Summum Aeterna, a Roguelite game, pioneers novel world-crawling mechanics within the genre. It marries brisk combat with a distinct 2D art style. Assume the role of the immortal King of Darkness, a formidable and relentless warlord, eternally cursed. Traverse uncharted realms teeming with treasures, hazards, hordes of adversaries, and formidable bosses.

Venture into untamed domains, plumb the perilous depths of Aeterna, and battle your way to each world’s conclusion… If you can!

Summum Aeterna


Although the King of Darkness may be invincible, he is not invulnerable. In this genre, you restart your journey repeatedly, right? Don’t fret; even in defeat, you retain some acquired gear and upgrades from your previous life… Well, some of them, at least.

Summum Aeterna ensures persistent progression, featuring an enduring character and world-enhancement system. Regardless of how often you fall, your advancement in the skill tree endures, along with the lasting effects of world enhancements you’ve unlocked.

Summum Aeterna


Summum Aeterna introduces an unprecedented world-generation system: the Seed Mechanic. Each seed births a one-of-a-kind world with distinct enemy behaviors, special events, and variable map sizes, contingent on the seed’s rarity and genetic composition.

These “seed genes,” or world modifiers, wield both beneficial and detrimental attributes. They dictate the perils, encounters, and rewards that await as you embark on your journey. You can generate a world that complements your playstyle perfectly. Seeds construct worlds, and genes differentiate each seed from the last, producing distinct worlds each time!

Summum Aeterna


Survival in Summum Aeterna hinges on eliminating every living (or undead) entity you cross paths with. How is this accomplished? Well, you play as a cursed monarch… and your armaments are fit for royalty! Show no mercy; utilize swords, pistols, and scythes to compel them to plead for their wretched lives before they can do the same to you.

While you choose a starting weapon at the outset of each world, you have the liberty to exchange it for a superior one, regardless of its type… It’s your choice, driven by your skill! Summum Aeterna also incorporates weapon personalization through gems—precious stones that heighten weapon attributes and introduce impressive enhancements. By embedding gems, you can append new offensive and passive capabilities, enhancing your weapon’s combat prowess. Furthermore, by collecting specific diagrams, you can elevate your weapons to the Summum level, unleashing their true potential!

Summum Aeterna


In Summum Aeterna, you craft your odyssey. Each world bestows numerous rewards, including fresh seeds and currencies for enhancing character skills, unlocking new weapons, and refining existing ones to lethal precision.

Moreover, you can expand your horizons by accessing special chambers, enhancing item rarity, and manipulating world conditions via the world upgrade menu. You even have the option to mutate gene sequences to alter seed rarity or recycle unwanted ones to obtain seeds of higher rarity…

Summum Aeterna


Summum Aeterna introduces an engaging multiplayer and cross-platform feature—the “Board of Champions.” This mechanic tracks the highest-level seed completed in the shortest time by every contender. There are leaderboards for influenced seeds and standard seeds.

The top 3 qualifiers will earn gold, silver, or bronze crowns that adorn His Highness in-game, irrespective of the player’s appearance, as long as they remain on the podium. Do you desire to see your King of Darkness crowned in the manner befitting a monarch?
