1 Introduction
This pinball machine was manufactured in 1987 by a Spanish company, Universal de Desarrollos Electronics, S.A. Their various trade names were Unidesa/Cirsa/Stargame.
It is horror-themed and has both 2 and 3-ball multiball.
The boardset is unique and the playfield parts are as well.
The manual for the game is in Spanish. The available scans of the manual available on the internet (see the manual on IPDB) are not good quality and there are some mistakes (to be pointed out below).
