The Sun Tzu Raider Tactics Mod adds a new and exciting raid type. Pirate raiders will split up to try and flank you. No longer will they be hapless idiots. They have an improved AI and better decision making for a fun challenge.
Additional credits: The modding discord, in particular Why_is_that and erdelf, for helping with code, Xen, for making most of the preview image and XeoNovaDan and VanillaPCStrategy, for testing.
