About this game
In Iron Decree, you play as a Paladin either solo or as a team of 4, pitted against the hordes of a necromantic cult; you are tasked with defending various fortresses in a grand fantasy war. Arm yourself with spells, build wards to repel evil, and fight to the bitter end.
UNLEASH ARCANE FURY
Experience relentless action inspired by '90s shooters, round based zombie survival games, and dungeon-crawling classics. Wield magic and melee together, chaining devastating combos to crush your enemies. Unlock potions, spells, and enchanted weapons mid-run, and drink mystical brews to unleash powerful bonuses that turn the tide of battle.
FIGHT THE IMPERIUM
Explore a grimdark fantasy world, uncover hidden secrets, and protect the derelict fortresses of a crumbling empire. A brutal war rages between an insurgency and radical Imperium necromancers who wield forbidden magicks for profit. Choose your path: purge the heretics or uncover the dark truth behind the endless conflict. Defend mystical gravesites, enchanted libraries, sacrificial chapels, and more as you fight to decide the fate of the realm.
FORGE YOUR LEGEND
Upgrade your character and arsenal as you survive each round. Unlock a huge arsenal of weapons, master unique spells, and discover powerful enchantments, potions, and treasures. Mix and match different effects to craft deadly combos and tailor your build to your specific playstyle.
INCLUDES LEVEL EDITOR AND WORKSHOP SUPPORT!
Create your own maps, with inbuilt support for custom levels created in the game itself, or explore user created maps on the workshop.
