Catching fish in Roblox games is fun, something easily proven by the slew of fishing titles available on the platform, but few of them match the uniqueness of Abyss, where you can capture over 500 species using a harpoon instead of a traditional rod.
That twist alone creates its own gameplay quirks, but it is far from the only thing that sets the experience apart. Abyss is packed with secrets waiting to be discovered beneath the surface. Some stand out more than others and, if that is what you are spearing for, then you will want to pay close attention to Abyss Mutations.
In the game, mutations are special attributes that alter a fish’s visual appearance and function as a core mechanic for increasing profit. These traits can appear uncommonly while exploring the ocean, usually through Natural Spawning or during specific Weather events. While most mutations boost a fish’s sell price, some can significantly decrease its value, adding a layer of risk to every haul.
