Diablo III: Eternal Collection is an action RPG developed by Blizzard Entertainment, released in 2017 for PlayStation 4, Xbox One, Nintendo Switch, and PC. The package bundles the base game, Diablo III, together with the Reaper of Souls expansion and the Rise of the Necromancer content pack into a single comprehensive edition. Players engage in combat against demonic enemies across the series' signature hack-and-slash gameplay, carrying forward a franchise lineage that spans multiple console generations. The inclusion of Reaper of Souls and the Necromancer pack means the collection represents a complete version of the third mainline entry in the long-running Diablo series, incorporating all major post-launch content released up to that point. The Nintendo Switch version notably made the title portable for the first time in the series' history.
