Beacon Guard is a lighthouse defense game crossed with an incremental idle RPG. By night you drag your beam across a perspective-rendered sea, burning back the creatures that swim out of the fog before they crash into your tower. By day you spend the lumens they drop in the harbor shop — beam power, lens width, hull, flash charge — with classic exponential-cost upgrades that keep the numbers climbing.
The campaign runs 100 hand-seeded levels across 10 chapters, each chapter introducing a new monster species (12 in total) and ending in a boss night. Monster color marks its tier: green swarms are fodder, blue and purple hit harder, gold and blood-red are walking treasure. When you finally hit a wall, Rebirth: reset your progress for Starfire, a permanent +8% damage and income per star — then storm back through the early levels in minutes. Past level 100, the Endless Tide begins.
How to play
- Hold and drag anywhere to aim the beam. Monsters inside the cone burn and slow down.
- Tap the charge button (or Space) to release the Flash Bomb — a screen-clearing burst charged by kills.
- Unlock five more weapons as you climb: auto-striking Storm Coil, chilling Frost Lens, explosive Harbor Mortar, triple-ray Prism Split, and the Dawn Protocol.
- Monsters that reach the tower cost hull. Lose all hull and the light goes out — but you keep every lumen you earned.
- Your leaderboard score is your deepest cleared level. Rebirth never erases it.
Tips from the keepers
- Lamp Power and Lumen Prism are the two infinite upgrade lines — when in doubt, buy whichever is cheaper.
- Shielded crabs and fog weavers waste beam time; mortar shells and lightning ignore their tricks.
- Rebirth around level 25–30 the first time. Ember Memory ranks make each loop dramatically faster.
- Farm the level below your wall if you're two upgrades short — replays still pay 30%.
