Heat vision

ive heard a little bit about something called hear vision, some people say you can use heat vision. Does anyone know whether there heat vision can be used in Halo 5 guardians? But even if there was, wouldn’t it be in the first level Osiris?

There is no such thing in halo 5.
but its in halo 4, its called Promethean vision.

Ohhhhh, yea i know what that is
