Hostile humanlike raider units will never retreat from the map like Mechanoids (flee message still apeears but has no effect).
When raider decides to kidnap or steal, only units actually holding the downed colonist or item will leave while remaining units continue the assault.
For those who seek unrelenting challenge from one's adversaries.
Mechanism
Unlike other mods that try to prevent game from calling retreat behaviour, Raiders Never Retreat take alternative approach by modifying retreat behaviour directly so that it acts identical to AssaultColony behaviour. This ensures retreating is completely removed for both vanilla and modded factions, except in rare cases where the latter adds their own unique retreat behaviour.
This mod also adds custom ThinkNode_ConditionalDoingKidnapOrSteal code to make only pawns kidnapping/stealing retreats while remaining units do not.
Important Facts
Applies to all factions, including modded ones, as long as they don't add new retreat behaviour.
Can be safety added or removed mid-game as long as there are no NPC units in the map.
Reported to cause raiders that bash walls aggressively when played with Doors Expanded.
