Game Overview
CODEX MORTIS is a necromantic survival bullet hell where you harness forbidden death magic to battle relentless armies of the undead. Command your minions, forge devastating spell combinations, and fight alongside powerful heroes—either solo or in local co-op—as you pursue ultimate power. Before each mission, meticulously plan your strategy by assembling and equipping your death squad for annihilation. Customize your necromancer with dozens of unique skills drawn from five distinct schools of dark magic, allowing for intricate synergies and builds that turn the battlefield into a canvas of chaotic destruction. Once the mission begins, unleash your carefully crafted arsenal: detonate corpses, command undead legions, and sacrifice blood to trigger apocalyptic explosions. The more spells you combine, the more spectacular the devastation. Mix and match powers from Necromancy, Summoning, Blood Magic, Soul Magic, and Curses to create powerful effects like burning explosions or terrorized enemies trapped by undead forces. Explore eight procedurally generated levels, each offering opportunities to experiment with infinite build variations. Command heroes with unique abilities, equip artifacts for powerful bonuses, and upgrade your skills to enhance damage, cooldowns, health, and speed, ensuring every run is a fresh and thrilling challenge.
