Aquazone: Life Simulator

The game becomes gradually more difficult when more types of fish get added, which all require different care. New and better aquariums are unlocked by progressing through the game and successfully caring for fish. If the player cares successfully for the fish, they might lay eggs. This unlocks new objects that can be placed in the aquariums.

The player can unlock and choose from 22 different species of fish. There are also 18 extra fish available through separate downloadable content packs, which can be purchased with Microsoft Points.
