NO PAUSES. ONLY SLAUGHTER.
The abyss doesn't wait for you to open a skill tree.
SACRIFICE your hard-earned Gems at Altars scattered throughout the arena to evolve your weapon.
Empower your arsenal on the fly, adapt in the middle of a firefight, and never break your momentum.
The action only stops when you die.

ONE WEAPON. INFINITE CHAOS.
Start with a hand(gun).
End with an arena-clearing instrument of godlike destruction.
EVOLVE your weapon by unlocking distinct upgrade paths at forgotten Altars.
Stack powerful synergies, experiment with countless combinations, and craft absurd, game-breaking builds that carry you through your entire run.

HUNT OR BE HUNTED
Master fluid, high-mobility FPS combat against overwhelming odds.
Every kill matters. Tear through relentless swarms of monsters and harvest the Gems they leave behind.
Every kill fuels your evolutions, and your evolutions are the only thing keeping you alive.

ENTER THE TRIAL
Every layer demands a different strategy.
Defend ancient Altars, survive impossible waves, or complete unique objectives to unlock the path forward.
The rules change. The arenas shift. The hordes grow more vicious.
Adapt your build or be buried.

DESCEND DEEPER
Complete the Trial and descend into the next layer.
Nine Descents stand between you and the bottom of an endless hell.
Each layer introduces deadlier enemies, new hazards, unique Trials, and colossal boss encounters.
Push deeper, uncover hidden shrines, and let a real-time composed orchestral soundtrack score your rampage.
