About this game

🏰 Defender of the Realm — An Indie Wave-Based Survival Adventure Game

Defensor del Reyno is an indie wave-based defense game with exploration, resource gathering, and narrative progression. You control the Defender of the Realm, a warrior who must protect the castle as the world cycles thru two seasons—autumn and winter—with day-and-night cycles that change the difficulty and atmosphere.

As the enemy’s creatures advance and winter grows harsher, you will rely on your skill, your strategy, and your allies: Elara (half-human, half-vampire) and Teryn, the castle builder.

Each map is set in a different combination of day/night and autumn/winter, affecting the chapter’s resources, enemies, and challenges.
