Evofish, a new party game from developer Moving Player, has been approved for release on the Wii U eShop. It will be available “shortly” in Europe, with no announcement so far for other regions.
Evofish includes a solo mode, as well as three multiplayer party modes supporting up to five players using the Wii U GamePad and four Wii remotes. Multiplayer will include the option to play competitively or cooperatively.
The game involves conquering the ocean by evolving your fish from prey to predator. Players will be able to unlock new fish and other content.
