<P> A Titan's durability depends on its size; larger Titans will take more effort to defeat than others and a few are immune to Crash's attacks . To defeat them, Crash has to jack a smaller Titan to fight them . On defeating the larger Titan, he can dismount the Titan he previously jacked and directly jack the larger Titan . The dismounted Titan will then be destroyed . </P> <P> A player using a second controller can join the game at any time in the form of a white - furred version of Crash known as "Carbon Crash". The second player appears in the first player's backpack, and can usually enter or exit the pack . However, the second player has to stay in the backpack if the first player is in mid-air or climbing a wall . This method of play is useful for overpowering enemies and collecting Mojo faster . There are two modes of co-op play; in "Leapfrog Mode", the players swap control each time the front player jumps, swings, or slides, while in "Piggyback Mode", each player is equipped with their own backpack and can hide in the other player's backpack if the action becomes too intense, such as when jumping over a chasm . </P> <P> The setting of Crash of the Titans features twenty levels . Each level is referred to as an "episode", and each has a distinctive subtitle that is usually a reference to popular culture (such as "The Blizzard of Claws"). Like the first Crash Bandicoot game, episodes must be played in order, although the player can replay any episode that has been completed . The game moves through five major themes taking place on Crash's homeland, the Wumpa Islands . The story starts in the jungle near Crash's residence and leads to an ancient temple . Later in the game, Crash travels through a wood - cutting and mining area and a land flowing with lava that features giant steel mosquitoes sucking minerals out of the ground . The next few episodes take place on an artillery - bombarded beach, where Crash infiltrates Doctor N. Gin's missile factory, which resembles the Statue of Liberty . The penultimate area is a gigantic tree located in the middle of the island . This tree holds up an entire house owned by Uka Uka, one of the major antagonists of the series . The final moments of the game take place in the antagonist's Liberace - style lair, and finally inside the Doominator . </P> <P> Nine characters from previous Crash Bandicoot titles star in the home console version of Crash of the Titans, all of them given a new modern "punk" style that is distinct from other and Japanese video game characters . The protagonist of the game, Crash Bandicoot, is a bandicoot who must defeat the main antagonist Doctor Neo Cortex and use the Titans against each other while collecting Mojo to upgrade his fighting techniques . Aiding Crash is Aku Aku, an ancient wooden mask who acts as a shield, a skateboard, and a weapon . He can also help Crash jack Titans . Crash's other two allies are his genius sister Coco Bandicoot and his muscular older brother, Crunch Bandicoot, who is absent in the Nintendo DS version . </P>
