Concerns not being able to equip heavy weapons like the shredder gun on a modded class like the rogue or any other, I know the fix for the heavy weapon, the thing is heavy weapons themselves classify as a code like this: +AllowedWeapons=(SlotType=eInvSlot_HeavyWeapon, WeaponType="heavy") So in theory, adding this to the XComClassData.ini of the modded class should fix it.

P.S. does anyone know that if you switch the pistol as a secondary weapon with a sword, would that crash the game or would it look like a cosmetic since there is no sword skills.
