While the factory isn’t the centerpiece ofDredge: The Iron Rig’s narrative, it is the place where you will go to get some of the best equipment and items in the game. Naturally, that is going to include all the good stuff like better, more efficient fishing rods, but it doesn’t end there.

Once you start to unlock more tiers of the factory, you will gain access to new ways to obtain building materials, items to help repair your ship on the fly, and even advanced baits for more efficient fishing. This guide will identify every piece of equipment available in every tier as well as how to unlock each tier.

How To Unlock Factory Tiers

You will unlock new tiers of the factory by completing the Scientist’s requests. Once you have brought the Scientist another haul of fish, you will be able to use an Ironhaven Crate to further upgrade the factory (except for the fourth tier, which will requiretwocrates).The Scientist’s requests and the factory are inexorably linked, as you can’t complete those fishing missions without acquiring the “Infused” fishing gear sold by the factory, and you can’t get access to more tiers of the factory until you complete the Scientist’s requests.

Tier 1 Factory Equipment

One of the first things you’ll do after encountering the rig is build the factory(by providing the Engineer with an Ironhaven Crate). The moment you do, you will have access to this first tier of merchandise. This first tier of factory goods includes all your go-to tools for fishing in the Iron Rig expansion.With this infused equipment, you will be able to catch every fish that is unleashed upon the world of Dredge.The Infused Rod is provided to you free of charge upon getting the factory opened, as for the rest, you will need them as you progress from island to island.

If you like, you can skip the Infused Winch and go straight for the Infused Hoist.

Tier 2 Factory Equipment

The second tier of equipment will become available after you have completedthe Scientist’s first fishing request. This tier of goods is primarily for collecting more building materials. The Material Harvest is a trawling net that will secure you building materials, while the Flotsam Trap is a Crab Pot that will grant you materials.The Siphon Trawler is a necessary piece of equipment, as it will be required for completing the Scientist’s second request.

You can assemble Ironhaven Crates with building materials in the Foundry, so something like the Material Harvester is a fantastic way to get more crates.
