Way of the Samurai 4 (WotS4) is an action-RPG developed by Acquire (2011). The game has a dedicated modding community that adds new weapons, outfits, items, mechanics, balance changes, QoL (quality-of-life) improvements, translations, and bug fixes. Because WotS4 was released on PS3 and PC, most PC-focused mods are distributed as file replacements, patches, or external trainers. Below is a structured, actionable guide covering types of mods, where to find them, how to install and manage them, common tools, compatibility notes, and recommended mods and modding projects.
