And if it is in fact not in the game I demand a solid explanation as to why the jetpack figure is on the Mural .
Which Rockstar Games will never give us. Just like Bigfoot in San Andreas. The same about giving hints, they just don't do it.
R* said there was no bigfoot in an interview.
Well, some higher up guy did an interview about it and other eggs and said pretty boldly, "No".
Maybe they didn't confirm/deny anything in the time frame that you felt was acceptable but, they have addressed the eggs from S.A., including Bigfoot.
