The Isis Adventure

Well I’m well and truly stuck in this club.....Love the Puzzle excellent build quality..Kinda wished that I hadn't moaned so much about waiting for it.

A quick question do you need the additional clues to open it the Puzz way?

If I stay in here much longer I will have to use the old "Rusty way" Where is Rusty?

The clue in the secret compartment is all you need,
I don't know if the extra decryption files would make it any easier.
That is assuming that I have got the equation right, I haven’t had a response from Puzz yet.

People keep mentiong the 'Formula' or 'Equation' - but where is this? I'm just about to order a Copernisis and would like to start work on the equations whilst a await delivery.

Or is it something that comes out of the clue drawer?

The equation is written in the secret compartment,
you have to figure out how to open that to read the clue/equation.
