Pokémon Cinnabar Sword and Cerulean Shield are romhacks of Pokémon Sword and Shield which change every Pokémon’s shiny palette, raise the difficulty, add Shadow Pokémon and change the shiny odds to 1/100.

Shadow Pokémon, much like Delta Pokémon, are species with their type, visual appearance and moveset altered.

The game also features pre-randomized wild encounters for all zones, including the DLC.
