Tanks... That is all.
Why Cosmo Tank was never expanded on, and made into a full blown franchise is completely beyond me. Although a simple tank shooter, it was a fantastically fun game, which provided me hours of enjoyment in my childhood, and still does to this day. Blowing up five Giant Crabs at once with a bomb makes for one of many wonderful experiences in what I find to be one of the greatest portable action games of all time. Let’s all pray for a console, or even better, a DS/PSP title in the future! Happy hunting!
