So I have a theory to solving the Mt. Chilliad mystery, whilst I was experimenting I may have stumbled across what might be the answer... I'm not going to explain my the full story just yet until I have confirmation, but from what I have read I don't think this has been attempted yet.

As I was exploring my idea 2 of the 'x's from the mural map led me to 2 mobile numbers. (THIS IS WHERE YOUR HELP IS NEEDED!) I tried calling them both and got the same message twice. I am yet to 100% the game on next gen, which is why I believe that after you have achieved 100% the message may be different, unravelling a new clue to unlocking the jetpack.

So, people who have 100% on the game if you could try my method, maybe we will be 1 step closer to solving the mystery. Here's what I want you to do:

• First number to call - (323)-555-0189

• Second number to call - (323)-555-0161

Now if nothing happens I have another idea, try calling them again, this time as Michael. If that fails then lastly, try calling them once you have completed Michaels murder mystery on next gen and have bought the theatre.

I would greatly appreciate it if someone could test this whilst I work toward completing the game. Let me know what results you get and I will share my full theory!

Thanks.
