Call of Duty 5 easter egg!

on the level hard landing,after your boat crashes and you call in rocket strike, go to the right corner of the beach there will be a puddle, stand in it.then go to the middle of the map and stand in the puddle there. then go to the left pool by the barbed wire now stand there wait for about 3-7 seconds, the screen should start shaking and 4 lion statues will apear, in their mouths are ray guns these are very affective as long as you dont shoot so close.You can take these ray guns from their mouths if you swap weapons. I know it is for pc but I am not sure about other systems.
