About Catto Boi Collection
Catto Boi Collection is a Steam‑exclusive psychological horror series starring a small cat who gradually discovers a twisted world. The five games unfold chronologically, beginning with The Adventures of Catto Boi and concluding with Requiem, and feature disturbing imagery, audio, moderate language, and fourth‑wall breaks intended for mature audiences.
The series runs on Windows PCs and supports both any XInput‑compatible controller and standard keyboard‑mouse input. Features include Steam Achievements, custom volume controls, the ability to save at any time, stereo sound, and family sharing. The games are safe for hardware, though they read the local user account name for immersion.
01 / THE GUIDE
Narrative Structure
The collection links five distinct titles in chronological order, each adding new layers to the unsettling story. The games follow Catto Boi as he searches for biscuits and pearls while confronting a world that becomes increasingly sick and twisted.
The description notes that the choices made in each game will matter in the end, implying that player decisions across the titles have some influence on the final outcome, though the exact nature of that influence is not detailed.
- Take note of recurring symbols; they often hint at deeper connections between games.
- Write down major decisions to help recall how they might affect later chapters.
02 / THE GUIDE
System Requirements
The series recommends at least 4 GB of RAM, a processor comparable to an Intel Core i3 or better, and 10 GB of storage for decent gameplay. It runs on Windows but is not supported on Chromebooks, macOS, or mobile devices.
Linux users may attempt to run the games through Steam’s Proton compatibility layer, though this has not been fully tested. The use of a virtual machine is discouraged because it can degrade the experience.
- Close unnecessary background programs to free RAM before launching.
- If using Proton, verify the compatibility settings for each title.

Input Options
The collection can be played with any XInput‑compatible controller (such as an Xbox™️ controller) or with a standard keyboard and mouse. Both input methods are supported throughout the series, allowing players to choose their preferred device.
Certain sections explicitly require keyboard‑mouse input to progress, confirming that the game can be fully completed without a controller. The presence of a Keyboard Only Option reinforces this capability.
- Use the mouse for puzzle sections that need precise clicking.
- Switch to a controller for exploration segments if you prefer analog movement.
04 / THE GUIDE
Steam Achievements
Steam Achievements are integrated into the series, allowing players to earn recognitions for completing specific actions or reaching narrative milestones across the five games.
These achievements are displayed on the Steam platform and serve as a record of progress, but the description does not specify any effect on gameplay balance.
- Review the achievement list before starting a new title to set personal goals.
- Check your Steam profile after each session to see which achievements you have unlocked.
05 / THE GUIDE
Save System
The series offers a "Save Anytime" feature, letting players pause and resume the experience without timed pressure. The source does not specify where saves are stored or how they are accessed.
Because saving is unrestricted, players can choose moments that feel appropriate for recording their progress, especially before major decision points that may influence later outcomes.
- Save before making a significant choice to ensure you can revisit that point later.
- Take advantage of the ability to save at any time to manage play sessions around your schedule.
