About 2 months ago I remember hearing that the Ninja perk did not work on Heartbeat Sensors, I remember using the Ninja Perk and dying by someone with a heartbeat sensor but I could never notice if I was on the radar or not, I used a silencer but I was moving. Anyway I am thinking about setting up a Ninja Perk class and was wondering if the perk works or is it still messed up?

It's always worked.

I think if you use Ninja Pro, your footsteps obviously cannot be heard, and you can not be detected by the heartbeat sensor, but i myself have not figured out if you still show up on the radar if you fire a weapon? Silenced or not.

If you fire a weapon you show up on radar, but you're never suppose to show up on heartbeat sensor even if you fire the weapon
