FlatOut 2

The sequel to 2004's FlatOut, FlatOut 2 is themed more on the street racing/import tuner scene than its predecessor. A notable change is the tire grip; players can take more control of their car, worrying less about skidding in tight turns. The game has three car classes: derby, race, and street. An enhanced port was released in 2007 for the Xbox 360 and Windows as FlatOut: Ultimate Carnage. A PlayStation Portable port of Ultimate Carnage was released as FlatOut: Head On in 2008. The same year, a Mac OS X version of the game was released by Virtual Programming. An update for the PC version was released in July 2024, that implemented Steam Workshop support, improved support for the Steam Deck and added various quality-of-life improvements. In 2023 Virtual Programming released the game to the Mac App Store with the game being updated from the original 32-bit Mac OS X version to a 64-bit version compatible with both 64-bit Intel and Apple Silicon processors, requiring macOS Big Sur or newer.

The ragdoll physics have been greatly improved from the previous game. During the race, the driver may be thrown out of the car if slammed into a wall at a high speed. In the numerous stunt minigames, players can shoot the driver out of the car in order to complete objectives like knocking down a set of bowling pins, hitting the designated spots on a dartboard, scoring a field goal or flying through flaming hoops. Players must use 'aerobatics' to control the driver in-flight, but overusing it will increase drag, which will slow the driver down and possibly prevent them from reaching the designated target. If the driver falls short of the target, players can use the "nudge". This gives the driver a small upward boost and slightly reduces drag. In the Stone Skipping Stunt minigame, the players must use nudge just as the driver hits the surface of the water to skip the most efficiently and reach the furthest.

FlatOut: Ultimate Carnage is an enhanced port of FlatOut 2 featuring new gameplay modes, soundtrack and graphics as well as at least two new cars. It was known earlier as FlatOut: Total Carnage. FlatOut: Ultimate Carnage was released on July 22, 2007, in Europe, on August 1 in Australia, and on October 2 in North America for the Xbox 360. The Microsoft Windows version was released through the Steam network on August 26, 2008, and in stores on September 2. There is also a handheld version of the game for the PlayStation Portable called FlatOut: Head On, which was released in Australia on March 12, 2008, in Europe two days later, and in North America on April 4.

Ultimate Carnage introduces a Carnage mode, a challenge series type of mode, which includes 36 challenges among stunts, demolition derby deathmatches, carnage races, and beat the bombs. The cars are more detailed than previous games in the series, employing the latest in dynamic lighting and shadow technology, and a greatly enhanced damage and physics engine where each car is made of up to 40 separate destructible parts. The single player game supports up to 11 other AI-controlled cars in each race. A new multiplayer format is also included; this runs on the Games for Windows – Live system which requires the user to either sign into own Xbox LIVE or Games for Windows LIVE Gamertag, or sign up for one for free. The LAN function is not available in FlatOut: Ultimate Carnage, unlike the previous two FlatOut games for Windows.
