There are a few headcrabs inside that can be smashed with various objects. If you choose to enter the house ahead, go in through the basement storm door on the right side. This tower is called a thumper and it repels the ant lions, so stick near it to stay safe. Head to the left towards the house and the odd tower. Get out of the buggy and grab everything in the area, then get back in the car and go through the tunnel.At the other end, take a right down the rocks and back onto the beach.
At the top, there is a shack surrounded by supply crates. Take a quick right and go up the hill to meet up with the road again. At the top of the incline, hit the turbo and jump over the embankment to the roadway.
