This is a very simple mod to enable you to adjust the range of the Stun Rifle. This is based on the Arc Thrower Range v1.1 by epiceuropean, which is compatible with Long War but, to the best of my knowledge, is not compatible with Long War Rebalance (version 1.25.xx and up). I simply make a small modification to the original mod to make it compatible with LWR.

Purpose of the mod:
To enable user to adjust stun rifle range from the default range of 4. 

Requirements:
XCOM Enemy Unknown with legacy (1.25.xx - 1.28.xx) Long War Rebalance installed.

How to use it:

• Install the mod using PatcherGUI
• After installation, go to your DGC.ini (or XComGameCore.ini), find the Weapons= entry for Stun Rifle and modify the iRange= value. For comparison, pistols have iRange=30 and medikits have iRange=3.
• Play the game! If you increase the value of iRange, your soldier will now be able to shoot the stun rifle at longer ranges. 
  

Caveats:

• This mod is not compatible with older versions of LWR. Use epiceuropean's original mod instead: https://www.nexusmods.com/xcom/mods/630
• Users have reported that this mod is not compatible with series 1.29.xx of LWR (and possibly newer).
• This mod has not been tested with 1.27.xx series of LWR, so I cannot guarantee compatibility with this series. However, users have reported that it works with versions 1.26.xx - 1.28.xx.
• You will most likely need to re-apply the mod when you upgrade LWR to a newer version.
• This mod does not change your soldier's chance to stun an alien. As before, weaken the aliens first before trying to stun them.
  

Credits

• This is a modification of an original mod by epiceuropean. The majority of the code is his, so majority of credit should go to him. Huge thanks to epiceuropean for giving me permission to upload this version.
