I know this may sound silly, but it is a serious suggestion - players should be able to fart.
Before you work your eyes out with the rolling, think of this if you will, there’s an emote of, ‘Insult’, where the player pats their butt with a sense of mockery. Why isn’t there farts?
What if it were a quirk on a weapon where it causes the player’s character to randomly fart which would, perhaps, create a status debuff on wildstock/aliens, which, in turn, will make them aggressive towards you. Of course, only if/when, the said creatures have been affected - as if you tried to initiate the aggression by hitting/shooting/bombing them.
Not saying this should be priority, but it’d be pretty neat to know if there is a staff meeting on the idea of passing gas.
