Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Mithril & Mud is a content-rich incremental/idle game with deep interlocking systems. Early Access lets me gather player feedback on pacing, balance, and progression — things that are nearly impossible to tune in isolation. Input directly shapes the game. Balancing and End Game aspects are top priority. ”

Approximately how long will this game be in Early Access?

“Estimated 3-6 months, depending on player feedback and the scope of changes needed. This needs to be early access due to the intense balancing feedback needed with the major variety of ways a play can progress. ”

How is the full version planned to differ from the Early Access version?

“We plan to significantly expand the endgame experience beyond Depth 20. Currently, post-victory play relies on numerical scaling, and we want to change that by introducing new rooms, mechanics, and meaningful content that unlock at deeper depths. We plan to rework the challenge system with engaging modifiers and unique rewards, add new prestige and ascension perks to deepen the meta-progression loop, and expand mythic upgrade paths so veteran players have fresh goals to pursue rather than simply pushing numbers higher.

We plan to make key moments in the game feel more impactful. This includes an interactive victory event at Depth 20 that gives players a memorable, playable experience rather than just a summary screen. We also plan to introduce new boss encounters and story-driven events at milestone depths, as well as expand the existing troll and Lithodore encounters with new mechanics as players push deeper.

We plan to use Early Access feedback to guide a thorough economy and balance pass, including shadowsteel tuning, quest reward scaling, and endgame cost curves. Quality-of-life improvements and additional automation options will be shaped directly by what the community asks for. We also plan to upgrade the visual presentation of the central mine area, add additional music and sound design, continue refining localization across all 10 supported languages, and explore bringing the game to the Steam Deck.”

What is the current state of the Early Access version?

“The game is fully playable from start to depth 20, with 12 mine rooms, prestige, ascension, a skill tree, trade systems, expeditions, daily quests, achievements, and Steam Cloud saves. All core systems are complete and stable. ”

Will the game be priced differently during and after Early Access?

“The game will be available at a lower price during Early Access. The price will increase at full release to reflect the additional content and polish added during the Early Access period. If you buy during Early Access, you keep the game at the lower price. ”

How are you planning on involving the Community in your development process?

“Player feedback is central to development. A Steam Community discussion board will be active for bug reports, feature suggestions, and balance feedback. Updates will be posted regularly with patch notes detailing what changed and why. Balance adjustments to depth scaling, resource pacing, and progression systems will be driven directly by player experience and feedback. ”

About This Game

Dig deep. Build big. Grow endlessly.

Mithril & Mud is a dwarven mining incremental game where every swing of the pickaxe brings you closer to the riches buried below. Start with nothing but stone and ambition — end with a sprawling underground empire fueled by mithril, shadowsteel, and ancient rune magic.

Mine the Depths

Descend through 20 increasingly dangerous depths, each unlocking new rooms, resources, and challenges. Cave-ins and trolls threaten your progress — but the deeper you go, the greater the rewards.

Build Your Hold

Construct and upgrade 12 specialized rooms — from Smelters and Lumber Mills to Runic Workshops and the Dark Forge. Assign your dwarven workers, optimize production chains, and watch your underground kingdom come to life.

Automate Everything

Unlock auto-miners, auto-workers, and multi-room assignment systems that keep your hold running while you're away. Come back to mountains of resources waiting for you.

Prestige and Ascend

Reach the bottom? Start again — stronger. Prestige grants Ancestral Knowledge and Blessings that carry forward. Ascension opens an entirely new layer of progression for those who want to go even deeper.

Master the Systems

  • Skill trees, artifacts, gems, and runestones

  • Trade with foreign nations across infinite tiers

  • Send caravans on timed trade missions

  • Hire warriors and protect against cave-ins

  • Complete daily quests, challenges, and expeditions

  • Tame beasts for powerful passive abilities

  • Mythic upgrades for endgame power spikes

Handcrafted Feel

Every sound and visual is procedurally generated — from the crunch of the pickaxe to the warm glow of the forge. No stock assets (yet), just a world that feels uniquely alive.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Mithril & Mud uses AI-assisted development tools during the programming process. All game design, systems, and content decisions are made by the developer. No AI-generated content is presented to players during gameplay — all visuals and audio are created through procedural generation algorithms, not generative AI.
