Quick Boom is a medal kickback available in Uncharted 3: Drake's Deception. When activated, the Quick Boom kickback gives the user an additional grenade, and all grenades explode on contact with a yellow indicator. It costs 10 medals to activate and has a duration of 15 seconds. It is unlocked when rank 15 is reached. Originally, Quick Boom had a duration of 20 seconds and it costed 7 medals, but this was later changed in Patch 1.03 after the community's request.
