Obscure the vision of your enemies for a hasty getaway.
― In-game description[src]
The Smoke Bomb is a purchasable power-up used by Sly Cooper in Sly 2: Band of Thieves, Sly 3: Honor Among Thieves and Sly Cooper: Thieves in Time. It is used to obscure the vision of his enemies in order to easily escape. It uses a small to medium amount of the Gadget Meter, except in Thieves in Time, where the gadget meter is automatically recharged.
To activate the gadget, Sly stops and taps the end of his cane into the ground, creating a cloud of smoke. In Sly 3: Honor Among Thieves and Thieves in Time, the gadget is upgraded so that he can simply throw the Smoke Bomb into the ground while still in motion. In Thieves in Time, it is performed by pressing . If it is deployed very close to an enemy or breakable object, it will hit them, causing the equivalent of one cane-swing's worth of damage.
In the "Cops and Robbers" mini-game in Sly 3, the Smoke Bomb is one of four power-ups that Sly can use against Carmelita. It covers a larger range than the usual version and will cause Carmelita to momentarily stop pursuing Sly and cough if she is near the smoke.
The Flash Bomb is an upgrade of the Smoke Bomb, available only in Thieves in Time. It costs 600 coins. It has a larger area of effect and longer duration. Enemies who are blinded by it will not check Sly's last known position. If it is deployed very close to an enemy or breakable object, it will hit them, causing the equivalent of one cane-swing's worth of damage.
- In Sly 2, using the smoke bomb will allow the player to perform the Stealth Slam on an enemy, even if they are facing you. In Sly 3, the player will have to knock them unconscious before doing the attack.
- In Sly 2, the smoke bomb will not work on Carmelita during "A Friend in Need," when trying to escape from her.
