Rubinite Beginner Guide - What a Full Walkthrough Covers

Rubinite is an extremely challenging boss rush action game from Cup Dog Games, released on Steam on Jul 22, 2026 at $15.99 in the US. The whole loop rests on one mechanic named in the store text, Focus, and the listing is explicit that Ruby's blade alone barely wounds the enemies she faces.

What the store text sets up

You play as Ruby, a princess on a journey of revenge to reclaim her home, the Scarlet Kingdom. The store text describes a dark fairy tale world and promises pixel environments that carry the "poignancy and grandeur" of the kingdom through every battle.

The adversaries are the Bloodstained, and the listing says they appear in several forms: an ancient secret cult, undying parasites, and the source of a deadly plague. That is the entire official description of the cast, and no bestiary is published.

The Focus loop in the listing's own words

The store text reduces combat to three steps: use Focus to read an enemy, expose its weak point, and land a lethal strike. It also states plainly that the blade alone will barely wound them, which makes the weak-point window the actual damage source rather than a bonus.

Listing step	What the store text says
Read	Use Focus to read an enemy
Expose	Find and expose its weak point
Strike	Drive the lethal strike home and make it out alive
Escalate	Foes grow deadlier with every step

No stamina system, parry window or combo list is published, so no timing data can be quoted here.

Pureblood, Talismans and building a style

Progress is built on what you take from enemies. The store text says every Bloodstained killed surrenders its power, which Ruby absorbs as Pureblood to grow stronger for the fight ahead.

That resource is spent on Talismans, and the listing promises a wide range of them for building a combat style that is entirely your own. It publishes no Talisman list, no rarity ladder and no upgrade costs, so a full walkthrough of the build system cannot be assembled from official material.

Difficulty and the boss ladder

Ten of the game's achievement names published by the API read as boss defeats, and each records a distinct fight. The store text frames the whole game as extremely challenging, and it repeats that enemies grow deadlier with every step.

• Defeated the Beast, and repelled the Guardian.
• Defeated the Gravekeeper, the Plaguebearer and the Dual Cultists.
• Defeated the Martyred Angel, Faye and the Ghost.
• Defeated Roy and the Puppet Master.

Those names are the only boss roster the official data exposes, and 38 achievements are listed in total.

Price, platforms and what is not published

At capture the US price was $15.99, 20% off the $19.99 list price. The listing covers Windows and macOS, supports eight languages with no full audio flag, and carries no Steam content descriptors, though three regional schemes rate it for violence.

The store page publishes no boss order, no map of the Scarlet Kingdom, no playtime estimate and no full walkthrough. One additional app, 4854050, appears alongside the base game.
