World Tree Defender - Seedlings of Yggdrasil
SteamAbout World Tree Defender - Seedlings of Yggdrasil
A hex-grid tower defense adventure where you shape the battlefield, grow a living World Tree, and unleash elemental combos against relentless enemies.
About the Game
World Tree Defender is a strategic tower defense built on hex grids, elemental synergies, and real-time spellcasting. Choose your heroes, build your towers, and cast powerful spells to defend the World Tree against waves of relentless enemies.
Explore three distinct biomes — each with its own strategic opportunities and dangerous weather effects — while collecting soul relics that unlock deep build customization and new abilities.
Every run is a fresh puzzle: terrain shapes your towers, weather twists your plans, and the relics you equip decide whether you chase raw power or build an unshakeable foundation.

Magma Surge
Miremaw — Swamp
A treacherous marshland where fog obscures the battlefield. Winding waterways slow enemy advances while the murky depths hide dangers — and opportunities — for cunning defenders.
