An ASPIS full walkthrough is useful because official material names the journey’s locations but not a numbered chapter list. This route follows the Institute of Cybernetics, KGB building, tunnels, and strange layered destinations, while separating confirmed details from unverified solutions.
ASPIS Full Walkthrough Overview and Story Route
ASPIS begins in a reimagined Soviet Union in 1987, where engineer Andrey becomes involved in an experiment involving his deceased wife, Anna, and their daughter, Liza. Official material also identifies six volunteers, an OGAS terminal network, and a device called the PEP-01. These details establish the route better than invented chapter labels do.
The official ASPIS website describes ASPIS as a passage into spaces whose physical rules stop matching our own. The title expands to Autonomous System for Predicting Historical Events, while the official store page establishes the broader premise, available locations, two endings, and central equipment. No official source publishes numbered chapters, episode names, or a complete puzzle-solution index.
| Route element | Confirmed information | What it means for the walkthrough |
|---|---|---|
| Institute of Cybernetics | Central research setting and home of OGAS terminals | Begin with exploration, terminal interactions, and volunteer-related objectives |
| KGB building | Named area with a combination lock | Check every searchable object rather than assuming a published code |
| Tunnels | Connected area where a named prisoner can be found | Explore alternate routes and inspect the environment carefully |
| Warehouse | Officially documented location | Treat it as a route milestone, not an officially numbered stage |
| Red World and red corridor | Layers presented in official gallery captions | Follow portal-related leads and record what each layer changes |
| Lukomorye | Island setting named in official material | Reach the island route and examine its edge-related objectives |
Opening Moves at the Institute
Your route should begin at the Institute of Cybernetics because it anchors the initial research complex and introduces the OGAS system that drives the story. The official description centers Andrey on reconnecting with people from his past, so exploration matters alongside combat and puzzle solving. Talk to available characters, inspect terminals, and gather resources before committing to a harder route.
The Institute also provides the clearest explanation of the PEP-01. This device interacts with Energy X and opens astral windows between layers of reality, making it the bridge between the physical Soviet setting and the later locations. As you inspect terminals and related objects, record prompts that mention the system, the volunteers, or a way onward. Those clues can prevent you from overlooking progression that does not appear as a conventional quest marker.
Keeping the Early Route Safe
The Institute is the right place to establish a careful exploration routine before the route expands into the KGB building, tunnels, and surreal layers. Pick up ammunition and other resources as they appear, because the official game page confirms that useful supplies are distributed through the environment. A resource-first habit reduces backtracking and helps when a guarded path or the Guardian blocks direct progress. For a broader breakdown of systems and preparation, use the ASPIS game guide. That article is especially useful for understanding the equipment-selection interface, flashlight behavior, and other documented features before you attempt the complete ASPIS full game route.
Institute and KGB Building Walkthrough Steps
The most reliable ASPIS full playthrough begins with a location sweep rather than a strict mission checklist. In the Institute of Cybernetics, speak with characters, inspect the OGAS terminals, and search rooms for resources and narrative objects. The objective is to understand what the system wants from Andrey before moving toward the KGB building.
At the KGB building, use the same process with greater attention to combinations and environmental clues. An official achievement confirms that the building contains a combination lock, but neither the achievement list nor the store page publishes a universal code. Do not treat a code from community reports as confirmed until you verify it in your own session.
| Location | What to inspect | Practical objective |
|---|---|---|
| Institute rooms | Terminals, work areas, containers, and documents | Identify references to the experiment, volunteers, and next route |
| OGAS terminals | Every reachable terminal prompt | Record unlocks, altered text, and inaccessible systems |
| KGB building entrance | Lock mechanism and nearby environmental details | Search for clues before attempting combinations |
| KGB interior | Side rooms, resources, and access points | Avoid committing immediately to a single corridor |
| Tunnels connection | Alternate passages and the prisoner route | Follow the confirmed search for Evgeny Kotov |
Reading the KGB Combination Lock
Treat the KGB combination lock as an in-world observation task. Read nearby notes, examine the mechanism, and note anything that suggests numbers, symbols, or a sequence. The official achievement tied to opening it quickly proves that a time-sensitive success condition exists, but it does not establish the code. The achievement wording is also evidence that the game evaluates the action, not a guarantee that every player should rush.
If a community solution appears to work, treat it as a clue rather than an answer. Community reports are useful when they describe where the relevant object can be found, but they can also copy a different difficulty setting or an earlier build. Confirm the mechanism in your own run, and keep a note of the sequence only after seeing the lock accept it.
Using the Achievements as Route Clues
The official achievement list can reveal optional interactions without inventing a mission list. Documented entries refer to a packing machine, the Devil’s cage, a freed prisoner at the island edge, and a drawing inside a portal. Each is a search target, not necessarily a required main-story checkpoint, so sweep each area before moving on.
A separate achievement concerns returning the Keeper’s Seal, while another references a drawing in the right-hand portal. These descriptions reinforce a practical rule: interact with unusual objects and inspect both sides of a portal. If the surrounding area contains a themed object, the game may reward a precise action rather than simply entering the next zone. For more focused coverage of the opening locations, consult the ASPIS all episodes route. It follows the institute and KGB building in more detail, which pairs well with this broader, location-based ASPIS full walkthrough.
Tunnels, Prisoner, and Warehouse Route
After the Institute and KGB building, the confirmed route expands through the tunnels and other industrial spaces. The official achievement “Case Closed” states that Evgeny Kotov can be found in the tunnels. Treat his location as a search objective, but do not assume the achievement fires as soon as you see him; some ASPIS achievements depend on a specific interaction, such as hearing or freeing a character.
The tunnels also reward careful environmental reading because the route eventually connects to the warehouse and the stranger layers beyond them. Listen for character voices, check side passages, and look for environmental prompts before following the most obvious path. Ammunition and other resources may also be found in these areas, so sweep dead ends even when they appear unrelated to the current story thread.
| Checkpoint | Official clue | Suggested action |
|---|---|---|
| Tunnel entrances | Evgeny Kotov is findable in the tunnels | Search alternate branches and listen for dialogue |
| Prisoner encounter | An achievement covers a freed prisoner at the island edge | Speak, inspect, and complete the relevant interaction |
| Packing machine | An achievement references unpacking an empty container | Operate or inspect the machine if encountered |
| Devil’s cage | An achievement references breaking the cage | Examine the cage and available interaction |
| Warehouse | Named as an official location | Search for resources, lore objects, and onward access |
| Island edge | A freed-prisoner achievement points to the edge of the island | Inspect the boundary and nearby objects |
Finding Evgeny Kotov in the Tunnels
Begin the tunnel search away from the main route, because a named character may sit in a side branch or behind an environmental detour. Listen for speech cues, then inspect doors, cages, and alternate passages. If you reach a dead end without a visible character, check whether an interactable object or viewpoint was overlooked rather than immediately retracing every step.
Do not skip nearby collectibles while searching for Kotov. The official store description supports exploration-based resource gathering, and the tunnels provide natural places to collect ammunition before dangerous encounters. The search-and-sweep loop—listen, inspect, gather, then advance—works better here than rushing from one marked object to another.
The Warehouse as a Transition Point
The warehouse is officially named, but the material does not assign it an episode number or disclose a puzzle solution. Treat it as a transition between the grounded Soviet locations and the later layered environments. Examine machinery and storage areas, note any references to Energy X, and look for a transition that connects to the Red World or the red corridor.
The warehouse also serves as a good checkpoint in an ASPIS full game run. Before leaving, confirm that you have checked side rooms, collected visible resources, and recorded any terminal or story dialogue that could explain why the route is moving toward a different layer of reality.
Red World, Red Corridor, and Portal Route
The Red World and red corridor are named in official gallery captions, making them central to the ASPIS full walkthrough. They also mark the point where the story moves beyond ordinary research facilities. The PEP-01 and astral windows explain the transition, while Energy X provides the system linked to those windows.
Because official material does not provide a step-by-step portal chart, record each portal’s surroundings as you travel. Note the color of the corridor, nearby objects, dialogue, and which side of the portal produced a new drawing or interaction. The achievement for a drawing inside the right-hand portal confirms that portal content can hide a distinct object, not merely serve as scenery.
| Layer or portal clue | What it indicates | Route action |
|---|---|---|
| Red World | One of the named alternate locations | Search for resources and objects before leaving |
| Red corridor | A distinct red passage in the official gallery | Follow the connected path and note branching options |
| Astral window | PEP-01 mechanism for crossing layers | Inspect the device or prompt before crossing |
| Right-hand portal | Contains a drawing connected to an achievement | Interact with the correct side after arrival |
| Left-hand portal | Official material does not confirm equivalent content | Inspect it without assuming a matching reward |
| Energy X | A documented interaction source for the PEP-01 | Use related terminals and prompts to advance |
Crossing Astral Windows
An astral window should be treated as both a transition and a checkpoint. Before crossing, note the route that brought you there and search the immediate area for ammunition, documents, and interactive objects. The ASPIS Ogas terminal guide provides focused help with terminal prompts, the red corridor, the Red World, and portal puzzles without replacing the broader route.
After crossing, compare the new area with the one you left. Look for changed lighting, altered object states, different character dialogue, and any repeated terminal. These details can reveal whether the transition moved you sideways through the same reality, into a deeper layer, or back toward a route that still contains unfinished business.
Handling Portal-Side Differences
Do not assume two portals contain the same puzzle, object, or reward. Inspect the left and right sides independently, and compare their visual structure. The confirmed right-side drawing makes side-specific exploration especially important, while other portal content remains undocumented and may reward careful interaction rather than route memorization.
When a portal puzzle resists, return to nearby OGAS or PEP-01 prompts. Official announcements mention revised controls for capturing X-spheres, including pressing the relevant button rather than holding it. If you are using the 2025 demo, check the current control layout before assuming an input failed because the intended object was not selected.
Lukomorye Island and Final Route
Lukomorye is the island setting named in the official gallery, and it provides a concrete destination for the later ASPIS full playthrough. The island also connects to documented achievement objectives: a freed prisoner appears at its edge, and another achievement refers to Evgeny Kotov. These clues make the perimeter worth searching carefully.
The official site also mentions a Scientist Cat and the Director. The Cat helps Andrey read the rules of the new place, while the Director guides him deeper in exchange for answers. Treat their conversations as route signals. A character who explains the rules may point toward an overlooked rule, while a guide promising deeper access can foreshadow the final choice.
| Island objective | Confirmed source | What to do |
|---|---|---|
| Search the island perimeter | A freed prisoner is tied to the island edge | Follow the shoreline and inspect isolated edges |
| Find the drawing | Achievement confirms one inside the right-hand portal | Revisit the documented side-specific portal interaction |
| hand back the Keeper’s Seal | Official achievement text | Carry the seal to the appropriate return interaction |
| Consult the Cat | Official site says the Cat explains the rules | Listen for instructions before solving a local obstacle |
| Follow the Director | Official site says he leads Andrey deeper | Track the route he authorizes or reveals |
| Prepare for one choice | Official materials state one choice and two endings | Review narrative context before committing |
Searching the Island Edge
Approach the island edge methodically, checking every visible path rather than assuming one shoreline section is the correct one. The freed-prisoner achievement is especially useful because it confirms a character interaction near the edge. Speak with the prisoner if you find them and complete the required action; simply standing nearby may not satisfy the achievement.
The edge also makes a useful return point after any missed portal or side-path search. If the finale feels abrupt, revisit the perimeter, locate unusual objects, and check whether a conversation became available after a later story beat. This avoids turning an achievement clue into an assumed linear objective.
Understanding the Final Choice and Two Endings
Official material confirms that the game ends with one choice and two endings, but it does not identify the choice, conditions, or ending names in public store details. The safest full-playthrough strategy is to follow available character dialogue, collect relevant story objects, and make the final decision only after completing the nearby objective. Do not rely on an unsourced “best ending” solution without checking the current conversation prompt.
Achievement names provide limited evidence that both conclusions are available: “Let Go” and “World on Fire” correspond to the two ending achievements. Their wording does not reveal the full plot or the exact choice, so treat the names as clues rather than a decision tree. If you want broader ending-specific context, compare it with the ASPIS final choice guide, then verify every relevant interaction in your own save.
ASPIS Full Playthrough Checklist and Verification Plan
- Search the Institute of Cybernetics, including every accessible OGAS terminal.
- Collect visible ammunition and other environmental resources.
- Inspect the KGB combination lock and verify clues in-session.
- Track down Evgeny Kotov somewhere in the tunnels and complete the relevant interaction.
- Check the packing machine and Devil’s cage achievement objects.
- Search the warehouse for resources, lore, and onward access.
- Compare the Red World, red corridor, and both sides of each portal.
- Locate the drawing inside the right-hand portal.
- Explore the edge of Lukomorye and find the freed prisoner.
- hand back the Keeper’s Seal and consult the Cat.
- Follow the Director to the final decision.
- Review the final choice and confirm the intended ending achievement.
| Verification stage | Evidence to record | Why it matters |
|---|---|---|
| Location sweep | Visited rooms, side paths, and interactable objects | Prevents missed content hidden away from the main path |
| Resource check | Ammunition and other supplies found during exploration | Confirms the environment was searched rather than merely crossed |
| Story record | Character conversations and terminal prompts | Provides evidence for the final narrative decision |
| Achievement check | Official achievement unlocks earned | Confirms specific documented interactions were completed |
| Ending check | One final choice and the resulting conclusion | Verifies the ASPIS full game was completed through its conclusion |
What the Official Material Does and Does Not Confirm
Official sources provide a reliable framework for locations, premise, equipment, interactions, achievements, and the existence of two endings. They do not publish a full chapter count, named episode list, universal KGB code, or complete portal solution chart. This distinction matters for anyone asking aspis how many chapters or aspis how many episodes: the verified answer is that the full release is not publicly organized in an official numbered list in the cited material.
The same limitation applies to a potential ASPIS full game chapter list. The 2025 demo was an extended prologue, included episode selection in a technical update, and offered up to two hours of gameplay. Those facts demonstrate that the demo contained selectable material, but they do not establish the number of episodes in the October 23, 2026 full release.
Final Verification Before the Credits
Return to every major location after reaching the finale, especially the Institute, KGB building, tunnels, and Lukomorye edge. Compare the final version of that area with your notes because some interactions may become available after later story events. Confirm that unusual objects still respond, then revisit the final conversation with the Director or the relevant character before making the irreversible choice.
The ASPIS official launch trailer can also help you recognize the project’s atmosphere and imagery, although it is not a substitute for route instructions. Use the verified location list, the achievement clues, and your own in-game observations to build a complete, evidence-based ASPIS full walkthrough.
Frequently Asked Questions
How many chapters are in ASPIS?
Official material does not publish a numbered chapter count for the full release. The Institute of Cybernetics, KGB building, tunnels, warehouse, Red World, red corridor, and Lukomorye provide a verified location-based route, but official sources do not label those places as chapters. The 2025 demo’s episode selection should not be used to calculate the full game’s structure.
How many episodes are in ASPIS?
The official full-game listing does not identify a complete episode count or publish episode names. The earlier demo included an extended prologue, up to two hours of gameplay, and a feature for choosing the episode to start from, yet these details do not reveal how the finished release is divided. For the ASPIS how many episodes question, the most accurate answer is that no confirmed full-game count is available in the cited official material.
What locations appear in the ASPIS full walkthrough?
The confirmed route includes the Institute of Cybernetics, KGB building, tunnels, warehouse, Red World, red corridor, and the island at Lukomorye. Official achievement descriptions also reference a packing machine, the Devil’s cage, a freed prisoner at the island edge, and a drawing in the right-hand portal. Treat these as exploration landmarks rather than officially numbered stages.
Is there an official KGB building lock code for ASPIS?
No code is published in the cited official sources. The achievement list confirms that the KGB building has a combination lock and can be opened quickly enough for a related achievement, but it does not reveal the sequence. Inspect nearby notes and environmental clues, and treat community solutions as unverified until the lock accepts them in your current session.
Can I finish the ASPIS full game without finding every secret object?
The official ending structure is one final choice leading to two endings, while several achievement objects appear optional. Therefore, finding every secret is not clearly required to reach an ending. However, exploring side paths improves route completion and may reveal story context, so search the packing machine, Devil’s cage, right-hand portal, island edge, and named prisoner before the finale.
