Easy Delivery Co.: How to Track the Cat.wav Secret Puzzle Chain

Cat.wav is the progression marker for Easy Delivery Co.‘s hidden ending chain. The reliable way to handle it is to treat radio towers, MK’s computers, hidden systems, and the Factory as separate checks in one ordered state sequence. A tower you can reach is not automatically the tower your save currently needs, and a computer that does not advance usually points to an earlier missing state rather than a ruined run.

The confusing part is that this secret route is commonly presented as isolated discoveries: a radio tower here, an MK terminal there, a Factory visit somewhere later. That presentation hides the dependency between them. Cat.wav is the thread that connects those discoveries into the game’s secret or “true ending” route.

What Cat.wav Is Actually Tracking

Cat.wav should be read as a progression condition, not as a single collectible or one-off audio clue. Its chain is built around four linked systems:

• Radio towers, which form the visible exploration gates.
• MK’s computers, which function as confirmation points for hidden progression.
• Hidden computers, bunkers, and cat-related objects, which expand the secret layer beyond the normal delivery loop.
• The Factory, which acts as the late-stage destination for the chain.

The game’s delivery progression and the Cat.wav route overlap geographically, but they are not interchangeable. Improving the truck, opening a route, or gaining the ability to cross difficult terrain may solve an access problem. It does not prove that the Cat.wav state has advanced. That distinction accounts for a large share of failed attempts to force the next computer or Factory event.

The Cat.wav Chain, Broken Into Verification Phases

Use these phases to identify the last confirmed point in the chain. The goal is to establish what your current save has actually registered before repeating travel, spending money on an unnecessary upgrade, or restarting.

Phase 1: Establish the Cat.wav and Tower State

The first phase concerns the radio network. Towers are the easiest part of the chain to spot, which makes them the most likely source of a false assumption. Reaching a tower, seeing it from the road, or gaining access to its region are different conditions from activating the tower at the point required by the secret sequence.

For each tower relevant to your run, record only confirmed actions: whether you reached it, whether it was activated, and whether anything in the game visibly changed afterward. Do not mark a tower as complete because a route is now driveable or because another guide moves on from that area. The Cat.wav chain cares about registered progression, not travel distance.

Common trap: pursuing a difficult tower because it is the most obvious remaining landmark. A later tower can remain inert if the save still expects an earlier Cat.wav condition. In that situation, better handling, extra traction, or repeated attempts at the climb only address the wrong problem.

Phase 2: Use MK’s Computers as State Checks

MK’s computers are the most useful diagnostic points in the route. They indicate whether the preceding Cat.wav and tower work has been accepted by the save. Treat each computer as a checkpoint rather than an independent secret.

If a computer produces a new response, note it immediately and move your record forward one phase. If it produces no meaningful change, do not assume the terminal is broken. Return to the last tower or Cat.wav-related trigger you can verify. The missing piece is usually behind you in the sequence, even when the computer itself is located in an area you can already access.

• A computer that advances the chain confirms that the prior state was valid.
• A computer found early can remain inactive until the relevant tower state exists.
• A computer revisited after later exploration may look like a new discovery, even when it was meant to be checked earlier.
• A screenshot or written note from a later phase can omit the earlier computer state that made the interaction possible.

Phase 3: Confirm the Hidden Layer Before Pushing the Factory

Once towers and MK’s systems are being checked in sequence, the route moves into the game’s less visible puzzle layer: hidden computers, bunkers, and the cat-related objects tied to the mystery. This is where a normal exploration route and a Cat.wav route can look identical from the outside while producing different results.

Do not evaluate this phase by whether you have physically found a hidden location. Evaluate it by whether the earlier chain produced a new state for that location. The practical question is not “Can I enter this place?” It is “What did the game acknowledge after I entered it?”

This is also the point where players can mistake a missing condition for a softlock. A hidden computer or bunker that does not supply the expected progression may be waiting on an unverified tower or an MK computer state. Restarting at that point discards useful progress without proving that the save was blocked.

Phase 4: Treat the Factory as the Resolution Check

The Factory belongs at the end of the verification chain. It is a destination for the secret route, but arriving there early does not establish that the route is ready to resolve. The Factory can be physically available while the Cat.wav sequence remains incomplete.

Before treating the Factory as your next mandatory step, verify three points: the required tower state is recorded, MK’s relevant computer progression has advanced, and the hidden layer has produced its expected acknowledgement. If one of those is uncertain, the Factory is a diagnostic location rather than a final destination.

Why Cat.wav Walkthroughs Conflict

Conflicting Cat.wav advice usually comes from collapsing a state-dependent sequence into a location list. A location list can show every important tower, terminal, and building while still failing to explain which one matters first.

Later Progress Is Often Shown Without Its Prerequisites

A guide can correctly identify a tower or MK computer while leaving out the Cat.wav state that made it responsive. Following that entry from a fresh or differently progressed save produces the familiar failure: you arrive at the correct place and receive no advancement.

The correction is simple: use a later location only after your save has passed the earlier phase checks. Do not substitute proximity for sequence.

Traversal Requirements Get Mistaken for Puzzle Requirements

Easy Delivery Co. uses truck upgrades and difficult driving conditions to control access to parts of the map. That makes it easy to assume every inaccessible tower is an upgrade test. Sometimes it is. In the Cat.wav route, though, a needed upgrade only answers whether you can reach a place; it does not answer whether that place is the active part of the mystery.

Keep two separate notes: access, meaning what the truck can currently reach, and secret state, meaning which Cat.wav, tower, and computer checks have visibly advanced. Mixing those two records leads directly to wasted detours.

The Factory Looks Like a Starting Point When It Is a Late Check

The Factory is prominent enough to attract early exploration, and that makes it a natural point for incomplete instructions. Its role in the Cat.wav chain is clearer when treated as a resolution check. If the expected result is absent, return to the tower and MK-computer record before searching for a different Factory interaction.

How to Audit a Save Before Restarting

A clean audit takes less effort than replaying the delivery progression from the beginning. Write down the last event that clearly changed the game’s secret-state behavior, then work forward from there. Avoid relying on memory; this chain is built from small, easy-to-misorder interactions.

• Cat.wav: identify the last Cat.wav-related condition you know was completed.
• Radio towers: separate towers you saw or reached from towers you know were activated.
• MK’s computers: note the last computer that clearly acknowledged a progression change.
• Hidden systems: record whether a hidden computer, bunker, or cat-related discovery changed after the confirmed computer state.
• Factory: record what happened there after the prior phases, rather than treating a visit alone as completion.
• Truck access: list upgrades separately so they do not get confused with secret-route flags.

After this audit, resume from the first uncertain phase rather than from the furthest location you can access. If the last confirmed state is an MK computer, verify what that computer unlocked before attempting another radio tower. If the last confirmed state is a tower, check the appropriate computer response before treating the Factory as unfinished content.

False Softlocks and Actual Progress Problems

A Cat.wav run can look stalled for several reasons. The important distinction is between a missing state and a genuinely unusable save.

• False softlock: a computer, bunker, or Factory check does nothing because its prior tower or Cat.wav condition was never registered.
• Wrong-branch stall: an accessible tower or hidden area is pursued because it appears next on a map, despite the sequence expecting another state first.
• Access stall: the destination is correct, but the truck cannot yet make the approach reliably.
• Record-keeping stall: the relevant progression happened earlier, but the player cannot tell which of several towers or terminals was the last valid trigger.

The first three cases are corrected by returning to the earliest uncertain phase. The fourth is prevented by recording visible changes as they happen. A restart should be the last response, not the first, because a save that appears stalled may only need its tower and MK-computer order reconstructed.

Keep EasyCo EasyRally Separate From Cat.wav Progress

The free EasyCo EasyRally update adds rally-style driving physics, time-trial races, cinematic replays, and new music by Sohaoying. It is useful to keep those activities separate from a Cat.wav progress record. Rally handling changes how a difficult road or tower approach feels, while the secret route is tracked through its tower, computer, hidden-system, and Factory states.

That separation matters when revisiting difficult terrain. A cleaner drive or a newly manageable route can make it feel as though the secret has advanced. For Cat.wav, only a confirmed interaction or changed puzzle response should move your checklist forward.

Cat.wav Progress Checklist

• Confirm the Cat.wav-related state before pursuing a later landmark.
• Mark radio towers as activated only when the game acknowledges the interaction.
• Use MK’s computers to verify that the previous phase registered.
• Check hidden computers and bunkers only after their prior state is confirmed.
• Use the Factory as a late-route resolution check.
• Track vehicle access separately from secret-puzzle progress.
• Return to the first uncertain phase before restarting a save.

The Cat.wav route is solved by maintaining its order: Cat.wav state, tower confirmation, MK computer verification, hidden-system progression, then Factory resolution. Any guide that skips one of those checks can send a valid save toward the wrong tower, the wrong upgrade, or an early Factory visit.
