Descended is an action RPG that treats ideas of deep sea settlements and genetic manipulation.

The player's avatar is a human who has recently arrived at the bottom of an alien sea with one task in mind - to survive and keep revolutionary science safe from evil men on the planet's surface. This new science is also the key to survive the abyss, as it allows the player avatar to swiftly morph its body, alter genes, and tailor ecosystems. The seafloor is procedurally generated and will contain biomes such as Volcanic Trenches, Brine Mires, Worm Plains, and Seamounts.

In addition to the fun and games, Descended intends to incorporate and passively teach marine and environmental science by weaving gameplay mechanincs around concepts such as "marine snow", "source populations" and "invasive species". Its flora and fauna will be inspired by Earth's.
