To celebrate the release of the brand-new hololive GoroGoro Mountain,

a special 2-title bundle is now available:

hololive Treasure & GoroGoro Double Pack!

▶ View the bundle page here

Even if you already own hololive Treasure Mountain,

you can get hololive GoroGoro Mountain at 10% off with this bundle!

This cheerful and colorful 3D action game is inspired by hololive’s beloved VTuber, Houshou Marine!

Take on the role of one of her loyal pirate crew members,

and roll hololive talents—yes, the “treasures” gathered by Captain Marine—

up a mountain, merging identical ones together to grow them as you climb!

Sometimes they’ll roll too far, or bounce off in unexpected directions…

but that’s all part of the chaotic and heartwarming joy of this fan-filled journey!

With two very different “mountain” experiences,

now’s the perfect time to enjoy both titles!
