About

As a fellow gaming enthusiast, let me share with you an exciting cooperative multiplayer game I recently discovered – it’s called NAMAKORIUM. In this chaotic real-time strategy, you and three friends can join forces to command a unique team of “sea cleaners,” or Namakos (sea cucumbers), left behind by humanity. Our mission? To dive deep into the polluted oceans and restore them to their former glory! It’s an engaging experience that combines strategy, teamwork, and the chance to make a difference in our virtual underwater world. Give it a try, and let’s clean up those oceans together!

Could you revive the enchanting ocean? Your strategic planning, help from your friends, and loyal sea cucumbers are crucial. Prepare for an exhilarating, fast-paced marine debris cleanup mission!

Organize Your Namako Operation

Gather and clean up all available resources, build structures, and unblock obstacles – there’s a lot to do and we need to act quickly! (In this context, Namakos refers to individuals or entities responsible for tasks in a game or project.)

Will your strategy hold up under pressure and succeed with the team?

Unique Namakos with Special Traits

The creature named Shell Namako specializes in collecting limestone. Iron Namako stands out for its exceptional mining skills. Meanwhile, both Flame Namako and Ice Namako are remarkable for their ability to endure severe temperature extremes.

Use their distinct abilities to assign roles and conquer each stage together!

Restore the Ocean’s Beauty

As you decontaminate, corals bloom, sunlight shines through, and the ocean regains vibrant color.

40 distinct “Sea Wonders” are set to grace the waters – can you gather them all while restoring the oceans’ health?

Beware the “Blight Namako”!

During cleanup, corrupted Namako known as “Blight Namako” may suddenly appear.

They rot your food and drag the ocean back into darkness.

Team up and repel them with the mighty Namako Fusion Cannon!
