Container Shelter — Both Meanings, Straight
Ask about "containers" in this game and you're asking two different questions. One is a structure you build. The other is loot you raid. Here's each, with what's confirmed and what isn't.
Meaning 1: the buildable Container Shelter
The Container Shelter is a real, named build that players actively grind to unlock — how-to demand for crafting it is among the biggest for any structure in the game. It serves as enclosed housing on your raft: walls and a roof between you and whatever the night sends.
What no trusted source has published: the exact recipe or unlock condition. You'll find a "20 Scrap Metal + 10 Wood" figure on some wiki-style sites — the same sites that publish invented promo codes for this game — so we don't repeat it as fact. We're verifying the real recipe in-game and will stamp it here; if you unlocked it recently, the build menu will show the requirement directly.
Meaning 2: Cargo Ship containers
The Cargo Ship is an enterable encounter — a hulking vessel whose container holds carry some of the best mid-run loot, including up to two Medkits per ship. Getting its doors open is a famous head-scratcher; door-route demand is real, and it's on our in-game verification list.
If you're container-hunting for supplies rather than housing, this is the meaning you want — pair it with the Medkit sources list.
FAQ
What is the Container Shelter in 100 Days At Sea?
A buildable/unlockable structure in the crafting system that players use as raft housing — one of the most-asked-about builds in the community. The exact recipe and unlock condition haven't been documented by any trusted source yet; recipe numbers floating around come from sites with a fabrication record.
How do I get Medkits from containers?
Different containers — the lootable ones aboard the Cargo Ship. Board it, work through the container rooms, and you can find up to two Medkits per ship among the loot.
Does the Container Shelter protect against storms?
Storms themselves are unconfirmed — no trusted source mentions storm weather in this game at all. Until that's verified, treat 'storm protection' claims as invented. What a shelter certainly does is give your raft defensible, enclosed structure for the night threats that definitely exist.
