L is for Limping
Injuries are going to happen when the world ends, this is a fact. And not just the random characters you kill off in the first chapter, but your main characters and secondary characters, whether you intend to keep them alive or not are just as susceptible to harm as anyone else.
You’ll need to make injuries realistic – you’re not going to get far in the nuclear wasteland with your leg chewed off by mutated wolves, and think well in advance how those injuries will affect your characters long term. That guy who lost his hand in a mincer? How is he going to fire a weapon, dig a hole, drive a vehicle?
To gore or not to gore, that is the question. Again, you need to be realistic, but you also have to think of your target audience – those hard-core horror fans and survivalists aren’t going to feel faint at the description of some blood and guts, but your human-interest-story fans may not find pages describing that decapitation necessary to the story. Strike the right balance and you’ll keep everyone happy.
Ironically, I'm posting on Friday 13th about injuries - have a safe day!
