Korean outlet MTN reports that the game, known as Project H/Skyline internally, has been canceled following a round of layoffs in October last year. That's not the only affected game, as another title codenamed Project Pantera, based on NCSoft's Lineage franchise, has also been canceled.

Sony reportedly shelves yet another one of its live-service games, marking its 11th such project cancellation in only three years.

Last week, PlayStation reportedly canceled a live-service God of War game from Demon's Souls remake studio Bluepoint and cut a live service game from Bend Studios, the Days Gone developer. It's now been reported by MTN that some of NCSoft's games have been canceled, too, and ResetEra users believe one of the culled projects is the Horizon MMO.

An unannounced MMO based on PlayStation's Horizon series has reportedly been cancelled, with this being one that was in the works at South Korean publisher NCSoft.
