You'll acquire a dune buggy, which is faster and more robust than the hovercraft. It comes equipped with a mounted gun, similar to the hovercraft, but also has a boost function. Use the buggy to traverse the long stretches of Highway 17. You'll encounter Combine checkpoints, turrets, and Snipers. The buggy is essential for covering ground quickly and for engaging enemies from a distance. Remember to keep an eye on its health and repair it at designated stations or by finding spare parts.
