Egg-Stra Devastation Achivement and Egg locations.

This one is the easiest to find and right near the spawn point on one end. You should see this temple thingy.

Look inside it and you should already see it.

Shoot it.

Right. This one was a bit tricky to find. Go to the far side of the ship. (Which direction shown in image)

Now look down.

Shoot it.

This one. THIS ONE. I hated this one. Tricky little so and so.
Anyway. Go to the tent dome with the giant meteor thing in the middle

Go up to it and look right in the crack along side the meteor and shoot the dang thing.

Oncce again right next to a spawn. Go to the car/bridge end of the spawn to this area.

Now go to the edge and look at the cement bit of the bridge.

It's right down there in the corner. Sometimes blocked from view by waves.
