Developer: Steve Beck

Steve Beck ran Beck-Tech, which programmed games for other publishers. The game filed under his name here is Save the Whales, made for 20th Century Fox around 1983: you steer a submarine and shoot the nets and harpoons a whaling ship drops on a pod of whales. It was meant to raise money for Greenpeace but was never released, and the prototype only turned up in 2002. Beck-Tech also developed Ghost Manor for Xonox.
