Gradius II for NES

Gradius II has kept the gameplay from the original game, but infused it with enhancements brought from the spin-off, Salamander, and the Japanese arcade release of Life Force. This is primarily evident in two of the weapons configurations that are selectable.Another first in the series was the inclusion of the "boss rush" (also known as "boss parade" or "boss alley"), levels designed entirely with only boss confrontations.
