Xtractor Defender

Xtractor Defender is a single-player strategy game in which you escort and protect a mobile mining platform from alien drones. You lead deployments for MinSys Corporation, an interplanetary mining company that extracts the military-grade T98 mineral. Each mission ends when the Xtractor has built its protective shield; if it is destroyed, the mission fails.

Escort the Xtractor

Each level begins with a set number of Mobile Tower Units (MTUs). They escort the Xtractor to a T98 mining point, where it must mine long enough to generate the energy needed for its shield. While it mines, you defend it from waves of Alien Drones. Once the shield is complete, the Xtractor is protected from the drones and the mission succeeds, leaving it free to mine T98.

MTUs are vulnerable while moving and invulnerable in tower configuration. You decide where to deploy and position them, and when to move them to counter drone patterns. Each MTU has its own movement speed, firing range and ammunition type. Lost MTUs are not replaced, so moving them requires care.

Missions and enemies

The game has 20 levels, each with different environments, dynamics and starting conditions. Levels one and two introduce the controls in tutorials. There is no single solution to a mission, and some drone patterns react to your actions.

Alien Drones range from very small to Titanic, with varying speeds and toughness. As you progress, the hordes grow larger and harder to defeat and predict, and the enemies become stronger, requiring you to adapt your defensive approach.

You can save your game at any point and return to a level without restarting it.
