Space Kill, no protagonist, slice of life (might have a bit of a main plot)
A daily tug-of-war between impostors and crewmates plays out aboard a space station in the depths of space. Today, parts vanish from the engine room. Tomorrow, the oxygen supply mysteriously dwindles. The day after, someone gets "tossed" out of the airlock, then secretly climbs back in. There is no protagonist and no villain, just a bunch of cheerful people (Note: I don't know what personalities the Space Kill characters have, so I'm making it all up) turning a tense, thrilling game of space murder into a lively communal life. After all, in this boundless universe, having someone to mess around with is the best thing of all.
