About the Game

Codex Mortis is a necromantic survival bullet hell where you wield the forbidden powers of death against an armies of the undeads. Command minions, forge devastating spell combinations, and fight alongside powerful heroes—solo or in local coop—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.

DEVASTATING SPELL SYNERGIES

Mix and match spells across 5 schools of dark magic:

  • Necromancy - Bone spears, corpse explosions, skeletal prisons

  • Summoning - Raise undead armies and bone golems

  • Blood Magic - Sacrifice life for devastating power

  • Soul Magic - Harvest essence, phase through enemies

  • Curses - Break enemy will, spread terror and confusion

Combine spells for devastating effects. Blood Magic + Necromancy = burning explosions. Curses + Summoning = terrorized enemies trapped by undead legions.
