Uncover the Secrets of GTA V with the Vintage Graphics Filter and Bigfoot Hunting Mission

To access the Vintage graphics filter, return to the game on the PlayStation 4 from the PlayStation 3 version. Complete the main storyline, and while playing as Michael, find the four murder mystery clues written on various walls in Los Santos. You will hear a sound after each clue is viewed. Take the submarine out into the ocean off the west coast, and then swim down to the bottom with the scuba gear to find a drowned woman chained to concrete on the seabed, near a sunken ship. Next, go to Richard's Majestic film studio after 9 p.m., and step into the yellow mission circle. While in the office, look at the letter on the desk. It will lead you to the mineshaft. Use a gun with a flashlight to navigate your way to the bottom of the mine to find Issac's corpse, which will be added to your contacts. Select that contact to apply a black and white noire filter to the graphics.

To unlock the Secret Bigfoot hunting mission, achieve 100% completion in GTA 5 to unlock "The Last One" secret Strangers and Freaks mission for Franklin at Mount Chiliad. The special mission requires you to catch a Sasquatch by chasing him through the forest.
