The first Lone Wolf Gamebook I have ever read was The Caverns of Kalte and I always wanted to see a videogame porting of one the best chapters of LF Saga. Unfortunately, even if a game was planned (HCP for C64 & ZX Spectrum), it never actually happened and the only official visual is represented by the advertisement below.

The advertising above, even if visually interesting, it wasn't revealing anything about the game itself. Luckily I managed to find a more accurate ad appeared on the Lone Wolf Club Newsletters (Summer Special 1985).

The promise was quite inviting: 3D animation and graphics, unique combat system and multidimensional plot lines (?); the possibility to order the game was a quite unusual choice especially when probably neither a playable preview nor a demo was available. Anyway a small note at the bottom of the page was remarking that almost 30 days were needed for the delivery. What happened to this title so?
Time for more digging.
And yes, here's my copy of Caverns of Kalte.
One thing I've discovered reading the English version of the Gamebook, was that for unknown reasons, in the Italian version, Vonotar (the main villain of Kalte) was renamed as Vonatar. A (repeated) typo or just a phonetic choice? Who knows why.
