A returning ability from Blood Money and Absolution, any newcomers to the series may be unaware that certain hiding spots you can stash bodies in are usable more than once. The more standard 'chests' that you can dump your dead or unconscious NPCs in can only hold one person each, but anything like a locker or cabinet - something upright - can hold multiple people. Doubling up on hiding locations is the only way to accomplish some of the harder challenges and can aid in the escalation mode too, and although IO Interactive removed the humorous sexual pose bodies would fall into from Absolution, it's still very much worth knowing.
