Introduction

The official UWE Extension is a Mod for Natural Selection 2. It was automatically loaded on any Dedicated Server and it was mandatory to run on all Ranked Servers. It was a way to add minor balance changes into the game without releasing a new Patch. With the introduction of UGC support with (Build 340) it was replaced by Matched Play Balance Mod. Every Player automatically subscribes to Matched Play Balance Mod in the Steam Workshop. The current Changes can be found by clicking the Balance Gorge Button (10) in the Main Menu. Not every iteration of the Mod is released to the public, which is why version numbers in the changelog are missing.
