Our verdict on CoSMOS

CoSMOS is a free desktop game memory editor for modifying values in running PC games. It is designed for both beginners and experienced game hackers, with support for Windows and Linux. Its core toolkit covers memory scanning, value filtering, editing, and freezing, while the broader feature set adds debugging, scripting, code injection, disassembly, and table management. The product has been available since 2001 and is offered by Cheat Happens, also identified as Dingo WebWorks, LLC.

The feature depth is its main strength. Users can work with a VEH debugger, script engine, script editor, disassembler, dump viewer, and searches for strings and address references. CoSMOS also exposes threads, handles, modules, and memory regions, giving advanced users more visibility into running processes. Cheat table import and export supports reusable table-based workflows, and the built-in speedhack extends the tool beyond straightforward value editing. This makes CoSMOS a broad editor rather than a narrow scanner.

Platform fit is another important consideration. The PC version supports Windows, while the Steam Deck version is a native Linux application; separate PC Beginner, PC Advanced, and Steam Deck versions are available. That edition structure matters when choosing how to run the tool and which feature set fits the intended use. CoSMOS should suit users who want a free editor with scripting, debugging, injection, and table support. It is less suitable for someone seeking a general-purpose desktop utility outside running PC games or a single, undifferentiated edition across platforms.
