In “Metal Gear Solid Delta: Snake Eater,” players can collect two types of collectibles: Kerotan frogs and GA-KO ducks, totaling 64 Kerotans and multiple GA-KOs hidden throughout the game. The Kerotan frogs are small green figurines found in various areas and must be attacked with either the Survival Knife or a weapon to be registered as collected. They are strategically placed in unusual locations such as behind boxes, on rooftops, and near fences, requiring players to explore each area thoroughly to ensure no frog is missed.

On the other hand, GA-KO ducks are rubber ducks that are more camouflaged and difficult to find, often located in elevated spots like the tops of speakers or branches. Players need to use vantage points and scan their environments carefully to uncover these ducks. Some GA-KOs can be found in proximity to Kerotans, adding an extra layer of strategy as players explore the game’s named areas. Both collectibles enhance the exploration experience, encouraging meticulous searching to meet completionist goals.
