Interdimensional Vending Machine is one of those games that completely changes once you understand what it’s actually about. During the first hour, many players assume they’re supposed to survive, manage hunger, stay hydrated, and help everyone around them avoid mutations. The game certainly looks like it’s setting you up for that kind of experience.
Then you discover that the exact opposite is true.
Your goal isn’t to avoid transformations. Your goal is to embrace them. Every route, mutation, ending, achievement, and major progression system revolves around feeding yourself increasingly bizarre items from the vending machine and seeing what happens next.
The game doesn’t explain many of its systems very well, which is why so many new players end up confused about progression. This guide breaks down everything from unlocking areas and farming money to discovering routes, earning achievements, and eventually reaching 100% completion.
Interdimensional Vending Machine Walkthrough & Achievements
Before chasing achievements, it’s important to understand the core gameplay loop.
You play as a homeless person surviving on the streets.
The main gameplay cycle is:
- Beg for money.
- Spend money at the vending machine.
- Consume items.
- Trigger mutations.
- Unlock routes.
- Discover endings.
- Ascend and repeat.
Unlike traditional survival games, mutations are progression. The more mutations you discover, the more content becomes available.
Item Numbers Are Random
One of the most important things to know is that vending machine item numbers are randomized.
If someone tells you:
- 52 Yen = Moldy Sandwich
- 100 Yen = Specific Drink
Those numbers may only work in their save.
The safest method for discovering items is testing values such as:
- 1
- 10
- 50
- 100
- 200
- 300
- 400
- 500
- 600
- 700
- 800
- 900
- 1000
- 2000
Once you discover an item in your save, record its value for future use.
First Steps: Unlocking Every Area
Your first major goal should be unlocking all locations.
Many achievements, NPCs, and routes require areas that aren’t available at the start.
Main Street
This is where your journey begins.
Immediately talk to the elderly woman.
Give her any item.
Doing so unlocks:
- Empty Street
- Dark Street
Before leaving, collect the nearby card if it’s available.
Empty Street
After earning some money, visit Empty Street.
Go left and speak with the starving man.
Feed him any food item.
Continue his dialogue until all conversation options are exhausted.
This unlocks:
- Apartments
Apartments
The Apartments introduce one of the most important progression gates.
You must save:
- 2,000 Yen
Paying this amount grants access to:
- Hotel Room
- Mall Entrance
Mall Entrance
Head left after arriving.
You’ll find a transformed child.
Feed the child.
Doing so unlocks:
- Busy Street
- Corner Merger
The child later becomes one of the best NPCs for making money.
Busy Street
Travel to Busy Street.
Go left and locate two NPCs.
Feed them.
This unlocks:
- Farthest Street
At this point, you have access to almost every important location in the game.
Understanding NPC Hunger Forms
Most NPCs have multiple appearances.
Their appearance changes depending on how much food you’ve given them.
This system is mostly cosmetic.
However, feeding NPCs often unlocks:
- New locations
- New rewards
- Additional dialogue
Best Food for NPC Feeding
Apple Seeds are generally the most efficient choice.
They are cheap, easy to obtain, and work on nearly every NPC.
The Best Money Farming Method
Money eventually becomes the most important resource in the game.
While normal begging works, there’s a much faster method.
Step 1: Start the Rotten Route
Find Rotten-type items.
The easiest example is usually a Moldy Sandwich.
Consume enough to reach:
- Mutation Stage 2
- Mutation Stage 3
Step 2: Increase Danger Levels
Once mutated:
- Beg constantly.
- Enable x2 speed.
- Raise danger levels.
Higher danger levels increase rewards and unlock more vending machine content.
Danger System Explained
The danger meter appears in the upper-left corner.
As mutations become more extreme:
- Danger rises.
- More items appear.
- More endings become available.
Danger stages escalate gradually.
Early mutations cannot exceed certain thresholds.
More advanced mutations unlock higher danger caps.
Understanding Danger Warnings
While begging at high danger levels, warning messages appear.
The first warning is harmless.
Ignore it.
Eventually, however, repeated warnings can trigger:
- Capture endings
- SCP endings
- Neutralization endings
The exact result depends on your mutation route.
The Crow Investment Strategy
This is the single best money-making strategy in the entire game.
First Investment
Visit Dark Street.
Find the Crow.
Give him:
- 10,000 Yen
Return the next day.
You’ll receive:
- One 10,000 Yen coin
This saves enormous amounts of clicking compared to manually inserting thousands of coins.
Turning Coins Into Apple Seed Bags
Insert the 10,000 Yen coin into the vending machine.
You’ll receive:
- Large Apple Seed Bags
Give these bags to the elderly woman.
The reward is significantly larger than your initial investment.
Upgrading to 50,000 Yen
Later, give the Crow:
- 50,000 Yen
This unlocks another achievement and provides even better profits.
Once this strategy is available, money effectively stops being a problem.
Apartment Features
Many players rent the apartment and never explore it fully.
Refrigerator
Inside the apartment is a refrigerator.
Placing any item inside unlocks an achievement.
Simple but easy to miss.
How Ascension Works
Ascension is one of the most important progression systems.
After performing a Rebirth:
- Choose Ascension.
- Unlock a new route.
- Expand the item pool.
You’ll need multiple Ascensions to discover everything.
Why Ascension Matters
Many vending machine items are locked behind Ascension routes.
Without repeated Ascensions:
- Some mutations never appear.
- Certain achievements remain impossible.
Item Categories Explained
The vending machine groups items into categories.
Different Yen values pull from different item pools.
These categories contain:
- Food
- Drinks
- Mutation items
- Angelic items
- Demonic items
- Route-specific items
Because item numbers vary between saves, experimentation is required.
Route Guide
Rotten Route
One of the earliest routes.
Triggered by consuming rotten or moldy foods.
Effects:
- High danger growth
- Excellent money farming
- Easy progression
Water Route
Triggered through water-based consumables.
Many drinks contribute.
The final mutation stage unlocks a route achievement.
Rodent Route
Triggered through rat-themed foods.
This eventually unlocks:
- Neutralized Ending
Demon Route
Requires Demonic items.
Usually found through higher-value machine purchases.
Reaching the final stage unlocks the Demon route achievement.
Angel Route
Uses Angelic items instead.
Functions similarly to the Demon route.
Starvation Route
One of the strangest routes.
Simply stop eating.
When hunger reaches zero:
- Stage 1 begins.
- Mutation progresses automatically.
There are seven total starvation stages.
Perfection Route
Arguably the strongest route in the game.
Benefits include:
- Massive begging income
- Safer farming
- Easier achievement grinding
This route is recommended for most money-related achievements.
Avarice Route
Built around greed-themed items.
Eventually leads to unique ending scenarios.
Every Major Ending
Several endings are obtained by intentionally allowing authorities to react to your mutations.
Captured Ending
Mutate heavily.
Continue begging.
Ignore warning messages.
Eventually you’re arrested.
Neutralized Ending
Most commonly earned through advanced Rodent mutations.
Containment Ending
Often referred to as the SCP ending.
Requires extreme danger levels.
Demonic Ending
Requires high-level Demon mutations combined with danger escalation.
Angelic Ending
Requires high-level Angel mutations combined with danger escalation.
Achievement Guide
Stealing Achievement
Visit Empty Street.
Find the blind beggar.
Steal from him repeatedly.
Requirements:
- Only once per day.
- Total stolen amount must eventually reach 10,000 Yen.
Clone Achievement
Visit the armed man near the Mysterious Tree.
Provide the requested item.
Clone it.
Return it.
Achievement unlocked.
Refrigerator Achievement
Store any item in your apartment refrigerator.
Begging Achievements
Several achievements unlock at money milestones.
Using the Perfection Route makes these incredibly easy.
Item Collection Achievements
The game contains hundreds of discoverable items.
Most players earn:
- 100 Items
- 200 Items
Naturally.
The 300-item achievement requires significantly more route completion.
How to Reach 300 Items
Visit Farthest Street.
Speak with the mysterious NPC there every day.
He provides additional item discoveries.
Combined with:
- Ascensions
- New routes
- Vending machine experimentation
You’ll eventually reach 300 unique items.
Achievement Warning: The Million Yen Reset
One achievement is extremely dangerous for completionists.
Spending:
- 1,000,000 Yen
Resets your game.
This removes:
- Route progress
- Item collection
- Unlock progress
Always leave this achievement for last.
Many players accidentally trigger it too early and regret it immediately.
Fastest Path to 100%
If you’re aiming for full completion, follow this order:
- Unlock all locations.
- Complete Rotten Route.
- Unlock Crow investments.
- Rent the Apartment.
- Unlock every route through Ascension.
- Complete all route mutations.
- Earn every ending.
- Collect 300 items.
- Complete money achievements.
- Trigger the reset achievement last.
Following this order minimizes grinding and prevents accidental progress loss.
Interdimensional Vending Machine is far deeper than it initially appears. What starts as a strange game about a homeless person buying food quickly evolves into a massive achievement hunt centered around mutations, transformations, route discovery, and bizarre endings. Once you understand how Ascension, danger levels, Crow investments, and mutation routes interact, the entire game opens up.
For most players, the biggest turning point is realizing that becoming a monster isn’t failure. It’s progression. The sooner you embrace that idea, the faster you’ll unlock every route, ending, item, and achievement on the road to 100% completion.
