Here is a "useful story" about what usually happens when you click "Download" on a file like Cuphead.v1.3.4.Incl.ALL.DLC.zip . The "Free" Game Trap

: Cuphead frequently goes on sale for significant discounts on official storefronts. You get a clean, safe file and support the artists at Studio MDHR who spent years hand-drawing every frame.

: Unlike the official version on Steam or GOG , these "Incl.ALL.DLC" zip files are often used as "wrappers" for malware. The game might actually run, but in the background, a script installs a Trojan or a Keylogger .
