To get this achievement you must purchase the new perk called "Who's Who" (Cost: 2000) but note you must turn on the power first. I found this machine in the elevator to the left of the spawn door (not beside the M14, its an immediate left). It can also be found in the elevator to the left of the PDW below the spawn (beside the window where you can see the Dragon).
Once you purchase the perk, you must down yourself and you will go into 'Ghost mode' (or as Badonkadonk115 puts it 'Limbo state'). In this mode you will have only your pistol. You must go over to where your body is and revive yourself before you bleed out. Don't worry about spawning too far away, you'll spawn fairly close to yourself going into Ghost mode. Note that you can still be attacked
while in Ghost mode, so do it when there are no zombies around. You have approximately 45 seconds to perform the revive, or else you will miss out on the achievement as well as retaining all of your perks and weapons if you bought any.
