so Tunguska is the first one that i need to get started . right ?

That is the first game in the series, yes.

great - what about a walkthrough ??? how do i get it ?

GameBoomers has two walkthroughs, one of which is here.

thanks for that info. so I could just print it out , right ?

I don't see why not.

thanks for the info , BTW is this a long game ?

It's been many years since I played it, but my recollection is that it's a good length. It is certainly not a short game.

thanks for that info. have a good day. looking for a much shorter game than that . what do U think of Traitors Gate ? or black mirror 2 .
