NAMAKORIUM is a chaotic, cooperative multiplayer RTS for up to four players.
Command the "sea cleaners"—Namakos (sea cucumbers) left behind by humanity—and clean up the polluted oceans!
Plus, Solo Mode lets you choose your style: take it slow and chill, or push for peak efficiency!
Can you reclaim the beautiful sea?
It’s all up to your planning skills, your friends, and your trusty sea cucumbers.
Get ready for a frantic, action-packed ocean cleanup operation!
Command unique Namakos, gather resources, construct buildings, and clear paths—the tasks are many and time is short.
Purify all the pollution before the food runs out!
Will your strategy hold up under pressure and succeed with the team?
Shell Namako gathers limestone. Iron Namako is great at mining. Flame Namako and Ice Namako can survive extreme temperatures.
Use their distinct abilities to assign roles and conquer each stage together!
As you decontaminate, corals bloom, sunlight shines through, and the ocean regains vibrant color.
Over 50 types of "Scenic Creatures" will begin to swim in—try to collect them all as you heal the seas!
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!
Play your way—not just in multiplayer, but solo too!
All stages have been fine-tuned for solo play.
Perfect your strategy and aim for the best time!
Of course, taking it slow and steady is perfectly fine too!
Planning x RTS Gameplay: Strategize based on map structure and control multiple cucumbers simultaneously
Chaotic Cooperative Play: Plans may succeed... or hilariously fail—every match brings its own story
