I have a little bit of a dumb theory. When we level up a revolver to level 4, we will have 4 rounds available to us. You'd think that'd be weird, wouldn't you? But in Chinese, Korean and Japanese mythology, 4 symbolises death and failure, so it's worth thinking about.
Although there is a Laika revolver in the FvsF game! But already with 6 rounds, although the developers could have made it with 4 rounds, which hints at some thoughts. It would be funny and cool if it had 4 rounds (like 4 rounds but more damage).
What do you think?
