This came out yesterday.
Mercy - Combat AI Overhaul
List of potential behaviors from the description
-- Hitting an npc might pull nearby friends if they are in a line of sight.
-- NPCs might be unwilling to engage, warn player not to come closer (probability based on disposition towards the player)
-- Can chase, fallback, strafe around in combat. Walk menacingly. Rare actors will jump around or run around the player full-speed.
-- Chain attacks together, max amount of attacks depends on a weapon skill
-- Make mistakes in picking best attack types (more mistakes at lower weapon skill)
-- Some might get angry when spammed with quick attacks and respond with a similar quick spam
-- At low hp (<33%) each damage even has a chance of making them scared, which in turn will result in an attempt to run away searching for a friendly npc, or in asking for mercy, giving up all the items they possess (except their clothing/armor) and leaving the combat state.
-- Probably other smaller things that I forgot about.
This got potential. Thanks for the tip.
Hopefully there will be mwse version too.
