About This Game

About the demo

This demo offers a glimpse of the full game. Some features are locked or limited, including game modes, the shop, archetypes, mutators, and challenges.

Become a necromancer who raises the freshly fallen to forge a living army.

Real-time combat, active pause, evolving spells, modular allied AI, and adaptive threats — Undying One is a tactical ARPG focused on commanding your summons… and surviving your own choices.

Raise your enemies. Command an army.

Every defeated foe can be turned into a summon — tank, mage, support, or DPS.

Their stats, spells, and behaviors are preserved and grow alongside you.

A Dynamic AI System

Your summons choose their targets, spells, and priorities based on:

• threat level

• distance

• enemy weaknesses

• their assigned role

• randomly selected tactical behaviors

No two fights ever play out the same.

A Tactical ARPG with Active Pause

Use the pause to:

• reorganize your summons

• precisely target enemies or allies

• cast the right spell at the right moment

• analyze current buffs and debuffs

When time flows again, every decision matters.

Progression Through Use

Spells and summons grow naturally:

• cast a spell → it becomes stronger

• keep a summon alive → it gains tiers

Side effect: spells become more expensive.

Mana is a constant source of pressure.

Unlockable Mutators & Difficulty

Customize your runs with modifiers such as:

• random starting spells

• reduced maximum mana

• increased vulnerability

• support spells disabled

• unstable corpses

Each mutator has its own unlock condition.

Between-Run Shop

Spend in-game currency to unlock:

• permanent upgrades

• new spells

• stat bonuses

• archetypes

A Demanding Roguelite Loop

Enemies grow stronger with each wave.

Your resources dwindle.

Your summons fall — and must be replaced.

Defeat is never far away…
but every run leaves you stronger.
