Our take on Planet Nine
The defining setup is a clone piloting a customizable mech on an AI-assigned mission to defend the Ninth Planet from an invasion.
What is Planet Nine?
Play as a clone sent by an AI to defend the Ninth Planet from an alien invasion.
Explore open terrain, caves, and vaults in a top-down view, following missions and side missions while also roaming freely. Combat pits the mech against hostile mechs, monsters, and raiders; energy and shields support survival, while drones, flares, and sensors provide combat tools. Find loot in containers, gain levels and perks, and use more than 100 mech parts to customize the machine. Data logs reveal the planet's history as exploration progresses. The game combines mission-based play with free exploration and RPG elements, and is single-player.
