Bethesda today reversed its earlier cancellation of mod support for PlayStation 4 versions of Fallout 4 and Skyrim Special Edition - with one major restriction.

Though broadly speaking mods will be supported on the Sony console, mods that utilise external assets will not.

That restriction eliminates the possibility of new textures, models, or sound files being imported into the games, meaning only content included with the initial release can be used in mods - no Thomas the Tank Engine or Macho Man Randy Savage mods allowed.

"We and Sony have worked hard to make this possible," wrote Bethesda on its blog.

Fallout 4's other platforms feature full mod support, with external assets, though Xbox One mods have a file size limit imposed upon them.

Previously, Bethesda had stated that mods would not be coming to PS4 versions of the games at all, citing a refusal on Sony's part to "approve user mods the way they should work."

In addition to mod support, Bethesda also announced that Fallout 4 and Skyrim will both receive native 4K support and "enhanced lighting and graphics features" on PS4 Pro.

Mod and 4K support will reach Skyrim first, before being patched into Fallout 4.

Skyrim Special Edition launches October 28th on PS4 and Xbox One, and can be pre-ordered at Mighty Ape.
