Drive off in a vaguely right direction towards the water 3 follow the dark brown path that will eventually curve left and go up a hill.
(Take note that there are an infinite number of these). You must do this quickly or else you will be eaten by the antlions that spawn. Quickly get out, select the gravity gun, and flip the buggy over by using the primary fire button 2. You will incur some damage, but don’t worry about that. You will be lowered to the ground below, but in the process the magnet holding the buggy fails and the car drops. The buggy is also equipped with a handbrake and turbo the game will prompt you of these keys every time you enter the buggy. Fire it with the primary attack button and charge with the secondary. The mouse is used to look around and aim the tau cannon (basically the gauss gun from Half-Life 1). The buggy drives with your direction keys: straight goes forward, back goes in reverse, left turns left, and right turns right.
Approach the dune buggy in front of you and get in by hitting your “use” key. On your right will be a few health kits 1. Open the door and step out onto the pier. In areas where it is more obscure, there will be better directions and sometimes a picture to help guide you. Because of this, the directions will be simply to follow the path. Note: In this level, it is obvious the direction you need to head in, for the most part, because there is only one way to go.
