How to Unlock Nitrous Oxide in "CTR"by John GrossmanUpdated September 22, 2017
Nitrous Oxide is one of the characters in the Sony PlayStation racing video game, "Crash Team Racing." This video game features most of the characters of the Crash Bandicoot series. As in the other games in that series, the evil Nitrous Oxide is the main villain in "Crash Team Racing," and players must defeat him to win the game. It is possible to unlock Nitrous Oxide as a playable character by using one of the cheats the developers have added to their game.
Finish the game's Adventure mode and collect all platinum relics. In the Adventure mode, players must complete a series of races before finally racing against Nitrous Oxide. At the end of each level, players compete in a relic race which allows them to collect relics by breaking certain records. Platinum relics are the most difficult to obtain. Collect all of them and defeat Nitrous Oxide, the final boss, to finish the game.
Beat all of N Trophy's ghost cars in Time Trial mode. N Trophy is another CTR villain, and you can race against a ghost version of his car in Time Trial mode. You must perform this step in order, starting with track number 1, Crash Cove.
Beat all of Nitrous Oxide's ghost cars in Time Trial mode. You must again perform this step in order, starting with track number 1, Crash Cove.
Hold the L1 + R1 trigger buttons and press the Right, Circle, Triangle, Left, Down, Circle, Triangle, and Left buttons at the title screen of the game to finally unlock Nitrous Oxide as a playable character.
