Head across the walkway and you will come outside under the bridge. Hop down on to the broken catwalk there and continue up along the diagonal girders to the office at the top. Kill the crab there and the bridge will start to shake as a train goes across it. Make your way across the next set of girders and climb the ladder there to the office. Grab the crossbow weapon there and head out and then pop the two combine soldiers on the top right. Head up the next ladder and walk across the catwalk and across the girders some more to reach the other side of the bridge. Enter the room there and follow the stairs down and out. Kill the combines there and enter the structure and go out the door on the right. Follow the ladder up to the catwalk and enter the doorway to come to some stairs. Head up and enter the room with two combines behind a field.



Use the manipulator to press the button on the left side and then when the shield is down, press the button on the right. Now a gunship will show up and some more combines. Make your way back out of the building and back to the girders. You’re going to take some fire from the ship, but you need to get back to where there were rockets to take it down. When you do, continue along the girders and all the way back to your buggy. Hop in it and drive up the hill to get on the train tracks and turbo boost it to the right. Hurry up and pull over to the left as soon as you can since a train will be barreling towards you at a break neck speed. When you go left, continue going left and use the ramp there to enter the tunnel.



Sand Traps

As you enter the tunnel, you’ll come to a car pile up and a load of zombies. Hop off the buggy and take them all down. When they are toast, clear the way with the manipulator and drive on through. Continue down the road and you will come to a house on the right. Clear it out and continue to the next roadblock. Clear it out of combines and keep bootin down the road using the left side grass area to get over the first break in the road and then the right side to get past the overturned tanker. Just past there will be a set off houses and a gate blocking the road. In the house will be a little contraption that takes three car batteries and it will then open the gate. There will also be a gunship that flies in and drops off some soldiers.



Take them down and then grab the two batteries from the grey car to the left of the house and another under the bathtub to the right of the house. There is also a third battery inside the house on a mattress. Place the batteries in their spots so the lights turn green and the gate will open for you. Drive through and enter the next tunnel. When you exit, you’ll come to a few more houses but these are where the resistance is holed up. Park your car in the garage and you’ll have a few fighters along side you as drop ships fly in to drop combines. Take everyone out as they come and eventually you’ll be told that there are rockets in the light house. Head for it and climb up to the top and grab them. Take down the gunship and a fighter will come up to meet you. He’ll lead you down to the lower level and open a door for you to follow a path.

Exit out through there and make your way left across the rocks and into a cave as a drop ship flies away with your buggy. As you reach the other side, you’ll meet a guy who will tell you about the sand and the antlions. Make your way across the rocks and eventually you’ll be able to go left. Go left until you reach the wide open area and then start going left again. You supposed to be jumping from anything to anything just not touching the sand, but I basically just ran my butt off through the entire area and then stopped when I came to the explosive barrels and let them have it. When you climb up the rock there to look over the next area of beach, there will be bodies and debris all over.



Drop down and when you hit the ground, the big momma antlion will appear with some smaller ones. Take her out using rockets if you have them and explosive barrels. Other than that, just fill her will anything else you have until she drops. When she does, a Vortigaunts will appear and tell you about the Pheropods. Pick it up from her corpse and you will now be able to control the ant lions. Continue to follow the Vortigaunts along into the resistance base and he will show you how to use the bug bait.

Run across and jump to the other side and go through to the two zombies at the fire. Kill them and run up the ramp that falls and continue up the ladder to the catwalks. Hop across to the grass ledge and continue up the grass ledge to a pipe. Kill the zombie there and follow it along till you reach the ladder.
