Can you find Big Foot in GTA V? If yes, what mission, which character, and where do I have to be looking to see Big Foot?
There are two missions that have bigfoot in it:
The Last One
The first mission,
Predator, is the mission where you snipe the O'Neil brothers in the woods.
This video shows bigfoot's location in the Predator mission (Bigfoot section at 0:44):
The second mission,
The Last One, is a Franklin "Strangers and Freaks" mission.
