ASPIS Demo Gameplay Breakdown: Portals, the Talking Cat, and the Cycle

What the ASPIS Demo Puts You Inside

The ASPIS demo asks an uncomfortable question: how far would you go to see someone you lost? Dream Wire Games' first-person horror game drops you into a Soviet cybernetics institute where a machine built to simulate reality starts opening doors to places nobody designed. Watch even ten minutes of ASPIS demo gameplay and the appeal is obvious — it is quiet, grimy, and deeply personal long before it gets frightening.

That personal hook is why the demo matters. This breakdown covers what the demo actually contains: the portal loop built on Energy X spheres, the talking Cat, the research reports you find on terminals, and the rough edges players have reported. Everything below comes from the official ASPIS Steam page and from creator-captured ASPIS demo gameplay, with community claims clearly labeled.

The prologue sets the stakes

The demo opens on a phone call dated April 26, 1986, in the June 8, 2025 demo capture and the September 10, 2025 capture. Andrey's wife Anna is staying with relatives near Chernobyl with their daughter Liza, and the line cuts out mid-sentence as something explodes in the background. What follows is grief turned into a game mechanic: an apartment full of paintings, a man who says he cannot eat or sleep, and a colleague calling with an offer — a system meant to simulate not just images but "life, consciousness, memory, time."

Steam's own summary frames the experiment itself in 1987 USSR, with six volunteers hooked up and none of them waking a year later. The demo's April 1986 prologue is where Andrey's reason for volunteering comes from.

Inside the Institute of Cybernetics

Once you are in the building, the pacing is deliberately bureaucratic. You hunt for a magnetic key in office 205, read research notes about Energy X, ride an elevator to the fifth floor, and follow announcements about employees gathering in the presentation hall. Both creator playthroughs referenced here make the same point repeatedly: almost nothing is explained, and the building does the storytelling.

How the Portal Chain Works

The middle stretch of the demo is a puzzle loop, and it is stricter than it first looks. A character named Kamarov explains the rules: this model of portal can only throw you one island forward or back. Rush to the farthest island and, in his words, they will collect you piece by piece from the lower layer. You are building a chain, one island at a time, choosing direction at a nearby terminal.

Mechanically, a run goes like this:

• Find the sphere. Terminals report "the sphere is missing," so you recover an X sphere from storage.
• Load the converter. The sphere sits in the center of an ether converter, and the dialogue warns against bare-hand contact.
• Charge and step back. You start the sequence, keep your distance while the phase converter is active, and wait for the portal to open.
• Pick your direction. A mistake sends you back where you came from.

The handheld device tying this together is the PEP-01. Steam describes it as a tool for capturing, transferring, and stabilizing Energy X — powering machinery, changing the state of mechanisms, and opening what the store page calls astral windows between layers of reality. In practice, that means objects visible in one version of the world can be reached in another.

The Cat, the Cycle, and the Written Reports

Most ASPIS demo gameplay coverage lingers on the Cat, and for good reason. He introduces himself as the "learned cat," talks about time as river water that meanders and drowns in itself, and hands over a toy that lets Andrey "touch the light without getting burned." Fragments of other lives go into the machine, and the path opens. Steam's description confirms the character's role: a Cat who knows ancient pathways and understands far more than he is willing to share.

The documents do the rest of the work. In the July 6, 2025 capture, Report No. 12, dated May 17, 1988, records a test where every participant began hallucinating within about 32 minutes — and each of them heard a deceased relative. One researcher's grandmother called him by name; another heard a child who had died three years earlier. The working hypothesis is that Energy X is not an abstract flow but concentrated memory, will, or residual consciousness.

Then comes the conversation that reframes everything. A figure greets Andrey as a repeat visitor and explains that every step, every choice, is "a shadow of the last cycle." He insists ASPIS is not a simulation at all but a bridge, and that the cycles are a safety lock rather than a glitch. His offer: dive into ASPIS, start a simulation inside the simulation, and force the system to throw Andrey out of this layer of reality.

Horror, Sound, and the Demo's Rough Edges

The demo's scares are built on audio and architecture rather than spectacle. Creators react to scraping noises, breathing walls, blood on the floor of a warehouse, and the long hallways that signal an ambush. One commentary run ends with the player admitting they did not expect the demo to have "such a feel behind it" — and then getting hit by a jump scare anyway. The atmosphere is the strongest argument for playing it yourself.

Puzzle and stealth sections interrupt that atmosphere more often than you might expect: a disinfection chamber, a fire in the warehouse that requires an extinguisher, and a life-support calibration screen where you adjust body temperature, nutrients, and brain activity before a dive. The section is tense, but it also slows the momentum.

Community-reported demo issues

Player experience has been mixed on the technical side. A Steam discussion thread posted June 5, 2025 shared demo footage with feedback for the developer, and a commenter replied that a puzzle visible at the 50:55 mark never appeared for them. Related threads in the same hub ask how to put out the fire and report that the volunteer episode would not trigger in the demo.

If you hit one of these, the practical workaround is to reload an earlier save. The demo autosaves at terminals, and both playthroughs show saves scattered across floors, so progress loss is usually limited.

What the Full Game Adds After the Demo

The demo ends with a thank-you screen and an unfinished story, so it helps to know what ships afterward. As of October 22, 2026, the Steam store page listed a release date of October 23, 2026, with Dream Wire Games credited as both developer and publisher. The same page displayed no user reviews at that time.

Other details confirmed on the store page as of that date:

• Awards: IGROPROM Online 2026 — first place in the IGROPROM Choice category and Best Solo Developer.
• Structure: a single final choice that determines Andrey's fate and leads to one of two endings.
• Cast: other volunteers, the Institute Director, the Cat, and the Devil, none of whom gives Andrey the whole picture.
• Languages: English and Russian full audio, with French, Ukrainian, and Japanese subtitles.
• Features: single-player, Steam Achievements, Steam Cloud, Family Sharing, and Xbox controller support.
• Disclosure: the developer states that AI tools were used for select music tracks, voice-over lines, and visual assets, while the world, mechanics, and scene direction were made by hand.

Steam's mature-content notice also flags violence, blood, psychological horror, sudden frightening images, and sharp flashes of light — worth reading before you start if flicker sensitivity is a concern.

Tips for your first run

• Read the terminals. Codes for office doors and safe combinations come from notes, not from glowing markers.
• Keep doors open behind you. Both playthroughs do this deliberately, and it makes backtracking far less punishing.
• Grab the flashlight early and get comfortable with the hold-to-light input; several sections are near-black without it.
• Adjust life-support parameters before every dive. The in-game report warns that bad settings caused a fatal overheating in a previous test.
• Save at terminals whenever you see one, especially before portal jumps.

FAQ

Does the ASPIS demo gameplay cover the whole story? No. It ends with a "thanks for playing the demo version" message right as the plot opens up. The two endings and the final choice are part of the full release.

How long is a demo playthrough? It varies by how much you read and explore. One community comment references the 50:55 mark of a demo playthrough, so a thorough run can easily stretch past 50 minutes.

Is there combat in the demo? The demo leans on exploration, portals, and scripted scares. Steam describes pistol and melee combat for the full game, with ammunition found in the world.

Is ASPIS out now? As of October 22, 2026, Steam listed the release as October 23, 2026. Check the store page for the live status before you buy.
