About this mod Author’s original text

ImprovedSurvivorAI

For the most part, AI-controlled Survivors are plagued by egregiously low activation ranges, weird skill prioritization and an aversion towards sprinting when it would be appropriate to do so.

This mod rewrites the behavior tree of every single vanilla Survivor in the hopes of rendering them far more competent brawlers. It also grants them full awareness of their enemies' positions, ignoring both angle & line of sight requirements, although they will prioritize targets within line of sight if possible.

Also comes pre-packaged with improvements to the Engineer's mobile turrets; they now always sprint when following you, and their maximum attack range has been improved from 25m to 35m. These changes can be turned off.

This mod indirectly but very noticeably buffs Goobo Jr., so be on the lookout for that:P

Oh, and watch out for the Artifact of Vengeance.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
