Ex Vitro

Ex Vitro is a retro-style action game about exploring a facility in a galaxy where humanity faces extinction. You uncover the story through hidden journal entries, learn the nature of the main character and their role in the conflict, and fight your way through eight biomes.

Humanity's last war

By the end of the twenty-second century, Earth has become a dry, arid husk, with billions of people crowded into disease-ridden shelters. Humanity seeks salvation among the stars, using desperate new technologies to establish interstellar colonies. After encountering alien life, humans conquer isolated worlds and claim them for their expanding population.

The conquered worlds leave humanity with enemies across the galaxy. Survivors from fallen alien worlds unite in a campaign of revenge, overwhelming human forces until only a few million people remain in scattered pockets among the stars. Facing extinction again, military leaders turn to weapons that warp reality, genetically splice captured alien species into abominations and build artificial intelligences without ethical or moral restraints. Some people oppose this course: while some try to reason with the leaders or refuse their orders, others decide to act.

Explore and fight

You travel through eight biomes, each with its own inhabitants, secrets and traps. Along the way, you collect and upgrade powerful weapons, fight multiple massive bosses and find journal entries that reveal the grim fate of humanity and its war against the galaxy.

The game includes teleporters, rechargeable ammunition and an area-by-area item collection tracker. Your item completion determines which of the two endings you unlock.

Bonus pack

The bonus pack includes instructions for building a terrarium, with tips from the Facility Administration on caring for genetic abominations. It also contains three original music tracks by Sam Bionn, high-resolution concept art of the character, final boss and ending slides, and wallpapers in various resolutions. For creators, it includes royalty-free sprite sheets of unused graphics with behind-the-scenes descriptions of why they were left out, as well as eight royalty-free tilesets covering every environment in the game.
