The Walking Trade Guide — How to Heal Customers

The Walking Trade is a singleplayer, first-person store management simulation from developer Microwave Games, published by PlayWay S.A. and released on Windows on March 5, 2026 for $11.99. You run a shop in a zombie apocalypse: trade batteries, craft stock in the backroom, hire staff, expand the building, and fend off undead hordes. This The Walking Trade guide explains the systems that matter, the order to unlock them in, and how the game handles customers who get hurt during an attack.

What kind of game The Walking Trade is

The Steam store describes the premise in one line: "Run a shop in the zombie apocalypse! Trade batteries, craft stock, manage your staff, and fend off undead hordes." It is built in Unity and tagged as an indie business and simulation game with a cartoon art style and a post-apocalyptic theme. The camera is first-person, the pacing is real-time, and control is direct rather than menu-driven.

Review coverage from The Guide Hall scored the game 8 out of 10 and called it "an interesting take on the store management simulation genre, sometimes a little chaotic, a bit buggy in places, but overall an enjoyable experience." The same review describes the presentation as a low-poly art style that suits the apocalypse setting, with characters wearing stitched clothing, worn armour and visible injuries.

Two practical details matter before you buy. First, a demo is available on Steam, so you can test the store loop without committing. Second, monetisation is a one-time purchase with no microtransactions, per PCGamingWiki's taxonomy tables.

The core loop: batteries, stock and staff

Batteries are the money. The Guide Hall review explains that "the more currency (batteries) that you bring in, the more you can reinvest," and that you can buy key supplies from other traders, pay staff more, and unlock passages through the city to reach better goods. Not every battery works, and the review notes the game gives you recourse when one is dead.

Stock comes from four places: crafting in the backroom, scavenger runs into the city, searching trash, and the glowing points scattered around your own store that hand out basics such as beer. Staff split into three rough roles that the review names directly:

• Scavengers, who go out into the world and bring back goods, sometimes useful and often not.
• Guards, who defend the shop and the lot when zombies arrive.
• Service professionals, who handle the store-facing work so you can craft, build and fight.

Customers arrive once you have shelving and products in place, and the review's early-game order is cleaning, then shelving, then products, then customers. There is no documented way to hand a customer a weapon or a cure directly; the systems that matter are stock, staff and building upgrades.

How to heal customers in The Walking Trade

The short answer is that The Walking Trade does not document a heal-customer mechanic. Nothing in the store page, the achievement list, the patch notes or the review coverage describes a station, item or keybind that restores health to a customer. If a customer is hurt, the documented response is prevention and rescue rather than treatment.

The one officially tracked customer-safety action is saving a customer from an aggressive zombie, which unlocks the achievement Customer Comes First. That makes the practical advice simple: keep guards hired and positioned, keep the store reachable, and deal with the zombie that has grabbed a shopper before it finishes the job.

A community thread on the Steam forums suggests the developers could go further. In a May 2026 "Ideas For The Game" post, a player asked to "convert the medical ward to a real service of healing for clients" and separately floated selling and stocking the cure with refrigeration. Those are player requests, not shipped features (to confirm), so treat any claim about a working medical ward as unverified. Until the developers document otherwise, plan around guards, distance and weapons rather than a healing station.

Store upgrades, expansions and reputation

Upgrading the stations around your store is the main progression axis. A popular Steam guide called Upgrade Guide opens by saying that "upgrading the stations around your store is essential to getting the most out of The Walking Trade," and lists the items each station needs. Costs scale hard: the review gives the example of needing 96 sawblades for the recycler while drowning in unlabelled cans.

The achievement list is the cleanest public map of the progression milestones, because each one is tied to a permanent unlock:

Milestone	Achievement	What it means
First customers	Welcome to Retail Hell	Serve 5 customers
First craft	Arts & Crafts	Craft an item
Warehouse access	Backroom Privileges	Gain access to the warehouse
Store expansion	Open Floor Plan	Hire the demolition crew to expand your store
Hospital access	That's What That Noise Was!	Gain access to the Hospital
Warehouse power	Backdoor Access	Fix the Generator in the warehouse
Reputation	Local Legend	Reach 75% reputation
Bed upgrade	Luxury, Sort Of	Upgrade the bed to a Bedroll
Shop furniture	Impulse Buyers	Build a Basket Stand for your shop

Two of those deserve emphasis for new players. Open Floor Plan requires hiring the demolition crew, which is the gate on expanding the physical store, and Local Legend asks for 75% reputation, which means reputation is a tracked stat you should protect rather than ignore.

Surviving raids, hordes and Hardcore mode

Zombies are not background decoration. The review describes both stragglers that stumble into the lot and wave-based hordes that require a real fight. Achievements name several specific attacks: a Zombie Horde in the city, the Brute Army raid, the Broody Birthers raid, the Twin Terrors raid and the Sweaty Rotter raid. Defeating a raid is its own achievement, Live Another Day!.

The most-repeated community tactic comes from the Steam guide Easily Win Raids, which advises collecting a ranged weapon and plenty of ammunition, climbing the ladder outside the shop onto the cargo containers, and shooting from the top of the container so the zombies cannot reach you. That is a position-based answer rather than a damage answer, and it lines up with the achievement requirement to defeat a raid without dying on Hardcore Mode.

Hardcore mode is the difficulty spike worth planning for. Two achievements are tagged as difficulty specific: Ten Days, Zero Chill for reaching Day 10 on Hardcore Mode, and No Refunds, No Respawns for defeating a zombie raid on Hardcore without dying. The community has also produced guides on saving your game in Hardcore mode, which tells you how unforgiving the default save behaviour is. Build your defence and your stock before you switch difficulties, not after.

What to fix first if the game misbehaves

The Walking Trade is an indie release that has been patched aggressively since launch, and the hotfix notes are a useful troubleshooting reference. Hotfix 1.2.8 stopped cleaners from looping when placing items on shelves in the first and second room extensions. Hotfix 1.2.7 made items that fall out of the map or explode far away return to the front of the store, fixed multi-crafting with materials on pallets, and added a male or female player voice option in the language settings. Hotfix 1.2.6 upgraded the engine version to address memory leaks that caused crashes after long sessions and reworked pallet physics.

The review's own bug list is worth knowing so you can tell a known issue from a broken save: items spinning and getting stuck in the ceiling, the in-game clock freezing, characters becoming stuck in the environment, and customers pushing the player around. In the reviewer's case a restart fixed it. If your save data itself is the concern, PCGamingWiki lists it under %USERPROFILE%\AppData\LocalLow\Microwave Games\The Walking Trade\Sync, with Steam Cloud using around 95 MB.
