About the Game
Rubinite is an extremely challenging boss rush action game set in a dark fairy tale world.
The key to combat is one distinctive core mechanic: Focus. Use Focus to read an enemy,
expose its weak point, and land a lethal strike.
You play as Ruby, a princess on a journey of revenge to reclaim her home: The Scarlet Kingdom.
Fight the Bloodstained to the Death
Ruby’s blade alone will barely wound them. Find their weak points,
drive the lethal strike home, and make it out alive.
Your Bloodline: Both a Blessing and a Curse
To take back the Scarlet Kingdom, Ruby must face the Bloodstained in every form they take,
whether it be an ancient secret cult, undying parasites, or the source of a deadly plague.
Grip your blade and challenge foes that grow deadlier with every step.
Exquisite Pixel Environments
Step into beautifully crafted pixelated scenes, where the poignancy and grandeur of the Scarlet Kingdom come alive in every hazardous battle.
Absorb Pureblood, Forge Talismans
Every Bloodstained you kill surrenders its power.
Absorb it to grow stronger for the fight ahead, craft a wide range of Talismans,
and build a combat style that's entirely your own.
