Crucial Early Game Strategies
Before you cast your first line into the ocean, establishing a few ground rules will save you incredible amounts of time and frustration. Taking a moment to understand the underlying systems will make your entire journey significantly smoother.
File Management and Multiplayer Benefits
You must maintain two completely separate save files right from the start. Dedicate one file entirely to your standard leisurely playthrough and reserve the second one strictly for the demanding one-hour speedrun challenge. Mixing these two drastically different goals on a single file will only cause massive headaches and potential progression loss.
Playing with friends offers massive advantages throughout the campaign. Multiplayer lobbies make boss encounters significantly easier because you gain extra firepower and the invaluable ability to revive fallen comrades during chaotic battles. Interestingly, weapon upgrades appear more affordable when you play solo, while standard guns and bait prices remain consistent across both game modes. You can utilize this knowledge to optimize your spending habits depending on the size of your group.
Patience Pays Off
You should completely ignore the tedious achievements until you finish the main story. Defeating the final boss returns you to the first island with your entire late-game arsenal intact. Trick shots, money farming, and collection grinds become laughably easy once you possess maximum firepower and total freedom of movement. Do not waste precious hours attempting difficult tasks with starter gear.

Island 1: Your First Catch
Your journey begins with incredibly simple tasks designed to teach you the basic controls. You simply need to catch a basic aquatic creature and eliminate it with your bare fists to secure your first effortless milestone.
The Drip Variant Economy
During this early stage, you will inevitably encounter Drip variants. These flashy creatures sport rainbow name tags and ridiculous cosmetic skins that make them impossible to miss on your screen. Whenever you capture one of these special variants, take it immediately to the Reel of Fortune slot machine located on the island. You gamble these special catches at the machine to unlock legendary weapon skins. The game continuously respawns these variants in the wild, meaning you never permanently lose your gambling currency. You can always farm more if luck is not on your side.
Tracking Down the Beer Thief
Your main objective on the starter island requires you to track down a notorious beer thief. You must attach a beer to your fishing rod to summon the formidable Spider Crab boss. Before initiating this fight, spend your starting cash to maximize the sharpness of your brass knuckles.
The crab features a distinct charging attack that deals heavy damage. You must dodge this charge at the last second and maneuver directly behind the creature to trigger a brief stun window. Unload your melee attacks continuously while it remains incapacitated. Collect the unique shell it leaves behind upon defeat and deliver it to the lighthouse keeper. He rewards you with the boat keys, which finally unlocks ocean travel.

Island 2: Upgrades and Forest Quests
Take your vessel to the second landmass to secure essential equipment and tackle your first multi-step local objective. This location provides the tools required to survive the tougher battles ahead and demands careful exploration of the dense foliage.
Essential Maritime Investments
Immediately visit the old man residing in the local shack to purchase a boat engine upgrade for 230 dollars. While a different mid-tier engine exists further ahead on the third island, this specific purchase is the most economical choice for your current progression level. You should skip the pistol entirely and invest your hard-earned funds into a shotgun. The shotgun packs enough punch to carry your combat effectiveness across multiple upcoming zones.
You also unlock access to dynamite for 25 dollars at this shop. Treat explosives strictly as a tool for rapid food gathering rather than a standard combat implement. Throwing explosives into the ocean brings dead fish to the surface almost instantly. However, detonating them near enemies usually results in an accidental demise. Cooked food serves as your primary healing source during tough battles, making dynamite a fantastic utility item for restocking your supplies quickly. You should also secure a Beginner Boss Lure for 40 dollars and store it safely in your inventory for a late-game objective.
Securing the Swamp Lady Dinner
Your primary local objective involves securing a proper dinner for a woman residing deep in the woods. Scour the tall grassy areas carefully to locate three hidden leeches scattered on the ground. Present the gathered leeches to the woman to receive your boss bait.
Cast your line into the water to reel in the dangerous Piranha boss. This creature constantly spits out smaller minions during the encounter to overwhelm you. You must treat this battle like a classic zombie survival game by constantly moving backward while firing your shotgun at the main target. Switch to your brass knuckles to rapidly dispatch the tiny spawns. Collect the severed tail from the defeated boss and return it to the forest lady to complete the quest and earn your passage forward.

Island 3: Mastering the Culinary Arts
Arriving at the third location introduces you to the highly profitable cooking mechanics. A passionate grill enthusiast blocks your path and demands a fresh shark before he shares his equipment. You must purchase the Standard Boss Lure for 280 dollars, summon the beast, and eliminate it. The island terrain features numerous tall coconut trees that can block your dodge rolls, but they also occasionally trap the enemy for easy damage. A fully upgraded Uzi handles this encounter perfectly if you maintain a safe distance.
Unlocking the Grill Station
Gaining permanent grill access completely transforms your economy. Pressing the F key allows you to inspect items and monitor their Value, Cooking multiplier, Weight, and Killscore in real time. Hover your fresh catch over the open flames and watch the multiplier climb steadily. You must remove the item when it hits exactly 1.5x. Leaving it over the fire for too long turns the food solid black, resets its value to zero, and strips all its healing properties. This lucrative cooking multiplier applies to weapons and gear as well. Always roast your old guns over the fire before selling them to vendors to maximize your profits.
Assisting the Vacationing Tourist
To progress the story further, you must aid a vacationing tourist who desperately requires an endangered species for his collection. Equip your pink standard lure and hunt patiently for a needlefish, a bowl fish, or a sea horse. The game clearly flags these specific types upon capture to let you know you succeeded.
Deliver the required specimen to the tourist to receive a carrot in exchange. Bait your rod with this carrot to face the massive Pufferfish boss. This enemy rolls toward you aggressively and expands its size throughout the fight. Dropping its health below fifty percent triggers a dangerous purple poison cloud that tracks your movements across the arena. Focus heavily on evasion, fire your weapon accurately, and consume your cooked food to survive the ordeal. Remember to purchase additional inventory and hotbar spaces here, as carrying a massive stack of roasted provisions is absolutely mandatory for surviving the endgame.

Island 4: Aerial Assaults
Speed up your nautical travels significantly by buying the Dual Motors upgrade for 860 dollars at the shack near the cooking station. Your primary goal here involves protecting the terrified locals from a massive avian predator.
Taking Cover from the Avian Threat
You must follow a very specific sequence to draw out the island boss. Buy the Professional Boss Lure for 1,200 dollars to catch a large tuna. The tuna acts as a challenging mini-boss on its own, but you must drop its lifeless body on the ground to attract the true threat.
The Seagull boss utilizes two distinct offensive moves. It performs a direct physical dive bomb and unleashes a ranged projectile with a loud audio windup cue. You counter both of these maneuvers by taking hard cover inside the local casino structure. Track the bird’s movements through the casino roof and step outside to fire only when it finishes its attacks. An upgraded sniper rifle or Uzi works wonders during this lengthy encounter.
Expanding Your Arsenal
This specific area also unlocks critical weapon modifications that drastically change how you approach combat. You gain access to sniper scopes and suppressors, which finally rounds out the four available attachment categories. Make sure to experiment with extended magazines to increase your ammo capacity, laser sights for perfect hip-fire accuracy, optics for long-distance engagements, and barrel mods to manage heavy recoil. Optimizing your damage output here prepares you for the brutal difficulty spike waiting at the final destination.

Island 5: Surviving the Volcano
Welcome to the final frontier. The volcanic environment offers massive environmental advantages while hosting the most demanding combat encounters in the entire game. Prepare to test your accumulated arsenal and your mechanical skills against the ultimate threat.
The Magic of Magma Cooking
The environment offers a massive quality of life upgrade by letting you toss items directly into the glowing lava pools. Magma instantly applies the perfect 1.5x cooking multiplier without any risk of accidentally burning your valuable goods. Spend a significant amount of time building a massive mountain of cooked provisions before attempting any major battles. You should also take this opportunity to attach modifications to all four weapon slots on a single assault rifle to secure the Fully Equipped achievement effortlessly.
Locate the military scientist wearing the bright hazmat suit. He tasks you with gathering five standard catches to fuel his research. Toss some bundles of explosives into the water to quickly gather the required quota without wasting time fishing normally.
The Ultimate Oceanic Showdown
He rewards you with the specialized bait needed to summon the standard Whale. Dodge its charging attacks and massive aerial stomps while returning fire constantly. Once defeated, you must physically lift the carcass and throw it straight into the glowing volcano to summon the true final challenge.
The Lava Whale is an incredibly aggressive volcanic variant. It rolls rapidly, crushes the ground repeatedly, and hurls flaming meteorites across the entire battlefield. The second phase amplifies the aggression by adding constant aerial bombardments that test your situational awareness. Equip your fully modified assault rifle and constantly eat your magma-roasted stash to endure the relentless onslaught. Victory grants you a special tail trophy. Deliver this item back to the military scientist to acquire the RHIB keys. Start your newly acquired vessel and enjoy the spectacular ending sequence.

Post-Game Cleanup Tactics
The credits roll and you suddenly awaken back on the starting shores with all your endgame gear and unlimited access to every zone. Now is the perfect time to dominate the remaining objectives using your over-leveled equipment without any story pressure. Because these tasks require highly specific actions across different systems, a concise checklist is necessary to track your progress effectively.
Combat Mastery and Style Points
Use your fully upgraded weapons and accumulated wealth to tackle these disconnected combat challenges:
-
- Speed Demon: Bait the Spider Crab using a beer and instantly empty your maximum level assault rifle into its face to secure a boss kill in under ten seconds.
- 360 No Scope: Equip a sniper rifle. Perform a complete physical rotation with your mouse, stop, and fire from the hip at a weak target. The game utilizes hitscan mechanics, meaning your bullets have no travel time or drop, making this surprisingly forgiving.
- The Noob: Drop a lifeless fish on the floor and unload your gun into it to generate exactly zero style points.
- Impressive Style: Equip your assault rifle with a laser sight. Find a seagull flying in the distance and fire a single tap from the hip to stack Long Range, Hipfire, One Shot One Kill, and Overkill multipliers for a massive score boost.
- Target Practice: Place an explosive stick on the dirt, drop a dead fish next to it, retreat to a safe distance, and shoot the explosive once a bird lands to eat the bait.
- The Handyman: Initiate the Lava Whale fight. Whittle its health down with your rifle until the health bar is practically invisible. Put your guns away and deliver the final blow with your bare fists.
Environmental Manipulation and Wealth
Complete your collections and manipulate the casino systems with these specific environmental interactions:
- Questionable Diet: Use the Beginner Boss Lure you purchased earlier to summon a weak enemy. Defeat it, hold the remains over a flame until it turns solid black, and consume the charred remains.
- Aviation: Toss a single explosive bundle directly under your parked vessel and detonate it to send your transport flying through the air harmlessly.
- The Ultimate Collector: Press Tab to identify missing species. Systematically hunt down every standard and Drip variant from the safety of the final island to finish your encyclopedia.
- Roulette Millionaire: Roast items in the lava until you secure a catch valued at 2,858 dollars or higher. Place these high-value goods on the green pocket of the roulette table until you secure the massive payout.

The Bean Speedrun File Strategy
The developers patched the original one-hour speedrun route in version 1.0.5. Beating the entire campaign organically under sixty minutes currently requires intense solo practice, flawless execution, and incredible luck against the final boss. However, clever players discovered a text file modification method that grants the achievement effortlessly on the current patch. Because this involves manipulating your computer directories, you must follow these precise steps in order.
Altering the Code
You can accomplish this bypass by modifying a completely fresh save state from the main menu.
- Create a fresh game file, load your character onto the starting beach, and immediately exit back to your desktop.
- Open your computer file explorer and go to your user AppData directory.
- Follow this specific path through your folders: Drive C, Users, Your Username, AppData, LocalLow, Dazed Games, How to Fish, Saves.
- Enable hidden items in your Windows settings if you cannot see the AppData folder initially.
- Locate the text document matching your save name and open it with a basic text editor program.
- Locate the variable named SpawnedIsland and change its value to the number 4.
- Locate the variable named MaxIsland and change its value to the number 5.
- Locate the variable named FinalBossKilled and change its value to the word true.
- Save your text document and launch the game application normally.
Utilizing an Existing Campaign File
You will spawn directly next to the final escape boat. Interacting with it instantly triggers the credits and awards the elusive speedrun trophy. Alternatively, if you already defeated the final boss on a legitimate file but missed the strict time limit, you can edit your existing document instead. Find your active save in the same directory and change the Playtime variable to zero before interacting with the escape vessel to trick the timer.
