How to Beat the Whale Solo in How to Fish

Start with the good news: the proof that this fight is soloable is the main reference video itself. The entire 100% walkthrough is a single-player run, and it ends with a solo kill of the final boss — with bare fists, no less. There’s even a dedicated Steam thread for the single-player route. You don’t need a squad; you need a plan.

Why Solo Is Genuinely Harder

✕

Alone, every one of its landings is a potential run-ender — nobody else is holding aggro.

• The one-shot has no safety net. The phase-2 landing slam killed the reference runner from full health. In co-op someone else takes the next hit; solo, that’s the attempt.
• No one recovers your gear. Hits scatter your inventory, and death drops your rifle where you fell. Solo, you fight unarmed until you fetch it yourself.
• Healing can’t out-pace damage in the open. The runner’s worst attempt was “spent the whole fight eating food” — and he still died instantly right after eating to full. The solo lesson: you win with geometry, not reflexes.
• There’s chat hearsay that boss stats scale with player count — unconfirmed either way. Plan for the fight in front of you.

One reassurance: dying solo is not a hard reset. The boat respawns; your items wait where they fell. The real cost is the boss despawning and the re-summon grind.

The Solo Checklist Before Any Attempt

1. Max the Assault Rifle. Solo, your DPS alone has to beat the fight timer — farm Goblin Sharks until the rifle and every damage upgrade are bought (economy details in the full guide).
2. Stockpile food at the camp and fill up before every attempt. Food is the game’s only defense, and grabbing Foot Snails mid-fight sets you on fire.
3. Buy at least two whale baits. A solo wipe with one bait means a full re-farm loop.

The Solo Route

1. Phase 1 — use the buildings. Fight the Bowhead Whale near the camp and duck inside a house to break its dive-bombs and rolls; step out to shoot. It worked in the reference run (the whale clipped inside exactly once — bug risk, not a rule). Eat at every gap, never after a hit.
2. Kill it, carry the body to the summit crater, throw it in, and sprint.
3. Phase 2 — don’t face-tank it. Get on your boat and lure the Mutated Bowhead Whale toward Island 4 at a deliberate pace: too fast and it despawns, too slow and it catches you.
4. Wedge it between the casino door pillars and shoot from inside the casino, where it cannot touch you. Full trap mechanics on the Phase 2 page.

What a solo win looks like: the whale stuck overhead, you inside the casino, and nothing it can do about it.

5. Want the bare-hands achievement while you’re here? Shoot to critical, punch the last hit — the reference run did exactly this, solo.
6. If it despawns or you die: recover your gear, re-bait, repeat.

Common Solo Mistakes

• Assuming the fight needs co-op and shelving the game — the reference run settles this.
• Fighting phase 2 in the open. One slam ends a full-health attempt, and there’s no one to trade aggro.
• Reactive eating. Healing after a hit leaves you standing in the next landing zone.
• Panic-throttling the boat. Full speed = despawn = new whale. Deliberate pace wins.
• Starting with one bait and no food reserve — the wipe costs an hour, not a retry.

What Happens Next

The solo kill completes the Scientist’s mission exactly like co-op: expedition boat → mainland → ending. Chasing more? The bare-hands last hit was done solo in the reference run via the pillar trap, and the one-hour “Bean” run is the other endgame challenge.
