Explore the ruins of the human race and discover the thriving wildlife that blossomed after our extinction in this underwater action/adventure. Encounter monstrous creatures and let curiosity guide you through an inevitable voyage of extinction.

The Aquatic Adventure of the Last Human is a pixelated, side-scrolling, underwater action-adventure game about exploring the decaying ruins of our species -- and fighting deadly sea-creatures -- in search of answers about our downfall.
We think it's important to bring up global issues that have affected our lives and try to give a different point of view: climate change, terrorism, and technological progress. We’re not lying: You are the last human; humanity is doomed.
The water rose by an unpredictable amount due to climate change. The Earth's surface froze over, and humans were forced to live underwater -- where they could still harvest energy and grow food -- changing how cities and districts looked. As resources began to dwindle in the year 2971, sub-aquatic spaceships were sent to a nearby wormhole to look for habitable planets. Things did not go as planned. And now the ship, Argo9, has returned thousands of years later in a time after humans have gone extinct. It's up to you to determine whether the ruins of our species is a travesty or an inevitable conclusion as you explore the lush aquatic world and encounter deadly underwater monsters.
This edition includes a pixel art map with all the boss locations, the full soundtrack composed by Karl Flodin -- and a digital booklet that gives some extra information about the story, weapons, and upgrades. Lastly, you'll receive a few desktop backgrounds that we made. All of this will be found in the game's folder.
