NAMAKORIUM (ナマコリウム) is a premium simulation game that takes you into an underwater world that has sadly been neglected by humans. In this game, you take control of Namakos — hardworking sea cucumbers known as nature’s cleaners — tasked with slowly restoring the ocean’s lost beauty.

At first glance, NAMAKORIUM (ナマコリウム) feels calm and charming, with soft colors and a soothing underwater atmosphere. Don’t let that fool you, though. Beneath that relaxed surface is a surprisingly deep and demanding experience that requires planning, teamwork, and smart decision-making to truly bring the ocean back to life.

Frantic underwater experience

NAMAKORIUM (ナマコリウム) is a multiplayer-focused experience where up to four players work together in a cleanup operation. You’ll clean polluted areas, gather materials, clear blocked paths, and build structures. Teamwork is crucial because each player controls a different Namako type with a specific role. For example, Shell Namako can gather limestone, while Flame Namako is built to withstand extreme heat.

Let the ocean transform from dim and contaminated into vibrant, crystal-clear waters. As you progress, corals will bloom again, and different sea creatures will return to swim freely. You can collect over 50 Scenic Creatures, mixing real and fictional species. Along the way, however, you will encounter Blight Namako — a corrupted sea cucumber enemy that spreads pollution and works directly against your goal.

There are upgrades to unlock that open new paths and abilities, giving players more ways to solve problems and handle challenges. While the game is charming and strategic, it shines brightest in multiplayer. When fewer players are online, matchmaking can take longer, which may feel frustrating if you have no one to play with. Some players might find the solo experience less engaging.

Relaxing yet surprisingly complex

Overall, NAMAKORIUM (ナマコリウム) stands out as a unique multiplayer strategy game set in a calming yet challenging underwater world. Restoring polluted seas with other players is fun despite being chaotic most of the time. While the experience is best enjoyed with friends and can feel less appealing when played solo, watching the ocean slowly return to life makes each successful run feel worthwhile and satisfying.
