URIDIUM / Hewson / Commodore 64
Uridium is kind of a more limited version of Fantasy Zone, where you can travel left and right at will but can't scroll the screen up or down.
Each level has you destroying turrets and stuff on the surface of a space battle cruiser while fending off waves of enemy ships.
It was pretty cool for 1986, but nowadays it's probably not going to hold anyone's attention for too long. For C64 nostalgia trippers only.
