There are many achievements to unlock in Dredge, and the following is a complete guide to all the achievements in Dredge. The game's scenes can be divided into several types, and the following will introduce them from these aspects. You can follow the specific tasks shared below, and if you can unlock all these achievements, then the player can completely dominate this sea area.

First, there are some basic achievements that can generally be gradually achieved while playing the game. After catching 250 fish with a fishing rod, you can unlock the deep-sea area and also get the achievement [Rise from the Deep]. Additionally, there is the achievement [Making a Living], which requires earning $2,500. These simple achievements are very easy to achieve. Below, I will focus on sharing some of the more difficult achievements so you can know the specific methods to unlock them. To unlock the [Equivalent Exchange] achievement, you need to frequently search the surrounding islands, dig up trinkets, and sell them. As long as you can earn a cumulative total of $1,500, you can complete this achievement.

Next, there are ship-related achievements, which are also quite easy to unlock later in the game. Every player will definitely need to continuously upgrade their ship. The first one is the [Hull Improvement] achievement, which can be completed by doing a side quest at Gairloch Cliffs, where you can obtain refined metal to quickly level up your ship. The [Light Up the Night] achievement is also easy to achieve; you just need to increase the brightness of the entire ship's lights to 3000. To unlock [Fully Equipped], you need to research ship technology and install these technological devices in all available slots.

Additionally, there are main story achievements in the game. Generally, as long as you follow the main story, you can easily unlock these achievements. In the main story, there is an achievement called [Secret], where players need to go to Gairloch Cliffs and complete the side quest [Hermit's Life]. Besides obtaining refined metal for upgrading the ship, you can also use explosives to blow up the surrounding ruins, revealing a sunken ship. Retrieve the music box from the sunken ship and deliver it to the character to complete the achievement.
The [Necklace] achievement is a combination of the main story and a side quest. You need to go to the Winding Coast, where there is a camp dock. Interact with the pilot here and help him complete the side quest [Painful End]. Then, defeat the Heart-Eater, and give the key obtained from the Heart-Eater to the pilot to complete this achievement.

There are also some challenging achievements in the game, such as [Fate], which requires players to complete all side quests. Another is [Voice in the Mist], where during navigation, the player experiences hallucinations and sees other fishing boats. At this point, the player needs to sound the horn promptly. If the other party responds, then this task can be completed. The [Spotting Prey] achievement is designed to encourage good habits, requiring the player to use a telescope to confirm before each fishing attempt.
Completing these achievements is actually very simple; you just need to follow the game's guidance and continuously complete tasks. These tasks generally do not require special effort, as they are usually interspersed with regular main and side quests.

The complete guide to all achievements in Dredge has been shared above. There are dozens of achievements in the game, but most of them are relatively easy to achieve. Each achievement is straightforward, and the ones that are more ambiguous in their setup have been highlighted above. If you want to complete them, you can try the methods mentioned above.
