Gray Lady is an arcade game that is loosely based on the 1976 arcade game Sea Wolf, where you are the submarine at the bottom trying to shoot the ships down from the top of the water. There are various sized ships, running at different speeds. There are 4 screens in all; the first is just the travelling ships, the 2nd adds mines, the 3rd adds the ships ability to drop depth charges, and the 4th combines both mines and depth charges. You are allowed up to 4 shots on the screen at once, and then you have wait for them to detonate to reload. You also have to shoot 40% or more of the passing ships within the time limit (60 seconds) to make it to the next level.
This game supported the Spectrum Projects SC-01 Voice Pak for speech; I am not sure if it worked with Radio Shack's Sound Speech cartridge.
