Overview

Quartermark is an indie RPG from ACA Games that flips the usual combat loop on its head. There is no attack button.

Your four heroes fight automatically, and your job is to make sure they win by deciding who stands in the party, what they wear, and which skills you feed them. It's a strategy-heavy, inventory-driven experience that blends auto-battler mechanics with dungeon crawling and idle-style progression.

Released on October 19, 2026, the game is currently available on Steam with a discount, and it supports a wide range of languages including English, Japanese, Traditional and Simplified Chinese, Korean, and many European languages. It's a single-player title with Steam Achievements, and it can be played with mouse only, making it easy to jump into.

Highlights

  • No Attack Button: Combat is fully automated. Your heroes fight on their own across 100 maps and 3,400 floors, and your strategic choices determine the outcome.
  • 440 Hand-Built Monsters: Every creature is a unique 3D model with its own skeleton and animations. From a rotting stag to a dragon on its eggs, each monster breathes, strikes, and flinches in its own way.
  • Deep Party Management: You control the party composition, equipment, and skill loadout. Adjusting these is the core of the game, and it's what lets you overcome bosses that wiped you out earlier.

Who It's For

If you enjoy auto-battlers, idle games, or party-based RPGs where preparation matters more than reflexes, Quartermark is worth a look. The emphasis on inventory management and loot means there's plenty of theorycrafting for players who like to optimize.

It's also a good fit for those who prefer a more relaxed, at-your-own-pace experience, since the game is explicitly playable at your own pace.
