Night Raids bring recurring enemy pressure straight to your raft or base. The warning tells you which threat is coming, and quick preparation matters because the ocean does not respect bedtime.

All Night Raids
Raid warnings identify the incoming threat and whether the raft or base needs attention. Use that signal to arm up, heal, clear movement space, and put defensive structures to work before the attackers settle in.

- Enemies

- Strategy
- Keep moving against gunfire, clear ranged pirates early, and use raft defenses or an Auto Turret to limit boarding pressure.

Reading raid warnings
Treat every raid warning as a signal to stop wandering and prepare. Do not plan around a fixed day: Buku attackers can arrive with little warning, while Kraken and mothership messages tell you to get ready for that night.
The wording also shows where the danger is headed. Ghost Pirates and the Kraken pressure the raft, while the mothership warning announces an Alien attack on the base.
Preparing your defense
Keep weapons and healing ready, then clear enough room to move without getting trapped by your own raft setup. An Auto Turret can reduce incoming pressure while you deal with enemies that need direct attention.
Ghost Pirate and Buku raids mix close-range attackers with ranged pressure. Clear gunners and other ranged enemies early, then deal with the melee group instead of letting both sides turn the deck into a very small problem room.
The Kraken needs open deck space and advance preparation for a sea fight. Alien attacks put more focus on base defense and positioning, so avoid getting surrounded while the Auto Turret helps control the approach.
Kraken Raid vs Ancient Squid
The Kraken Raid is an announced attack on the raft at sea. The Ancient Squid is a separate boss encounter summoned with tablets, so do not use the two names for the same fight.
