Spiced up kill messages
Because we're not all neck snapping ninjas.

So here's a thought that requires utterly ignoring suspension of disbelief.

Snapping a neck ain't easy. It requires power, and technique. Which, requires training, which most people simply don't have. So, as a bit of added flavor for the individual martial styles (and brawling), I think the actual kill message should be reworked. A lot of individual weapons already have unique kill styles, yet all the unarmed styles are entirely the same.

Here is my proposal:

Rewrite the kill messages (perhaps crowdsourced from fix-it) for each individual unarmed style (Brawling & the martial arts styles) to be more reminiscent of what someone who would fight in those particular styles would more likely use to end a life than a neck snap. A few ideas.

Brawling: replace the neck snap with a head stomp. Literal boot to face kind of energy, maybe make it disfigure the face in the same way other FOIC means do, at the cost of sprays of blood covering clothes and the ground.

Muay Thai: Dropping to the knees and punching a dude in the windpipe until his throat becomes throatn't.

This is not to say a player couldn't spend the time to get the message types from Fix-It and send some new suggestions in to a builder email on their own initiative, but generalized weapon messages have a lot of virtues and I almost always prefer them for being more flexible to lots of different roleplaying contexts instead of forcing an idiosyncratic outcome.

One of the problems with the mad dash crowd sourcing for weapon messages in the day before vehicle combat launched (at least in my opinion) was it became clear that when players think of weapons and attack messaging, they get really stuck on stuff they want to see their character do, in a particular location, one time – and don't necessarily see how that might not translate to other characters in other places, devoid of context that was needed, doing the same thing hundreds of times over years.

When it comes to something like a kill message with martial arts or brawling, you really only can assume one thing: One character kills something without weapons.

You can't know for example what the preamble context of the fight was, whether it was an rare fuelled bloodbath in the street or a clinical corporate takedown where excessive carnage might be utterly nonsensical and require handwaving. You can't know the physical context of the combat, whether there is even a ground for example. You also won't know the characteristics of the two combatants that might make certain outcomes physically impossible or figuratively incoherent: Do those vulnerable spots still exist if they're extensively chromed out, wearing mech suits, battle armour, or have possible but atypical anatomy? Does it make sense for executing character to make certain types of killing blows in all contexts, or are the attacks assuming something about their physical capabilities or styles based on character stereotypes of those weapons?

In a lot of ways the current weapon messaging doesn't always meet these sorts of hypotheticals so it wouldn't be wrong to have more discipline specific messaging, but it's probably going to require a player to write them all up themselves and also demonstrate they would be a clear improvement overall and not excessively specific to one particular conception or context or character style.
