Polyscape's NAMAKORIUM, a game about commanding sea cucumbers to decontaminate the ocean, left early access on May 19 with a major update and a 40% discount. The full version adds a boss called Magatsukegaregami that preys on sea cucumbers and can only be damaged by cleansing the pollution it is fused with. Coral grows as decontamination progresses, giving sea cucumbers places to hide from the boss's line of sight. Five new stages join the roster, including one where players drive a decontamination sea cucumber car and another with seven Blessing Lighthouses that boost sea cucumber speed. Two stages previously exclusive to the Sea Cucumber Leader Contest event are now permanently available, bringing the total to 16 stages. Three costume DLC sets are also on sale, each containing five skins for 500 yen, plus a free Supporter Pack with a cucumber costume. The game is participating in the Steam Ocean Festival 2026 from May 19 to May 26.
