CODEX MORTIS Demo
About this game
Codex Mortis is a necromantic survival bullet hell where you wield the forbidden powers of death against an endless tide of the undead. Command armies, forge devastating spell combinations, and fight alongside powerful heroes—solo or in local co-op—in your quest for ultimate power.

Plan before you slaughter. Assemble your death squad and equip them for annihilation—before the mission begins. Craft your necromancer from dozens of unique skills across five schools of dark magic, theory-craft lethal synergies, and design builds that will paint the battlefield with chaos.
Once the mission starts, watch your masterpiece unfold: detonate corpses, command undead armies, sacrifice blood for apocalyptic explosions. The more you combine, the more beautiful the DESTRUCTION.


Collect 5 ancient pages and defeat the portal guardian before the immortal Lothar hunts you down.
Preform powerful rituals to strengthen your necromancer, battle guardians protecting cursed artifacts, and claim urns containing the souls of fallen heroes.
Mix spells across five schools of dark magic—Necromancy, Summoning, Blood Magic, Soul Magic, and Curses—to create explosive combinations.
