The main mode sees players earn reputation points in various events to gain the interest of sponsors who provide them with new vehicles. Flashbacks return from Colin McRae: Dirt 2, which can be used up to five times in any difficulty, but cost reputation points to use. A new gymkhana mode puts players in obstacle courses, challenging them to perform various tricks to earn points. Featured in the game are various party modes, involving events such as smashing wooden targets, spreading a zombie infection, and capture the flag. Other new features include a Hardcore mode which limits players to the cockpit view with no assists, the appearance of rain and snow, and the ability to upload replay clips directly to Youtube.
