The game

What is Lonekeep?

An idle castle defense game in portrait. One fortified keep stands in the middle of the map and the siege closes in from every side, wave after wave. You never aim and never place towers: your weapons fire on their own. Your job is to decide where the gold goes.

How it plays

  • Build the wall your way. Twelve defenses, from ballista and cannon to tesla coil, frost, tide and prism. Mount them on four slots, level them up and mix elements against what each world throws at you.
  • One button that matters. Each run you pick a single ultimate: drop a meteor on the thickest pack, freeze the whole field, ring the walls with fire, mend the keep or call out the garrison. One press, then a long recharge.
  • Six worlds, then the frontier. Every named world has its own weaknesses and resistances. Beyond the sixth, endless frontier worlds keep going, growing up to twenty waves.
  • Come back richer. Crowns keep flowing while you are away. Spend them in the Great Hall on permanent upgrades: thicker walls, sharper bolts, deeper coffers.
