The Keeper's Handbook

The Tidewatch knowledge base — keep the light burning, survive the night.

Keepers defending the lighthouse light against Fog Crabs

🏮 Start Here

Tidewatch: Survive the Night is a co-op survival game on Roblox. Your crew is stranded on a little island with an old lighthouse. By day you dig for treasure, chop wood, fish and raft to nearby islands. When the fog rolls in, the monsters come ashore — and they can't stand the light.

Your first ten minutes

The run

A run lasts up to 85 nights. Your crew shares one run: the night count, the lamp oil, your forts, your lighthouse upgrades and your Crew Chest are all saved together, so a friend can continue the crew's run even if you log off. Reach night 85 and every keeper who finishes earns the title Keeper of Tidewatch, 50 Moon Pearls and a golden lamp.

Playing together: crews are stronger than solo keepers. Revives, the Thunder Conch, Rest Huts and Mossback all reward a crew that sticks together — and Glowfish hunt keepers who wander off alone.

🌙 Surviving the Night

The light is safety

The lighthouse lamp burns oil all night. Driftwood feeds it (1 driftwood = oil); Lou the Lamplighter gets 50% more oil from every piece. Inside the light ring, monsters won't touch you and you slowly heal (a heart every 20 seconds). If the lamp goes out, the light shrinks to nothing and the night gets very dangerous — keep it fed.

Hearts & hunger

Knocked out — the 20-second rule

At 0 hearts you're knocked out. A friend who reaches you within 20 seconds pulls you back up (if nobody else is on the island, the window is 8 seconds). Don't want to wait? Press Wake up now to faint right away and wake at the lighthouse — or in the nearest Rest Hut, for half the usual oil, with 1 heart. Mae the Medic's revives give the friend an extra heart.

Calm Mode

Turn on Calm Mode in Settings for a gentler game: monsters skip you entirely. It's per-player, so a calm keeper can still crew with braver friends.
