Bigfoot Easter Egg

During the "Predator" mission, you will chase two enemies through the forest. Eventually, you will reach a yellow ring, and it will switch to Michael in the helicopter with a sniper rifle. Use the rifle's thermal scope, and aim down and right to see a slightly fatter thermal signature in the forest. Switch off the scope to get a good look at Bigfoot. Note: Bigfoot only appears for a short amount of time. Thus, you need to find him quickly.
