Ectoplasmic Residue is a zombie-related gameplay achievement/trophy featured in Buried for Call of Duty: Black Ops II. This achievement/trophy requires the player to acquire a perk without purchasing it from a Perk-a-Cola machine. In order to acquire a free perk the player needs to kill the last Ghost after navigating the mansion, when the last one has been killed, it will drop a Random Perk Bottle. The achievement/trophy will pop when the player picks up the bottle.
