How to Beat the Pufferfish Boss

Why the pufferfish is a wall

Launch-day players consistently describe the pufferfish as extremely fast, durable and capable of ending an attempt quickly. Some report struggling even with high-end weapons. This is not a fight where “buy one more upgrade” automatically fixes poor positioning.

The boss’s large body and increasing size can also work in your favor: terrain that barely interrupts a smaller creature can disrupt the pufferfish’s route. Players report that it may get caught more often as the fight progresses, but the behavior is physics-dependent and should not be treated as a guaranteed lock.

Build a route before the first shot

1. Identify two pieces of cover. Trees or solid props should let you circle without entering a dead end.
2. Clear your escape path. Small props and shoreline angles can turn a clean loop into a collision.
3. Start near the outside of the route. Do not summon or engage while boxed between the boss and water.
4. Let terrain create the firing window. Shoot when the boss is rerouting, then move before it closes the gap.
5. Keep the loop boring. A repeatable circle is safer than improvising a new direction on every pass.

Solo approach

Enter with a weapon whose timing you already understand. The important stat is not an unpublished damage number; it is whether you can fire and return to movement inside the gap you create. Preserve ammunition for clean windows and avoid reloading while standing in the open.

If the pufferfish catches you on the same corner repeatedly, change the route—not just the weapon. A wider circle can reduce abrupt turns, while a tighter route may cause the large body to interact with cover more often. Test one change at a time so you can tell which pattern is surviving longer.

Co-op roles

Community advice is clearest in co-op: the targeted player runs circles while the others fire. Spread shooters around the arena so the boss does not pass through the whole team on one charge. Call out an aggro change immediately; the previous runner should stop crossing the new runner’s route.

Keep the fin/trophy after the kill

Do not hand the next quest giver ordinary pufferfish meat chunks. Players report that the progression item is the distinct half-piece or fin/trophy with a visible bone-like shape. Pick it up, keep it in the relevant player’s inventory and return it before selling or eating other parts.

If you are still getting one-shot

• Stop spending attempts until you have a route that avoids the first few charges.
• Check whether travel or weapon purchases emptied the cash needed for supplies.
• Use co-op players at different angles rather than stacking behind the same tree.
• Watch a current gameplay run to compare arena position, not just the final loadout.
• Check current developer notes in case launch balance has changed since this page’s update date.
