Lost Easter Egg
If you go to the top left corner of the map you see an island shaped like a square. If you fly a plane over the island your plane will explode causing you to parachute down to the beach (if over it). You will see a search sign on the beach with an arrow pointing to the jungle. Go into the jungle and you'll find the hatch from lost. It is even said by people that you actually can hear the smoke monster in the background.
