Flashbang grenades are meant to disorient your foes. Instead, Call of Duty: Black Ops 6 players have discovered that using them to blind your teammates will net you 15 XP. It's a farming trick that promotes bad cooperation.

YouTube streamer Expel posted a video of the XP exploit on X, adding that throwing flashbang grenades at allies "gives you XP" and "do with this information what you will." The UI text on screen states, "Flashed Enemy," so it seems likely this is an unintended benefit for being a terrible teammate.

Grinding for progression and prestige is a core tenet of Black Ops 6, on top of the rewards and unlockables in multiplayer. As such, there will always be players looking for easy ways to level up. For instance, the original Destiny famously had a loot cave for farming a decade ago, when people mindlessly shot at a cavern for hours on end. That exploit was addressed but ended up leading to an in-game dungeon acknowledging the loot cave.
