Project Hastur

Project Hastur combines 3D tower defense and real-time strategy with biological evolution. As a military defense commander, you build and upgrade defenses on a hex grid to fight alien Proteans, whose evolving abilities, behavior and appearance respond to your strategy.

The Protean threat

Each creature has its own genome, which controls its abilities, behavior and appearance. Proteans that travel furthest and deal the most damage to your defenses have the most offspring in the next generation. As they evolve, they gain new weapon resistances, behaviors and movement capabilities, making each playthrough different.

Defend the hex grid

You choose which of four turret classes to build, when to upgrade them and where to place them. You can also call in airstrikes and deploy combat robots. Airstrikes can change the course of a fight, but you must wait before using one again. As you progress across the Nyx system, you unlock powerful upgrades for each turret class.

Game modes

In Campaign Mode, you fight across a series of maps to protect the planet Nyx from the Protean swarm. You unlock weapons and upgrades along the way and learn about the mysteries of Project Hastur.

In Experiment Mode, you can select any map, adjust its parameters and play indefinitely. Change the number of creatures and the parameters of evolution, make your turrets invincible, or increase the biomatter and try out the most powerful turret upgrades.
