"Sly 2 Band of Thieves is a PlayStation 2 video game by Sucker Punch and SCEA released in 2004. This title is a sequel to the game Sly Cooper and the Thievius Raccoonus and part of the Sly Cooper video game series.
The sequel has a variety of changes, particularly in level design, in which the ultimate goal, a "vault," occurs not per level, but per "world". Also, it takes more than one hit to kill both the Sly and the opponent. Other changes include the ability to control not only Sly, but also Bentley and Murray, who are given more skills as compensation, able to do much more than their more limited persons in the previous game. However, Sly remains the central focus and character despite these changes to character roles. Finally, new skills can be bought at a 'safehouse', as well as being unlocked by opening safes hidden in each world."
