Wonderful to hear of the new planned feature, and thank you for the reply!
I also noticed that there are keybinds for alternative fire (mode?), but I don't recall this working during my last play through and won't be able to test for some hours. Am I correct in assuming this refers to a different method of firing the weapon rather than having a backup keybind for normal shooting? If so, is that implemented yet?
All the best :)
