First 5 minutes
Start with these player actions first. This is the chapter route, not a keyword block.
Keep Wood and Metal moving
Keep Wood and Metal moving: these are the two early resources named by the current community route.
Good enough for basicsProtect the food supply
Protect the food supply: use the starting food loop, then work toward a steadier source such as the community-reported Crab Trap.
Good enough for basicsImprove the raft
Improve the raft: make the base safer before a long sailing or island trip.
Good enough for basicsSet the next build goal
Set the next build goal: work toward Sawmill, Crab Trap and Map Radar as the run allows, checking current unlock text in-game.
Good enough for basicsDelay optional detours
Delay optional detours: classes, codes and risky islands matter less than stabilizing the first run.

Guidebook table
A compact table for scanning goals, risks and next actions.
| Goal | What to do | Why it matters |
|---|---|---|
| Use the Harpoon | Pull nearby resources in and learn the collection timing. | It starts the official resource loop without an early island trip. |
| Bank Wood and Metal | Keep both supplies growing before optional builds. | The community route identifies both as the core early crafting resources. |
| Stabilize food | Use the available food loop and work toward a passive source. | Food pressure can interrupt every other beginner goal. |
| Improve the raft | Create a stable base before long exploration. | A safer raft gives the run room to recover. |
| Choose the next build | Community route: Sawmill, Crab Trap, then Map Radar as resources allow. | This sequence solves repeat resource, food and navigation pressure. |
| Prepare for danger | Add defenses and weapons before raids or risky islands. | Preparation lets you choose fights instead of reacting late. |
| Explore with a reason | Use navigation information and return with resources or progression value. | Random sailing costs time and can expose an underprepared run. |

FAQ
How do beginners start?
Use the Harpoon, keep Wood and Metal coming in, stabilize food and improve the raft before committing to risky exploration.
What should I do on Day 1?
Slow down, learn what resources are nearby, start raft safety and avoid committing to a dangerous route too early.
What should I build first?
A current community guide recommends Sawmill and Crab Trap as early priorities, followed by Map Radar. Treat that as a practical route, then confirm current unlocks and costs in the game UI.
How do I survive the first 10 days?
Focus on resources, raft stability, defenses, weapons and cautious exploration. Treat exact day-by-day routes as still being checked.
Are medkit and revive confirmed?
Not fully yet. We need in-game screenshots before listing it a full medkit or revive guide.
Should beginners redeem codes first?
Only verified working codes should be redeemed or published. This page currently points players to the code registry for none-yet status.

This chapter keeps the route useful now and labels details that still need gameplay proof. Exact stats, coordinates, recipes and hidden mechanics stay out until a player can check them cleanly.
