Hi there! I enjoyed this class a lot in base Xcom, so I modified it to work correctly with Long War 2! I changed the broken stock pistol to a sawn off shotgun for defense, and gave it a few stealth and positioning oriented perks for the middle tree. Hope this helps those of you that want to keep using this class!

If you paste the below code in the file XComClassData.ini in steamapps\workshop\content\268500\658531225\Config, it'll update the class to my LW2 version.
