than its normal top speed. Boosts are achieved by driving over boost pads scattered across the tracks, pumping the gas at the starting line, and holding the gas button at the right time when being reset on the track. Another technique used for boosting is the "power slide". To execute a power slide, the player holds down one of the hop buttons while steering. While sliding, a curved "boost gauge" appears next to the player's kart. When the gauge goes from green to red, the player presses the opposite shoulder button to obtain a boost. The higher the boost gauge goes, the more powerful the boost will be. Racing modesCrash Nitro Kart features 6 racing modes: Adventure, Race Time Trial, Lap Time Trial, Quick Race, Team Race and Cup Tournament. Some modes are free-for-all, while others can be played as a team. The "Adventure Mode" is a single-player game in which the player must race through all of the tracks and arenas in the game and collect as many Trophies, Relics, Boss Keys, CNK Tokens and Gems as possible. The objective of the Adventure Mode is to win all the races of the five different worlds and win the freedom of the playable characters from the tyrannical Emperor Velo XXVII. The hub world of the game is Velo's Coliseum, from which the player can access any of the five other worlds through special gates. Most of these gates are initially locked; the player must complete the races of one world to gain access to the next world. When inside a world, the player may access a race by driving the selected character onto a "Warp Pad". By winning a race, the player will receive a Trophy. When the player receives all three Trophies in a world, the player will be able to race against that world's champion, who acts as a boss character. If the player manages to defeat the world's champion, the champion will relinquish a World Key. This allows the player to engage in the special modes of that world and enables access to the next world. The special modes of each race consist of the "Relic Race", the "CNK Challenge", the "Crystal Arena" and the "Gem Cups". In the Relic Race, the player must race through a track alone and complete three laps in the fastest time possible. To aid the player, "Time Crates" are spread throughout
