest place to check whether someone else saw it too.

Should You Play the ASPIS Demo Before Launch?

Yes, if atmosphere matters more to you than combat. The ASPIS demo sells a mood — analog terminals, bad lighting, a cat that knows too much — and it is honest about being a fragment. Players who need a gun in hand within the first ten minutes will bounce off it.

Yes again if you are the type who reads every note. The demo hides most of its story in documents, terminal mail, and offhand lines from characters who clearly know more than Andrey does, and skipping them leaves you with a walking simulator in a broken office.

Skip it if jump scares wear you down. There are several, they are loud, and at least one lands with no warning at all.

FAQ

Is the ASPIS demo still available to play? Creator playthroughs and Steam forum feedback from June 2025 confirm a demo build existed, but the Steam listing captured on October 22, 2026 promotes the full game and does not advertise a demo download. Check the store page directly for availability.

Does the ASPIS demo cover the whole story? No. It ends before the finale, with a message thanking players for trying the demo version. The full game closes on a single choice leading to one of two endings.

What is the ASPIS release date? The Steam page lists a planned release of October 23, 2026, and as of the October 22, 2026 capture it showed the game as not yet available.

Do I need to play the ASPIS demo to understand the full game? Nothing suggests it is required. The demo is an early slice of Andrey's time inside the system, and the store description covers the premise — six volunteers, one year, no one awake — without it.
