Build a defense. Command a Hero. Keep the castle standing.
Hillfort is a tower defense game with a complete 12-mission campaign you can play free, including offline solo play. Position your towers, choose their targets, and move your Hero to stop enemies before they reach the Keep.
SIX STARTING TOWER FAMILIES. DIFFERENT JOBS.
Use fast Bolt shots against single targets, Cannon blasts against crowds, Frost to slow the advance, Arc lightning to chain through enemies, Sky darts against flyers, and Rail shots to pierce the line. Unlock the Storm Spire with earned Crystals to push ground crowds back. Placement, range, and timing matter.
TRAIN THE TOWERS YOU USE
Earn tower mastery in battle. Explore connected talents, compare two combat specializations for each tower, and preview visual changes before choosing. Earn the requirements and resources for new forms through play.
YOUR HERO IS PART OF THE DEFENSE
Choose a starter Hero, move across the battlefield, and activate that Hero's abilities. Earn experience and unlock combat forms that answer different enemy threats.
MORE REASONS TO RETURN
Replay for three stars, tackle Veteran difficulty, test your defense in Endless runs, and unlock Daily Challenges as your Keep grows. Battles develop your Keep, towers, and Heroes and award earned Crystals for in-game unlocks. Play at normal or double speed. No energy meter limits your next attempt.
MORE BATTLES
The optional Ashfall Chronicle adds 24 campaign missions—Missions 13–36 across four additional regions—and three Ashfall story battles. Your original 12 missions stay free.
Ashfall is a one-time, non-consumable purchase with no scheduled expiration, trial, or subscription. It buys additional play, not currency, retries, or combat-power boosts. Apple shows the localized price before confirmation. Restore Purchase is available for an eligible existing purchase.
No ads. No loot boxes. No Hillfort account required.
