I'm sorry, but there is no controller support for re[Mod].
And a note on the shotgun barrel spread: the other mods on your weapon can modify weapon attributes like spread. If you have a scope/grip attached, that causes spread to decrease.
Thank you for the kind words! If you'd like to check out the map, but don't have 6 people to start the match, you can open the console with "~" and enter the command "force-start 1" This will start the lobby countdown. Thanks again!
