Alrighty pretty straightforward and simple, your main goal of this chapter is to rescue Basso. Once that happens it will be onto cracking "The Great Safe". For anyone who is getting stuck on this part, you probably are doing the same thing I was at first...with the combination 30-11-98.
You would think you would enter 301 on the first set of dials...but as of right now that doesn't work. What you actually need to put in is 319 which is the first number in each combination. Weird I know...then finish the chapter and don't forget that the last 3 digits will be 018. Hope this helps for anyone who was having problems with the safe.
