Overview
is a side-scrolling hack-and-slash action game produced by Sega and originally released as an arcade game in 1989. It is the second and the final arcade game in the Shinobi series, following the original Shinobi itself. The player controls a ninja aided by an attack dog, who is fighting to save the city from a terrorist organization.
Shadow Dancer was the first game developed for the Sega System 18 arcade board hardware, and its generally well-received home versions were released for the Master System console and several home computer systems in 1991. A loose adaptation titled Shadow Dancer: The Secret of Shinobi was released exclusively for the Mega Drive/Genesis in 1990.
Gameplay
The play mechanics of Shadow Dancer are similar to these of the arcade version of the original Shinobi. The controls and almost all of the player's moves from the original Shinobi are present here as well.
The biggest change is the addition of a canine companion, Shadow, that follows the protagonist around. When the dog barks towards an enemy, the player can sic the dog on the enemy by pressing the attack button while crouching, allowing the player an opportunity to attack the enemy while it is being bitten by the dog. However, if the player takes too long to attack the bitten enemy or the enemy has a strong defense, then the dog will be hurt and turn into a harmless pup. The dog will then remain in pup form until the player acquires the next time bomb or finishes the stage.
