Quick take
- Steam requires agreement to a third-party EULA.
- No specific additional DRM product is named by the reviewed pages.
The confirmed Steam requirement
It does not answer every question covered by the broader term DRM.
The storefront legal notice
Steam marks the product as requiring agreement to a third-party EULA and links the game's EULA. A EULA requirement is a contract notice. It is not, by itself, the name of an anti-tamper product, an always-online requirement, or a statement about ownership beyond the EULA's own terms.
The undisclosed part
Because that answer is incomplete, this page is noindex.
