Dredge is a fishing adventure game with Lovecraftian horror lurking beneath the surface. By day, you fish, sell your catch, and upgrade your boat in a picturesque island archipelago. By night, the fog rolls in, your sanity drops, and eldritch creatures appear. The fishing gameplay uses satisfying minigames for each rod type, and the inventory management (tetris-style fish arrangement) is engaging. Five distinct regions each contain a relic tied to the main mystery, and aberrant fish (mutated versions of normal catches) hint at the cosmic horror beneath the waves. The atmosphere is masterful — dread builds gradually through subtle visual and audio cues.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
fishing
Different fishing equipment catches different fish: rods for coastal fish, nets for open water, pots for crustaceans, and trawls for deep-sea catches. Each fishing action uses a timing minigame that varies by equipment type. Fish have specific locations, times of day, and weather conditions for spawning.
boat upgrades
The boat has slots for: engine, hull, rods (4 types), lights, and cargo space. Upgrades are purchased from the Shipwright using materials and money. Engine speed determines travel safety (faster = less time exposed at night). Hull upgrades add durability. Light upgrades push back the darkness further.
eldritch encounters
At night, sanity drops and eldritch phenomena appear: phantom rocks, ghost ships, tentacles, and aberrant creatures. Lower sanity causes hallucinations (phantom obstacles, false fish indicators). Some story events only trigger at night. Managing the day/night cycle is the core survival tension.
time management
Time passes as you fish, travel, and complete tasks. Day is safe; night is dangerous. Planning efficient routes to maximize fishing during daylight and returning to port before dark is the primary strategic consideration. Time also affects fish spawns — some species only appear at certain hours.
inventory tetris
Your cargo hold uses a grid where fish occupy different shapes (1x1, 1x2, 2x2, L-shaped for aberrant fish). Fitting maximum fish into your hold requires spatial arrangement. Aberrant fish have unusual shapes that complicate packing. Cargo upgrades expand grid size.
Builds Overview
| Build | Tier | Playstyle | Key Stats |
|---|---|---|---|
| Speed Boat | S | Move fast between fishing spots, complete multiple catches per day, and always return to port before midnight. | Engine speed, light range, fuel efficiency |
| Fishing Vessel | A | Equip all rod types to catch everything available. Focus on completing fish encyclopedia entries and fulfilling NPC requests. | Rod variety, cargo space, moderate speed |
| Cargo Hauler | A | Fill the entire cargo hold before returning to sell. One efficient trip replaces three small trips. | Cargo space, fishing speed, engine speed |
| Night Fisher | B | Fish during night hours for rare catches, manage sanity carefully, and use lights to keep eldritch horrors at bay. | Light range, engine speed, sanity management |
| Explorer | A | Systematically explore each region, find hidden islands and underwater features, and collect all relics for the story. | Engine speed, light range, exploration coverage |
Speed Boat (S-Tier): Prioritize engine upgrades for maximum travel speed. Speed keeps you safe at night and covers more fishing ground during daytime. The fastest engine lets you cross entire regions before sundown.
Fishing Vessel (A-Tier): Balanced build with all four rod types installed for maximum fish variety. Each region has fish requiring specific equipment. The Fishing Vessel covers all bases without specializing.
Cargo Hauler (A-Tier): Maximum cargo hold upgrades for transporting large quantities of fish per trip. More fish per trip means more income per journey, reducing travel time spent on returns. Best for resource grinding.
Night Fisher (B-Tier): Light upgrades and sanity management for extended night fishing. Some rare fish and aberrant variants only appear at night. Night Fishing is riskier but more profitable due to rarer catches.
Explorer (A-Tier): Engine and light focus for exploring every corner of the map. The Explorer seeks out hidden locations, aberrant fish, and story relics. Exploration uncovers the full story and most valuable catches.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Rod | The basic fishing tool for catching coastal and near-shore fish. | Fishing Vessel |
| Net | Catches fish in open water while your boat is moving. | Cargo Hauler |
| Pot | Crab and lobster pots placed at specific underwater locations. | Cargo Hauler |
| Trawl | Deep-water fishing equipment for rare species found only in deep ocean areas. | Night Fisher |
| Dredge Equipment | Specialized equipment for pulling items from the ocean floor. | Explorer |
Rod: The basic fishing tool for catching coastal and near-shore fish. Different rod tiers increase catch speed and reduce minigame difficulty. Rods are the most versatile equipment and catch the majority of fish species.
Net: Catches fish in open water while your boat is moving. Nets passively collect fish as you travel between locations. Upgraded nets catch rarer open-water species. They complement active rod fishing.
Pot: Crab and lobster pots placed at specific underwater locations. Drop a pot and return later to collect the catch. Pots provide passive income while you fish elsewhere with rods. Crustaceans sell for good prices.
Trawl: Deep-water fishing equipment for rare species found only in deep ocean areas. Trawling uses a specific minigame and catches the most valuable fish. Deep-water areas are more dangerous (further from shore, closer to eldritch zones).
Dredge Equipment: Specialized equipment for pulling items from the ocean floor. Dredge catches include relics, materials, and unique treasures. The Dredge mechanic is central to the story progression — key items are dredged from specific locations.
Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Greater Marrow | Starting region | Tutorial, basic upgrades, first relic, safe fishing grounds |
| Gale Cliffs | Second region | Gale Cliffs relic, wind-exclusive fish, boat upgrade materials |
| Stellar Basin | Third region | Stellar Basin relic, volcanic fish, aberrant varieties |
| Twisted Strand | Fourth region | Twisted Strand relic, swamp fish, horror story revelations |
| Devil's Spine | Final region | Final relic, story conclusion, rarest fish species, deepest catches |
Greater Marrow: The starting region with the main port town. Greater Marrow teaches basic mechanics with safe daytime fishing and mild nighttime dangers. The Shipwright, Fishmonger, and Lighthouse researcher are based here.
Gale Cliffs: A windy coastal region with cliff-side fishing spots and dangerous currents. Contains unique wind-dependent fish species and the second story relic. The weather system (storms, fog) is more aggressive here.
Stellar Basin: A volcanic region with hot springs and unique thermal fish species. Contains the most aberrant fish varieties. Night dangers are particularly intense here due to volcanic activity attracting eldritch creatures.
Twisted Strand: A mangrove swamp region with narrow waterways and ambush predators. Navigation is challenging through tight passages. Contains the darkest atmosphere and most horror-focused story content.
Devil's Spine: The final region with the deepest waters and most dangerous eldritch presence. Contains the final relic and the story climax. The ocean here is dark, deep, and full of the largest creatures. Only approach with a fully upgraded boat.
Tips That Actually Matter
- Sell aberrant fish to the Travelling Merchant (appears periodically at docks) for bonus money — the regular Fishmonger pays less for mutated catches.
- Upgrade your engine before anything else. Speed determines how much you can accomplish each day and how quickly you escape night dangers.
- The Lighthouse researcher offers permanent ability upgrades in exchange for research materials found while fishing. Prioritize these upgrades for long-term benefit.
- Fish spoil over time in your cargo hold. Sell catches promptly or they lose value. Plan routes to return to port before your hold is full of old fish.
- Each region's relic requires specific steps to locate (usually following NPC questlines). The relics are the main story progression — collect all five for the ending.
- Night fishing is more profitable but riskier. If you choose to fish at night, stay near shore and keep your lights on. Darkness meters drop faster far from land.
- The inventory tetris puzzle is real — oddly shaped aberrant fish waste cargo space. Sometimes selling a large oddly-shaped fish to make room for multiple smaller ones is more profitable.
- Hidden islands and underwater features appear when you explore thoroughly. Some contain unique fish species only available at that location.
- The story has multiple endings based on a choice at the climax. Both endings are worth experiencing — save before the final decision.
- Talk to every NPC multiple times across different story stages. Their dialogue changes and reveals additional lore and side quest triggers.
Common Mistakes to Avoid
- Staying out past midnight without lights — sanity drops rapidly in darkness, causing hallucinations that make navigation dangerous and potentially fatal.
- Selling aberrant fish to the regular Fishmonger instead of the Travelling Merchant — you lose significant bonus value.
- Neglecting engine upgrades — a slow boat spends more time traveling (burning daylight) and can't escape night dangers quickly.
- Ignoring the research system at the Lighthouse — permanent ability upgrades from research significantly improve all gameplay aspects.
- Trying to complete all fishing in one region before moving on — the story pushes you between regions, and returning to previous areas later is easy with upgraded boats.
Frequently Asked Questions
How long is Dredge?
The main story takes 8-12 hours. Completionist fishing (catching every species) adds 5-10 hours. The Iron Rig DLC adds a new region and 4-6 hours. Total completion is roughly 20-25 hours.
Is Dredge scary?
Mildly. Dredge builds atmospheric dread through visual and audio cues rather than jump scares. Night sequences create genuine tension. The Lovecraftian horror is subtle — unsettling rather than terrifying. Players uncomfortable with deep water and darkness will find it more impactful.
Is there combat in Dredge?
No direct combat. Eldritch creatures damage your boat but you can't fight them — only flee or avoid them. The game is about managing risk (when to fish, when to flee) rather than fighting. Your 'weapons' are speed, lights, and timing.
Does Dredge have DLC?
Yes, The Iron Rig DLC adds a new region (an industrial rig), new fish species, equipment, and story content. The Pale Reach DLC adds an icy region. Both are standalone additions worth purchasing for fans of the base game.
