(EXTREMELY MINOR SPOILERS) Question about an early moment in the game (roughly 5 minutes into gameplay)

The devs had mentioned a playtester doing a playthrough "without firing a single shot." Is there a way to get out of that first cave without shooting a shot to blow the barrels up? Entirely possible they really just meant without shooting any enemies but I'd love to have a sneaky way of getting out of there and literally never firing a single shot in a melee build.
