What is confirmed
Official development material identifies Unreal Engine 5, while store features list DirectX 12 requirements and modern console capabilities. Steam displays a third-party EULA but does not currently display a Denuvo notice.
What to do
Check the Steam sidebar and EULA again at launch because DRM disclosures can change. For performance decisions, rely on the named requirements and release benchmarks instead of engine-version assumptions.
What is not confirmed
Absence of a Denuvo label is not proof that no protection will ever be used. The exact Unreal Engine minor version and shader behavior are also not confirmed by the reviewed store page.
Player questions
Does The Sinking City 2 use Denuvo?
Denuvo is not disclosed on the current official Steam listing; that status should be checked again at launch.
