"3 player kill streaks earn a random perk (3 max). Expires upon death."
— Gun Perk Description
Gambler is a LegendaryGun Perk that appears in Call of Duty: Infinite Warfare, found upon Legendary weapon variants. It awards the player a random perk after every 3 kills up to a maximum of 3 perks (or 9 kills) per killstreak, similar to the Specialist Strike Package from previous games. A player can also obtain a possible third perk for a certain tier with Gambler, if the player earns two or more with a single killstreak or has two perks in a certain tier from the start.
In Zombies, Gambler would give the player a random Candy Perk after every 75 kills up to a maximum of 5 perks (or 375 kills) without being downed.
