3D Defenders

3D Defender is a first-person shooter in which you defend your planet from invading alien ships. Fly across the planet’s surface while using radar to locate nearby enemies.

Destroying an alien ship earns 250 points, while allowing one to land costs 50 points. Landed ships can still be destroyed when they take off again, recovering the lost points. Avoid enemy lasers, alien ships, and the planet’s surface, with an altimeter helping you maintain a safe distance. Each hazard costs one of your 10 shields.
