A Call of Duty: Black Ops Cold War bug granted this player thermal vision for the duration of their match, giving them a major advantage in-game.
In a video posted to the Black Ops Cold War subreddit Thursday, u/bryanhun64 began as a gunner in an attack helicopter. By the time they exited that scorestreak, they had already earned another. As soon as they could, they called in their gunship.
Their character opened the laptop through which they would control the gunship, and their vision adopted the black and white thermal of the gunship, but then the character immediately closed the laptop. The thermal vision persisted, allowing bryanhun64 to see enemy players highlighted in bright white even through smoke.
The match ended not long after the glitch took place, but the advantage it provided was clear. What's less clear is exactly why the glitch took place, but bryanhun64's not complaining.
