So, I'm making this creature. While making it I'm wondering, some things about how humans will react to it and likewise.
In 2037, World War 3 breaks out. Instead of nukes, the countries warring with mutates and viruses. One side (lets call them AU) of the war launches a virus that change the DNA in infected humans in 10 days after entering the host., making them mutates. AU's virus will stays active for 5 years before the virus dies. Anywhom, the virus backfires and it spreads all over the globe. Since of AU's stupidity in not making a cure for pre-mutate infected, the whole world got overrunned in a matter of weeks. 100 years after, there are 2 human-like lifeforms in the world. Humans and Muts (mutants from the virus)
Humans: After 100 years, humans' complete tech level is a bit above shotguns, rifles and swords/bows (they know farming and stuff). Other than small parts across the globe of labs and alikes, anything that the humans didn't forget about life before the war and the war itself is drowned in godly powers and alike.
Muts: 1. Since because of the war needs, muts live short lives, and able to gain thousands of new warriors since child muts mature after 1 year. But muts rarely grow past the age of 6, let alone 10.
Due to evolving, muts became humanly smart over the 100 years. since muts became a lot smarter, there are factions within Muts, and some want peace with humans.
Muts are gray-skinned creatures with sharp fangs/claws for shredding. But there skin is more or less easily ripped apart. With smaller body size (~2ft) they can hide easier. There can be ~10,000 in hordes.
Muts have outstanding memories (aka they filter out unimportant things and can have some memories of there mother) so ideas must quickly kill fast and can't happen again for ~12 years. 3 Here's the thing, without a lot of food, they become dumb and disorganized (after 2 months they start to become dumb in order to not starve. They can be starved for 3 months more.)
Lets say that humans/muts are involved in a major war. Each side wants to destroy the other. Since the story takes place in a human side, what weakness could the humans exploit, (aka use in order to kill most of the muts) since I have no clue how people might go in order of this, (not a general) I would love some help.
