Thornguard

A tower defense roguelike — fulfill prophecies, earn titles, master the elements

Coming Soon to iOS, macOS, and Android

Thornguard is a retro tower defense roguelike with more depth than pixels. Build elemental towers, draft abilities, collect relics, and fight your way through prophecy-themed challenge tracks. Each run is different. Each death is educational.

Fulfill Prophecies, Earn Titles

Choose from 9 prophecy tracks before each run. Four elemental prophecies pit you against themed enemy waves. Four tactical prophecies test specific strategies. One throws everything at you from wave one.

Each prophecy has 6 difficulty levels with signature mechanics that intensify as you climb. Beat a level, earn a title. Work your way from Ember Watcher to Siegebreaker, from Frost Initiate to Glacial Sovereign.
