Visually, it contained realistically shaded enemy characters, and an eyepopping scrolling background which went beyond what most arcade gamers had seen at the time.

Xevious is an arcade game designed by Masanobu Endoh, one of Japan's most respected game creators and the mastermind behind Namco's later arcade hit of '84, The Tower of Druaga.
