The Mission Map is a map that shows the locations of all Mission Shells. It costs 60 gems and also claims to help you find them, but in practice it cannot be recommended unless you are having serious trouble finding mission shells, or simply have nothing left in the store to buy. Found shells are omitted from the map, so this map is only useful as a pointer, not as a log. It is helpful though, because some stronger sharks' shells are often very well hidden and almost impossible to find without this map.
The Basic Map is required to unlock the Mission Map.
- There are maps on the internet that reveal the positions of shells, so if you utilize these you won't ever need the Mission Map.
