MX vs ATV Untamed

The game encompasses several modes: Motocross, Opencross, Supercross, Supermoto, Endurocross, Free Ride and Minibikes, among others. The player has a relatively wide choice of vehicles, from monster trucks, to trophy trucks, to ATVs to motorbikes. In some modes, gameplay takes place over two motos, or qualifying events. The player's finishing position in the first moto determines who gets gate choice in the second moto.

The player's finishing position in each moto determines how many points he or she gets. The goal is to finish the weekend with the most points. Additionally, in some modes, the player can participate in a short practice race, which can help players become familiar with the track and the vehicle prior to the two motos. Setting the fastest time in practice gives the player first gate choice for the first moto.

Untamed was first announced by THQ during E3 2007. THQ sought to bring Untamed to a wider variety of platforms in order to "deliver unique experiences that capture the franchise's strengths and maximize the fun gamers have on their system of choice", and commissioned as many as three developers to work on its various versions. The series' main developer, Rainbow Studios, developed the PlayStation 3 and Xbox 360 versions, while two new firms Incinerator Studios (a THQ subsidiary) and Tanatalus Media were each assigned to work on two other platforms. Incinerator Studios, the developer of the Wii and PS2 versions, decided to spend some more time developing the Wii version to best implement its motion controls, resulting in that version releasing later than all the other versions in North America and Australia.

Untamed was originally planned for an early 2008 release. Ultimately, it was first released in North America in time for the 2007 holiday season, and eventually became available for PAL territories the following March, with all versions releasing simultaneously in Europe.

MX vs. ATV Untamed received "mixed or average" reviews, according to review aggregator website Metacritic.

GameZone gave the Mobile phone version a score of six out of ten and called it "a better-than-average mobile racer", but said it was "a few gallons short of a full tank".
