Flotsam Walkthrough
Version 1.0 has a complete story: build the radio, recruit the specialists, follow the “???” signal, build the shield, cross the polluted city and reach the island — or finish the spaceship.
Phases, not quest titlesChecked 2026-11-07
Phases, because the objective names are not official
The 1.0 announcement is the source for “there is a story now”: specialist personal quests, radio signals you choose, and two new regions. The beat order I will write comes from an achievement guide, which is a player document and in places a translation. I use phases so a mismatched quest title does not send you hunting a string the English client never shows. Phase one is the first survivor and the Radio DJ. Phase two is the Radio Station. Phase three is collecting the specialist set, two quests at a time. Phase four is the “???” radio target, a shield, the crossing of the polluted city, and the island. The spaceship is the other finish, not a detour you owe the island ending.
Ending achievements on 7 Nov 2026: End of the Line 8.2%, A Space-Ship! 9.3%, No Drifter Left Behind 6.8%. Those percents are a snapshot.
Ship shopping list from one guide
The same achievement guide names ship parts and the benches: Space Meal from the Deep Fryer, fuel from the Oil Refinery, a cockpit interface and advanced electronics from the Advanced Electronics Workshop, coolant from the Chemistry Lab, and Aluminum Sheet from the scrap workshop. I have one source for that shopping list. If your bench names differ by a word, trust the function (fryer, refinery, chem lab, scrap) over my spelling. The island route does not require that shopping list. Mixing the two endings into one checklist is how people stall in the polluted city building coolant they do not need yet.
Questions
How long is the story?
No official hour count. A guide’s 15-hour achievement estimate is on the achievements page and is one author.
Are there two endings?
The island clear and the spaceship are both represented by achievements. I do not have official ending names beyond those achievement titles.
