Sleep darts are form of gadgetry utilized by Bentley in the Sly Cooper series, starting with Sly 2: Band of Thieves, that allow him to knockout guards with ease by placing them in a sleep-like trance.


Sleep darts can be used by opening the Binocucom (click R3Button), then using R1Button to fire a dart. If a guard is hit, they can be taken out with a single bomb with TriangleButton.

Sly 2: Band of Thieves

In Sly 2: Band of Thieves, during the events of The Predator Awakes, Bentley used them to lure Rajan into watermelon in order to steal his blueprints and also to listen in on The Contessa in order to discern the location of Sly and Murray during their time in her rehabilitation prison.

Sly 3: Honor Among Thieves

In Sly 3: Honor Among Thieves, Bentley attempted to use these to sedate Inspector Carmelita Fox when she was possessed by the Mask of Dark Earth, which only made the situation worse, by causing Carmelita to grow even larger. He also used them to light the fireworks on pinwheels, in order to get to the Panda King.

Sly Cooper: Thieves in Time

In Sly Cooper: Thieves in Time, sleep darts are not available from the beginning of the game, but are purchasable later. They are used in much the same way as they are in previous games, though since there are many more varieties of darts, they have a lesser role.



  • In Thieves in Time, the currently equipped dart is also the currently equipped bomb, so after using a sleep dart, the ammo type must be changed from sleep to explosive in order to get the same effect as in Sly 2 and Sly 3.
