More about this game

Defend your castle wall from an endless siege. You must build and upgrade five types of defenses on the grid using gold dropped by defeated enemies. Command a knight to fight on the front lines, using powerful cooldown abilities like Ground Slam and Thunder Strike to clear crowds. Every 10 waves brings a boss that permanently increases future enemy difficulty by 10%. Every third wave grants a permanent relic upgrade. The run ends when your wall's 650 health reaches zero.

Tips

  • Spike Traps cost $75 and slow enemies for 2.8 seconds while dealing damage over time, making them perfect for delaying heavily armored foes.
  • Cannon Towers deal heavy splash damage but cannot hit flying enemies, so ensure you build Archer or Magic Towers for essential anti-air defense.
  • Bosses appear every 10 waves with 900 base health and special powers like Meteor strikes or Ironhide armor that reduces non-magic damage by 28%.

FAQ

How do I heal the wall?
You can repair the wall by tapping it and selecting the Repair option, which costs gold. You can also pick the High Ramparts relic to increase max health and heal 160 HP.
What happens when my knight dies?
If your knight's health reaches zero, they will recover at the wall for exactly 4.2 seconds before returning to battle with 72% of their maximum health restored.
How do I get more gold?
Defeating enemies drops gold coins. Elite enemies and bosses drop treasure chests with up to 90 gold. You can also select the Royal Tithe relic to increase all enemy gold drops by 25%.
