The Duke Nukem compilation, Duke Nukem 3D: Megaton Edition, was released late yesterday and is available now for download on PlayStation 3 and the PS Vita, according to the PlayStation Blog. The title is available free for PlayStation Plus members as part of Sony's monthly offering.
The Megaton Edition, published by Devolver Digital, includes Duke Nukem 3D: Atomic Edition, Duke Nukem Caribbean: Life's a Beach, Duke It Out in D.C., and Duke: Nuclear Winter. The Atomic Edition alone includes all four episodes in a "visually restored format."
Outside of PlayStation Plus membership, the game is regularly priced at $9.99 on both platforms.
