Upgradable Bandits and Looters (Without Disciplinary Perk) is a mod for the game. It allows you to upgrade your bandits and looters without the “discipline” perk, which is currently broken in the game. This is the only mod that removes the perk check, so you will be able to upgrade your bandits from the start of the game.

This mod is a simple one, and you can install it without any problems. All you need to do is to download it, open the file with a text editor, and make a few changes. It is very easy to do, and it will save you a lot of time and effort.
