The Core of Pluto is a biome found deep into the grounds of Pluto. It hosts different enemies, ores, and a poisonous gas that the player will need a Gas Mask to explore through (the gas creates a purple effect on the background). The Core is made out of mostly Plutrite Ore , an ore used to make Plutritium Bars. There will pools of Pluliquid, as well as tunnels that lead back upground to the Shrines of Chiron.
