Flotsam Beginner Guide: First-Day Water, Food & Buildings (1.0)

The first in-game day sets the shape of the whole run. A new Flotsam town has a central Townheart, a few drifters and a lot of floating junk nearby; the mistake is to treat the junk as scenery and start building before the basics are secured. The order below is the one two independent beginner guides agree on, cut down to what actually matters in 1.0.

What you start with

You begin with a Townheart and a handful of drifters. Public beginner guides put the starting crew at three founders, and the game asks you to pick their story traits before the town opens. Every drifter carries two story chapters, each worth a minor +5 bonus to two stats or a major +10 to one; a perfect combination can reach +20 in a single stat, and rescued drifters roll theirs randomly.

The three-founder start and the +5 / +10 / +20 trait ranges come from the two public beginner guides, not from an official stat sheet. The 2020 guide was written for 0.3.7, so treat the exact rarity as approximate.

Founders are the only drifters whose traits you choose, so use that choice. A crafter with a high Crafting bonus speeds up Floaters, planks and every early build; a second founder in Cooking or Desalination keeps the two survival chains moving. Athletics, Nautics and Construction are reasonable secondary picks for hauling, salvaging and building.

First-day build order

The sequence is short, and every step removes a bottleneck that would otherwise stop the next one.

1. Collect the floating plastic and driftwood first. The current carries debris away, and the first minutes are the cheapest time to grab it.
2. Build a Plastic Recycler and auto-queue Floaters. Plastic waste has no other use, and Floaters are the currency for platforms and most early buildings.
3. Build walkways outward, then two Drying Racks and two small Storage Yards. Dry wood is the input for planks, and storage fills faster than the starting capacity suggests.
4. Build a Woodworking Shed once you have dry wood. Queue planks continuously; both power and water depend on them.
5. Spend the first four planks on a Manual Power Generator. Do this before the town runs out of energy, not after.
6. Spend the next four planks on a Desalinator. Keep firewood queued at the same time. This is the step that prevents the classic water collapse.
7. Fix food with metal, not seaweed. Find a point of interest with Metal Scrap — Factory Ruins and Abandoned Motor Boats are the usual early ones — build a Scrapsmith, auto-queue Metal Plates, then add a Mooring Point, a Fishing Boat and a fish-cooking building.
8. Only then expand. More storage, a dedicated yard per material, the Food Truck and Large Desalinator research, and eventually 15–20 drifters.

The order above matches the 1.0-era Treyex beginner guide step for step with the 2020 Steam Quick Start Guide. The specific costs — four planks for the generator, four more for the Desalinator, two Drying Racks and two small storage yards — come from those guides, and storage sizes changed in the 1.0.1 update. Check the current build menu before budgeting.

Water is the run-killer

The one-line version: without fresh water, even a well-planned flotilla collapses quickly. The Desalinator burns firewood to turn seawater into drinking water, so it needs two inputs, not one. Building the machine and then letting firewood run out is the same failure with an extra step.

A Solar Still produces water passively once you can research it, and a Large Desalinator later turns the whole chain into background infrastructure. Both are upgrades to the same problem, not replacements for the first Desalinator. The full chain, including the building-name trap between old "Distiller" guides and current "Desalinator" guides, is in how to get fresh water.

Food: seaweed is not a plan

Seaweed is available early, but both 1.0-era guides treat it as too slow to carry a growing town. Fish is the reliable income, and the fish chain starts with metal:

1. Locate a Factory Ruins or Abandoned Motor Boats landmark with Metal Scrap.
2. Build a Scrapsmith and auto-queue Metal Plates.
3. Build a Mooring Point and a Fishing Boat.
4. Add a cooking building — public 1.0 guides call the early one Fish Sticks, while the official store screenshot shows a Fryer producing Fried Fish. Check the build menu label in your own build.
5. Keep canned food as a buffer until the boats are producing consistently.

The full chain, including farms and the Food Truck, is in how to get food.

Pollution and sickness

Flotsam has no combat, but it does have a health system. The Steam store page warns that the old world is polluted and your drifters can get sickOfficial. Polluted zones and ruins are the places where that happens, and the store page lists clean food and pollution-born cures as the answer.

The 1.0 upgrade system adds a direct tool: an Air Filter installed in drifter homes reduces pollution every sleep cycleOfficial. That makes housing upgrades part of survival, not decoration. Do not park a growing town next to a polluted landmark and assume the sickness will sort itself out.

Mistakes that end runs

• Letting scrap drift away. The early debris field is a one-time bonus; grab it before the current moves it.
• Running out of power before the generator. Four planks sounds trivial until the workshops stop.
• Building the Desalinator but not feeding it. Firewood is a second production chain, not a one-off cost.
• Ignoring storage. Overflow halts production. 1.0.1 added storage filters and a 300-unit Huge Storage Yard for exactly this reason.
• Expanding the town before water and food are stable. More drifters means more consumption; add people after the supply lines hold.
• Building cramped. Players report that the Desalinator and upgraded storage have larger footprints than the buildings they replace, and moving buildings is expensive. This is a player complaint from the Early Access era, not a verified 1.0 rule, but leaving room costs nothing.
• Mixing old guides with the current build. Old guides call the water building a "Distiller"; 1.0-era guides call it a "Desalinator". Treat them as the same role unless the build menu says otherwise.

What changed since the 2019–2020 guides

The 2020 Steam Quick Start Guide was written for 0.3.7. Its build order still matches the 1.0-era guide, but several systems around it changed:

• 1.0 (4 December 2025 UTC; 5 December in Taiwan and Hong Kong): full main story and ending, four specialists with questlines, two new regions, building upgrades and 10 advanced buildings.
• 1.0.1 (29 January 2026): storage filters can be copied between yards, a Huge Storage Yard holds 300 resources, Medium Storage was reduced to 40, a buildable overview tab was added, and drifter pathfinding improved.
• Weather (2026): weather zones are being tested on the Experimental branch as 1.1.0e04. They are not part of the default 1.0.1 build, so do not plan a normal run around them.

What this page has not verified

Checked against public sources on 6 November 2026, not played through in 1.0.1f7:

• The exact number of starting drifters and the trait rarity table;
• The current plank cost of the Manual Power Generator and Desalinator;
• Current storage capacities after the 1.0.1 rebalance;
• Whether the early cooking building is labelled Fish Sticks, Fryer, or both in the current build;
• Whether the 2020 guide's two-Drying-Rack / two-storage-yard opening is still the most efficient start.

If the in-game build menu disagrees with this page, the build menu is right.
