Easy Delivery Co.: How to Find cat.wav and Unlock Its Secret

Reading through the current cat.wav trail feels like trying to tune a weak radio signal in a snowstorm. One guide points toward MK’s house and a hidden computer, another stresses radio towers, and the clearest warning across the public walkthroughs is also the easiest one to miss: do the reboot ending before the shutdown ending. If you want the short answer first, treat cat.wav as a late-game secret chain, not a normal objective. The safest known route is to finish the main progression cleanly, unlock the later routes you need, activate every radio tower you can, preserve the ending order, and only then start checking the hidden-road route tied to MK’s house and computer.

• What cat.wav is: a hidden mystery thread tied to secret interactions, decoding, and an ending-related sequence.
• What it is not: a standard delivery, a basic collectible, or something the main route reliably hands you.
• Biggest trap: assuming normal story progress is enough, then doing endings in the wrong order.

What cat.wav actually is in Easy Delivery Co.

Easy Delivery Co. looks simple on the surface: you play a cat delivery driver hauling packages across snowy regions like Mountain Town, Snowy Peaks, and Fishing Town in a tiny kei truck. But public guides and community walkthroughs make it pretty clear that cat.wav sits in the game’s stranger, more hidden layer. It is described as a lengthy process that involves decoding, and it appears to connect to a hidden-computer and radio sequence rather than a straightforward item pickup.

That distinction matters because it changes how you should approach it. If you go hunting for cat.wav the same way you hunt for route rewards or obvious unlocks, you are likely to miss the progression flags that seem to matter more: story state, tower activation, access to hidden paths, and ending order. The current evidence also suggests this is embedded in the game’s broader mystery and possibly its secret-ending logic, so the “reward” is less about raw gameplay power and more about unlocking concealed narrative content and hidden interactions.

The safest current route to encounter cat.wav

Because the public walkthroughs are community-made and not perfectly consistent, there is no officially confirmed one-paragraph solution. What you can do, though, is follow the overlap between the available guides. That overlap is strong enough to give you a low-waste route.

• Reach late-game progression and unlock the routes that secret areas seem to depend on.
• Activate all radio towers, not just the ones that feel “story required.”
• Do the reboot ending first.
• Then investigate MK’s house, the hidden road route, and the hidden computer thread.
• Pay attention to sound and radio-related triggers instead of expecting a conventional quest marker.

Step 1: Finish the progression that opens the map properly

The first mistake players make is hunting secrets while the game still considers them under-progressed. Current public guidance suggests cat.wav is gated behind more than simple curiosity. You likely need the route unlocks and the broader late-game state that lets you reach out-of-the-way content in the first place. If a road, side area, or suspicious location still feels inaccessible, assume you are early rather than missing a magic interaction.

This is also where the game’s structure can mislead you. Since the main loop is delivering packages and slowly expanding your reach, it is easy to treat every strange lead as optional flavor. For cat.wav, that seems wrong. Think of this secret as something that checks whether you have engaged with the map deeply enough to deserve the next layer.

Step 2: Activate every radio tower you can reach

Radio towers are one of the strongest recurring pieces of evidence in the current walkthrough ecosystem. One public guide says there are four towers, with three tied to story progress and the fourth potentially mattering for completionist or secret progression. Another points more broadly to tower activation as part of later secret access. Put those together, and the practical advice is simple: if you are chasing cat.wav, do not stop at the three that feel mandatory.

Even if one day it turns out the fourth tower is not strictly required, activating all of them is still the safest play because it removes one of the most obvious hidden-state blockers. When a secret is radio-themed and multiple guides keep circling back to towers, leaving one unfinished is asking to waste time somewhere else.

Step 3: Take the reboot ending before shutdown

This is the one warning I would treat as non-negotiable. The most detailed public guide available reportedly says to do the reboot ending first and specifically warns against taking the shutdown ending first. That tells you the sequence is probably order-sensitive, which is exactly the kind of thing secret chains love to hide.

If your platform or version gives you any way to preserve a backup save before ending choices, use it. Not every release handles saves the same way, and there is still uncertainty around the minimum required route, but losing the correct ending order would be the most painful place to discover you needed a different setup. If you have already done shutdown first, assume that may be the reason the chain is not behaving as expected.

Step 4: Check MK’s house and the hidden-road route carefully

Current guides repeatedly connect cat.wav to MK’s house, a hidden computer, and a hidden road route. That does not sound like random flavor text. It sounds like a deliberately tucked-away leg of the puzzle chain. So once your progression, towers, and ending order are in place, start thinking like the game is hiding infrastructure rather than loot: off-path access, weird architecture, rooms or objects that look too specific to be decoration, and any location that feels like it belongs to the mystery rather than the delivery economy.

The important detail here is hidden road. Players often comb the obvious path and conclude the guide is wrong, when the real issue is that the route itself is part of the puzzle. If you know MK’s place is involved, but you are approaching it from a normal route and getting nothing useful, back up and assume the approach matters as much as the destination.

Step 5: Treat sound and radio cues as part of the puzzle

The file name itself points you toward audio, and the public descriptions connect the secret to radios, decoding, and sound triggers. That means you should not play this section on autopilot. Keep game audio clear, linger near suspicious devices or hidden objects, and do not assume an objective marker or big text prompt will confirm every successful step. Some secrets in games announce themselves with fanfare; this one sounds more like it expects you to notice signal rather than spectacle.

That is also why cat.wav feels different from a normal Easter egg. The secret seems designed to be interpreted, not merely found. If a guide mentions decoding, believe it. You are not only locating a place; you are engaging with the game’s hidden language.

How cat.wav performs and why players care

If you came here wondering whether cat.wav is a weapon, truck upgrade, or stat reward, the best current answer is no-or at least there is no strong public evidence that it functions that way. cat.wav appears to “perform” more like a secret-layer trigger than a conventional piece of gear. Its role is tied to the game’s hidden-computer and radio mystery, and it seems connected to late-game ending structure rather than to improving routine deliveries.

That makes it valuable for a different reason. In a game whose tone mixes cozy driving with low-key unease, cat.wav looks like one of the threads that justifies digging beneath the surface. For completionists, it matters because it may intersect with achievement planning and optional late-game content. For mystery hunters, it matters because it seems to expose how the game’s secrets actually talk to one another: towers, hidden routes, computers, endings, and sound.

Troubleshooting when cat.wav will not progress

If the secret is refusing to move, do not immediately assume you missed one tiny click. The bigger blockers are more likely to be systemic.

• You only activated the story towers: go back and finish the fourth tower as well.
• You chased MK’s house too early: make sure later routes and hidden-road access are actually available.
• You took the wrong ending first: current public guidance strongly favors reboot before shutdown.
• You expected a normal quest flow: this chain appears to rely on hidden objects and non-obvious triggers.
• You rushed past audio clues: revisit suspicious locations with sound and radio details in mind.

The other thing to keep in mind is that public guides do not line up perfectly. One source frames the whole matter around MK’s hidden computer and sound triggers, while another leans harder on tower completion and broader progression. Those accounts probably describe the same mystery from different entry points, but until an official breakdown exists, you should assume the secret chain is both multi-step and slightly brittle.

What is still uncertain

The broad structure of the cat.wav route is fairly solid: late-game state, radio towers, MK-related hidden content, and ending order all show up often enough to take seriously. The exact minimal path is still less certain. Community sources differ on which tower steps are mandatory, how early you can start the sequence, and how tightly the hidden-computer thread is locked to specific endings.

So the right way to approach this, at least for now, is not to hunt the mythical shortest route. It is to remove every likely blocker first. In practice, that means over-preparing instead of trying to shave steps off a secret chain that already has a reputation for being long and decoding-heavy.
