Undying One
SteamAbout 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.

For you, it is only the beginning.
In Undying One, you play as a necromancer who turns fallen enemies into loyal servants. Every battle strengthens your army as you expand your control over the dead.
Fight in real-time with active pause, command your minions, and shape your playstyle through spell mastery and undead specialization.

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.
Your army is your greatest weapon.

Your summons choose their targets, spells, and priorities based on:
No two fights ever play out the same.

Battles are fast and chaotic, but you are never without control.
Switch seamlessly between strategic control and real-time action.
Spells and summons grow naturally:

Mana is a constant source of pressure.
Customize your runs with modifiers such as:
Each mutator has its own unlock condition and increase the run's rewards.
