Defend Thy Realm Against the Horde.
Defense of Kyrath is a lighthearted fantasy tower defense game set in a thousand-year-old realm besieged by a relentless horde. Place wardens, marshal archers, and hold the line across a compass-rose campaign spanning five hand-crafted biomes. Builds to a 20-tier roguelike ascent mode called The Folly.
The horde is coming. Position your wardens, marshal your archers, and hold the line across whimsical levels of fantasy defense. Kyrath will not fall.
Defense of Kyrath combines strategic tower placement with RPG-like progression in a charming Olde English fantasy world. Choose from nine unique warden types — from the swift Sylvan archers to the chilling Frostfang serpents — and face eighteen enemy types with distinct resistances and weaknesses. Enemies fight back: Bog Matrons web your wardens, Hedge Witches poison them, Champions slam them with crippling afflictions.
Progress through seventeen levels across five biomes, earn tokens to unlock new wardens, invest in a 29-talent tree, and tackle brutal edict modifiers. Then ascend The Folly — a 20-tier roguelike ascent mode with boon choices, milestone challenges, and earned titles.
