Professional Fishing 2 frames angling as a calm, exploratory simulation. Players travel across large maps inspired by different regions, choosing their own waters rather than following predefined fishing spots. The surroundings are part of the experience: a day-and-night cycle, changing weather, wildlife details and a nature-focused soundtrack accompany the search for fish.
Progression runs from novice angler toward legendary catches, with a broad variety of species and rare colour patterns to pursue. The Fishpedia offers information about fish preferences, habitats and favourite baits, while learning different techniques and equipment supports the practical side of the hunt. Special catches can become trophies in a customizable residence, where players can arrange taxidermies and an aquarium. Normal and hard modes offer different approaches, from more dynamic fishing to a more challenging, changing experience.
The game supports solo play as well as sessions with friends, including online co-op according to its listed categories.
