After the boat crashes, call in an air strike on the specified location. Run up to the beach, and move to the right. You will find a small puddle at the right side of the beach. Stand in it briefly, then move towards the middle of the beach to find a smaller puddle. Stand in that puddle briefly. Move towards the far left side of the beach. Stand briefly in the puddle in the barb wire. After several seconds, the screen will shake, and you will hear strange voices. Four lion statues will rise out of the ground with alien Ray Guns in their mouths.

There will be a section where you will be asked to "Save Private Ryan". This is a reference to the critically acclaimed film Saving Private Ryan.

Successfully complete one of the following to get a Trophy.

Towards the top of the map is building with two windows that overlook the whole area. Note: Other players will try to get you.

Go into the house next to the burning house. Stand on a windowsill and face the side. You should fall on a ledge below.

Enter the burning house. Go up the steps and out the window in the same way to hit a ledge below.

Go to the building in the middle of the map (near the building on the far left). Go up the stairs. Turn left at the top and turn left again. You should see a wall you can climb over. Climb over it and you should be on a small ledge. This is a perfect sniping location. Also, if there is someone in the building already, you can climb onto the ledge from the outside, although this may require a few attempts.

At the bottom of the map you should see a building with a ladder. Climb the ladder to reach a good sniping location. It is difficult for people to get to you because the only way in is up the ladder.

Reach Level 32 to unlock Veteran mode, which is a Co-op mode with much tougher enemies.
