Racing Limits is an extremely popular mod for Halo 3. It adds a variety of new features to Halo 3, including changing camera angles, new weapons, better aim with consoles, and many more small improvements. However, what really makes this mod so popular among Halo fans, is that it allows you to play the game in the high definition quality that was made possible with the release of the Xbox version of Halo.
Unlike most mods, which update one aspect of the game (such as the distance you can drive), this mod focuses on changing various aspects of the game itself, in order to make playing the game much more exciting and fun. The core of the mod is an application called the "Races" app, which allows you to select various official Xbox races, and choose between them to compete in them. With the help of the Xbox Kinect device, you can use your hands to control your vehicle, and the racing limits only take place if your vehicle breaks any of the invisible barriers around the track. For example, you wouldn't be able to drive your speedy Lamborghini into a pile of rocks and turn it into an unstoppable superstar, if you didn't know exactly what you were doing.
You can download the racing limits app from the Xbox Marketplace, but please try to download it from a reliable source. Sometimes download sites may install viruses or malware onto your PC, so it's always best to download the app from a legitimate site. If you're worried about your safety while using the app, then you can always go into "Settings" and then click on "Behavior", which will prevent other players from being able to tamper with your device, or modify any of the setting data. Please remember that you are solely responsible for the use of the racing limits app, so always exercise extreme caution when using it.
