Ninja Princess opens with a short cutscene of the princess Kurumi getting carried away in a palanquin - her castle Kanten has been seized by the traitor Zaemon Gyokuro, who obviously wants to get rid of her. But she escapes, transforms into a kunoichi and sets out to regain her home. Even though it's basically all about running around killing people with knives, Ninja Princess clearly wants to be a girly game. Everything is bright and colorful with cartoon-like proportions, and when Kurumi gets hit by an enemy, she just sits on the floor and starts crying. It's hard to resent the game its stereotyping, though, cause it's just cute as a button - no surprise here, after all the graphics were designed by Flicky artist Yoshiki Kawasaki and Reiko Kodama of Phantasy Star fame.
Desert Assault (known in Japan as Thunder Zone is a 1991 run and gun arcade game by Data East. In this arcade game, up to four players control four soldiers holding machine guns and other projectile weapons, while fighting their way through the terrorist arsenal to take control of the Persian War.
Players manipulate a four-way joystick and a Speed button to control the direction and acceleration of their train as it rumbles down the track to the tune of "I've Been Working On The Railroad". The basic idea is to keep from running off the track. To get really big scores, though, players must drive locomotives into the passenger stations and pick up the waiting strap-hangers. There is even a bonus station that can only be reached during a limited time period. The faster the player gets to the special station, the more bonus points he or she collects (from 1000 to 5000).
