Citadel

Citadel is a comparatively slow-paced shooter that emphasizes planning and careful movement over fast reflexes.

On a planet that was thought to be uninhabited, an underground city complex has been discovered. The player's task is to explore this city with a remote-controlled hoverdrone, called Monitor, while trying to avoid its automatic defense systems.

Monitor is controlled from a top-down perspective and can only be moved into four directions, holding down the fire-button enables it to shoot in eight directions. There are various stationary and moving enemies that activate when Monitor gets close enough and start shooting when it moves. Some can shoot in four, others in eight directions, while others only try to ram the monitor or attack with homing shots.
