by the alarm or hide for several seconds until the alarm resets. The game uses a dynamic music system that changes depending on the state of alarm in the area: the music will increase in volume and pacing when Sly attacks or is detected, and then will quiet down as the disturbance goes away. Each sub-section of a lair contains a number of clue bottles that, when collected, allow Sly to access a safe in the level that contains a page from the Thievius Raccoonus. These pages grant Sly new moves to aid in movement, stealth, or combat, such as creating a decoy or dropping an explosive hat. Defeating each of the bosses also gives Sly moves, and these abilities are typically necessary to pass later levels. Coins are scattered about the levels and are also generated by defeating enemies or destroying objects. For every 100 coins collected, Sly gains a lucky horseshoe that is the color blue and when you have two horseshoes, it turns to gold. It will allow him to take extra hits, or if he currently has one, an extra life. If Sly collapses and loses a life, the current sub-level will be restarted or at a special "repeater" that acts as a checkpoint; if the player loses all of Sly's lives, they must restart that bosses' lair from the beginning. Besides the regular gameplay, there are mini-games that include driving levels (based on Murray), shooting levels to protect Murray as he ascends certain levels, and a cyber-tank game representing a hacking attempt by Bentley. One notable boss battle includes a rhythm-based sequence similar to Dance Dance Revolution. Levels can be returned to at any time to gain additional coins or to seek out special moves. When a level is completed, all of the clue bottles are collected and the secret move is found, the player can then attempt a "Master Sprint", a timed sprint through the level to try to beat a set time. The player can unlock additional artistic content by completing all the levels in this fashion. For each level that has the "Master Sprint" completed, a developers commentary for that level is unlocked. Plot Sly Cooper comes from a long line of master thieves (the Cooper Clan) who only steal from other criminals, thus making them vigilantes. The Cooper family's heirloom, an ancient book named The Thievius Raccoonus, records all the secret
