Beacon Keep
🏯 Hold the Mountain Road
A tower defense on the ancient frontier: four towers against three kinds of enemy across 20 waves — and weather that changes the math.
✨ Features
- 4 towers — crossbow, catapult, fire oil and horse snares
- 3 enemy types — infantry, cavalry and siege carts
- 20 waves per map, with a boss push at the end
- Weather changes the math — rain halves fire oil and scatters arrows
- 8 maps × 3 difficulties with star ratings
- Precomputed paths — no pathfinding spikes, no lag
- 25 enemies on screen at 60 fps even on wave 15
- Upgrade paths for every tower
- Original music & sound effects — one-tap mute toggle
- English by default, one-tap switch to Chinese at the top-right
🎮 How to play
- Pick a tower, then tap a spot along the road to build it.
- Earn gold from kills; upgrade or add towers between waves.
