Uridium

In practice, each level takes place at a fixed altitude just above the surface of the Dreadnoughts. The screen scrolls horizontally in both directions as the Manta flies over the Dreadnoughts. Each Dreadnought has a different configuration of walls and other structures which must be negotiated in order to reach the landing zone. This task is hampered by squadrons of enemy fighters that attack the Manta in waves.

Lastly, flashing ports on the Dreadnought's surface release homing mines that cannot be destroyed. It takes a skillful Manta pilot to outfly the mines until they self-detonate.

The plot of Uridium is described as follows:

The solar system is under attack! Enemy Super-Dreadnoughts have been placed in orbit around each of the fifteen planets in this galactic sector. They are draining mineral resources from the planetary cores for use in their interstellar power units. Each Super-Dreadnought seeks out a different metal for its metal converter.
