Grand Theft Auto V 100% Gold Medal Walkthrough \ Guide in HD
Easter Egg N. 2 – Bigfoot Sighting
During the mission “Predator” given by Trevor, you need to hunt down the O’Neil brothers in the woods of Cassidy Creek using an advanced sniper rifle with the thermal scope.
If you aim to the down right corner, you can spot Bigfoot standing still. He will immediately disappear after he has been spotted, and if you try to shoot him, nothing happens.
