This one needs to be done in squad mode, but it's really simple. After you get downed, you can run through the map to find a Respawn Station (it looks like a triangle and the near ones are marked on your HUD). Get close to one of them, press
and you will enter it. Then, you need to wait for a teammate to find the Station and interact with you. Now that you are back from the dead, just kill someone and the achievement will pop.
