What is actually confirmed

Epic lists an Epic ID requirement for the PC product. That account requirement is not itself a statement about Denuvo anti-tamper technology. We found no explicit Denuvo declaration in the reviewed official description.

Why unrelated reports are excluded

The search snapshot included discussions about other games and publishers with “Abyss” in their names. Those do not establish End of Abyss DRM. Claims copied from a similarly named title are excluded from this answer.

How to make a DRM-sensitive purchase decision

If anti-tamper software is decisive for you, ask the publisher or inspect an official updated notice before buying. We cannot promise offline launch behavior, absence of activation checks or performance effects without a relevant source.
