Bolt multiplier

The Bolt Multiplier is a feature presented in all Ratchet and Clank games. It's earned after the game is beaten at least once. After the feature is available, for every enemy Ratchet defeats, the bolts earned are multiplied by a sequene of numbers, starting in 2 and ending in 20. Notice that, in Ratchet and Clank: Up Your Arsenal, due to the box that multiplies all bolts times 2, the maximum multiplier possible is 40 times.
