Biodome Bastion

Biodome Bastion is a tower defense game about an expedition stranded on a hostile alien planet. With its spacecraft beyond repair and no rescue in sight, you build a fortified outpost against waves of towering insectoid creatures. As the campaign progresses, you uncover the mystery of a species that can adapt to any environment.

Build your defenses

Construct defensive towers and utility structures, generate resources and manage your power grid. Plan your layout to strengthen your defenses against increasingly dangerous attacks. Survive elite waves to earn Technology Points, which unlock new defensive structures and strategic options.

Face the alien forces

Enemies attack from the ground and air, with powerful evolved elite variants and boss encounters testing your defenses. The campaign spans 30 levels across three biomes, each with new environments, enemy types and challenges. These encounters gradually reveal more about the alien ecosystem.

Study the creatures

As you meet new lifeforms, add information about them to your Bestiary and learn how their evolution lets them thrive across different climates.
