Quick answer
The official ShoreTiles description says that new lighthouses push back fog, help expand the island, and connect to progression that unlocks buildings and units. It also mentions chests and relics. That establishes the theme of the system, but not a complete construction or unlock table.
Confirmed at description level
- New lighthouses can push back fog.
- Expansion creates more room for the island and its planning layer.
- A progression map is associated with building and unit unlocks.
- Chests and relics are part of the described exploration/progression layer.
Why the lighthouse matters
For a beginner, the lighthouse is best explained as a bridge between seeing more of the island and making further progress. The official description places it alongside fog and expansion, so it is reasonable to treat it as a central planning element. It is not reasonable to promise a specific radius, price, or number of tiles revealed without a source.
The day/night context still matters. The beginner guide explains the broader official loop, while the night defense guide covers the separate defense questions that players raise around the island.
Fog and expansion
The public description gives us a directional relationship: build or discover new lighthouses, push back fog, and expand what can be planned. It does not tell us whether fog clears in a fixed radius, whether all fog behaves the same way, or whether expansion has a fixed cost. Those details belong in a versioned table only after a reliable current source exists.
Do not turn these into facts yet
- Lighthouse range or coverage radius.
- Gold cost, placement limit, or prerequisite.
- A fixed fog-clearing order or reward.
- A complete progression-map route.
- Exact chest or relic effects.
Progression map, chests, and relics
The progression map is mentioned in the official description as part of unlocking additional buildings and units. Community discussions show that players have questions about building and troop purpose, which makes this a useful content area. At this stage, the page should tell readers what the official description promises and point out what still needs a current explanation.
Chests and relics can be listed as described elements, but not as a detailed reward catalog. Avoid implying that a specific chest always contains a specific item unless an official or clearly versioned source supports it.
How to keep the page useful without inventing rules
- State the official relationship first: lighthouse → fog → expansion/progression.
- Link to the tile/economy page when discussing gold or placement choices.
- Keep community questions in a separate “reported confusion” section.
- Show a last-checked date whenever the release version or Demo changes.
- Upgrade an unknown only when a new source actually supports it.
Community signal
Steam discussions include questions about building purpose, troop purpose, the progression map, and camera/controls. These are valuable reasons to explain the system clearly, but they do not establish the answer by themselves.
FAQ
What does a lighthouse do?
The official description says new lighthouses push back fog and help expand the island. Exact range and cost are not confirmed here.
Does a lighthouse reveal a fixed amount of land?
That is currently unverified. Do not publish a radius or fixed tile count without a current source.
How do I use the progression map?
A community post mentions the map and the M key, but that is a player report. Check the current build before presenting it as an official control instruction.
