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.
