Core Keeper Takes to the Waves with ‘The Sunken Sea’ Content Update, Launching June 15


LONDON, UK – June 12, 2022 – Head out on a seafaring adventure and discover uncharted islands in Core Keeper's 'The Sunken Sea' update, the first major content update for the hit 1-8 player mining sandbox adventure, launching this Wednesday, June 15.

Available as a free update to all Core Keeper players, 'The Sunken Sea' will introduce a brand-new water-based biome filled with large, mysterious bodies of water to explore and islands to uncover. Take to the seas in boats and discover a colourful new ore, Octarine, on your adventure to defeat Omoroth the Sea Titan, a brand-new titan boss lurking beneath the ocean waves.

Encounter new aquatic enemies and a new sub-boss, Morpha the Aquatic Mass, while discovering new locations, fish, plants, food types and more. Equip your explorer with new weapons and gear, including new Octarine Armour and the Bubble Gun, a new bubble-blowing ranged weapon.

Multiple new base-building items will also give explorers more equipment than ever to build their ultimate homestead, including sprinklers to keep crops watered automatically; portals that can be used to warp instantly between different areas of their worlds; and new workbenches to craft multiple new items, including a new Fishing Bait Workbench and Jewellery Workbench. Many more quality-of-life improvements and game-balancing tweaks will also be introduced with the update.


"We've worked really hard to deliver an expansive and meaningful line-up of new content for Core Keeper players to discover with The Sunken Sea update," said Sven Thole, CEO & Animator at Pugstorm. "We are listening closely to suggestions and feedback from our community and we are very excited for players to discover everything The Sunken Sea has to offer when it rolls out later this week."
