Sanctum: Abbey Defense

Sanctum is a calm-strategy tower defense: half monastery builder, half drone siege. Grow a small abbey into a fortified sanctuary. Every monk has a job — hauling ore, baking food, standing watch — and every room you build changes what your monastery can survive. Then the drones come. BUILD A LIVING ABBEY Lay out cloisters, granaries, and dormitories to grow your population. Every monk you raise can be assigned to build, farm, defend, or study — reassign them on the fly as each wave demands something different from your walls. THREE WAYS TO FIGHT BACK • Wardens — fast, close-range defenders for the walls • Trebuchets — slow siege weapons that crack armored Ironclads • Culverins — long-range marksmen that see through cloaked Phantoms FACE A GROWING SWARM Common drones give way to armored Ironclads, cloaked Phantoms, and the towering Harbinger — a boss that bursts into a swarm of smaller drones when it falls. Twenty-five waves stand between your abbey and peace. EVERY RUN MATTERS, WIN OR LOSE The Illuminated Codex permanently grows stronger the more you play — extra monks, deeper stores, sharper weapons — unlocked by shards earned from every run, victory or defeat. Rare reliquary caches offer a choice of lasting boons mid-run. A new blessing greets you every day, and a rotating weekly trial reshapes the rules for those chasing a real challenge. THREE TRIALS OF FAITH Pilgrimage, Crusade, and Tribulation offer a measured path, a fiercer fight, and a true furnace of faith for veterans. Built for landscape play, calm pacing, and the satisfaction of a wall that holds.
