Royal Frontier is a tactical fortress-defense strategy game. By day, collect gold, choose building sites, and construct watchtowers, bombards, barracks, frost spires, gates, and mills. By night, command the king, support your defenders with Mighty Cry, and repel increasingly dangerous waves.
Liberate six distinct lands, survive five nights in each, and face the Eclipse Lord. Campaign blessings shape your strategy by strengthening the king, fortress, towers, economy, or special ability. Defeating the final boss unlocks Endless Defense: enemies grow stronger every wave, a boss returns every fifth round, and your best result is saved.
How to play
During the day, approach a glowing building site to construct or upgrade a structure. On PC, use WASD or the arrow keys to move, Shift to sprint, E to build, keys 1–6 to choose a building, Space to use Mighty Cry, and the mouse wheel to zoom. On mobile, move with the left joystick; sprint and build controls are on the right, while the ability button is beside the king's health.
When your defenses are ready, press Start Night. Protect the fortress, collect dropped coins, and support your towers with the king. If the king loses all health, he is temporarily knocked out; if the fortress is destroyed, the night is lost. Survive five nights to unlock the next land. Defeat the final boss to open Endless Defense.
