KOTAMON: My Sis Found A Super-Rare Card In Her Cereal Box, So I Became A Garbage Man To Find The Entire Collection Download

Clearing trash can feel even better when you not only make the world cleaner, but also find extra-rare cards that have suddenly increased in price! Rummage through garbage, fulfill the orders from the dump site owner, look for hidden treasures... and collect all the Kotámons!

Game Overview

1. KOTAMON is a first-person collecting simulation game developed by KotaMota Games and published by Polnoch, released on Steam on August 21, 2026. The game features a delightfully absurd premise: your sister Mota pulled a super-rare card from a cereal box but accidentally threw it away. Now you play as Kota, a garbage man working at Jenny's dump site, searching through mountains of trash to recover the lost card and complete the entire collection for a $1,000,000 reward.
2. With a title totaling 134 characters including spaces and punctuation, KOTAMON may hold the record for the longest game name on Steam. The game has already garnered significant attention, reaching a peak of 4,832 concurrent players and earning a "Very Positive" rating from Steam users with 80% positive reviews. It supports multiple languages including English, Japanese, and Simplified Chinese.
3. The game offers approximately 10 GB of storage space and is available at a launch discount. An official soundtrack composed by Kate Yantser is also available as a separate purchase.

Gameplay & Mechanics

1. The core gameplay loop involves approaching towering garbage piles, grabbing onto them to trigger a 3D model transformation, and then rummaging through various types of trash including milk cartons, empty cans, pizza boxes, and more. You collect garbage into bags and deposit them into a compactor to earn money. The game uses a first-person perspective, and players can adjust FOV and other settings for comfort.
2. Earned money can be spent on upgrading various stats including garbage bag capacity, stamina, garbage pickup speed, and beer recovery amount. Stamina depletes as you work and can be restored by drinking beer, with upgrades increasing recovery efficiency. The game features no time limits, allowing players to explore at their own pace.
3. A demo version is available for players to try before purchasing. The game includes manual save functionality with four save slots, though autosave timing may be inconsistent. Developers have been actively releasing patches to fix bugs and improve the user interface.

Card Collection & Restoration

1. The primary objective is finding Kotamon trading cards hidden within garbage piles. Cards can be discovered in multiple ways: found intact, assembled from five fragments collected across the dump, or restored by cleaning dirt and damage at your workbench. Better-condition cards fetch higher prices when sold.
2. There are dozens of unique cards featuring hand-drawn illustrations. Cards come in multiple color sets and rarity tiers. If you're exceptionally lucky, you may find unopened cereal boxes containing super-rare foil cards. The game also features a card exchange system that was available from launch but lacked a tutorial—developers have since added tutorial prompts and visual indicators for tradable cards.
3. Beyond cards, the dump site contains other collectibles including miniature figurines that can be displayed on shelves and cosplay costumes that can be worn by Jenny, the dump site owner. After clearing all garbage in an area, you can request Jenny to replenish new trash piles, enabling endless treasure hunting.

Progression & Upgrades

1. The game features a gradual progression system where upgrades become progressively more expensive. Some players have noted that the grind can feel slow, with upgrade costs doubling frequently while stat increases remain modest. The economy and card drop rates have been adjusted through post-launch patches to improve the experience.
2. Efficient gameplay involves strategic decisions such as filling bags completely before depositing them into the compactor or throwing bags from a distance. The game's cozy atmosphere is enhanced by a relaxing soundtrack that fits the theme of cleaning and organizing.
3. Developers have been responsive to community feedback, adding features like card exchange tutorials and visual indicators. They've also fixed bugs related to disappearing cereal boxes and adjusted the drop rates for cosplay suitcases. Steam trading cards are also being prepared for release.
