Since I came back to inf a few weeks ago, I've noticed that the weapons and key assign function has been unlike how I used to remember it being. It is a bit wordy but let me try to explain. Weapons are now being forced into certain keys as opposed to being free form. Before if I want to assign a weapon to the right mouse button for example, and if there is no other weapon (in the primary kit with bold letters) already assigned then there is no problem using my right mouse button (or any other key I want) for it. I can reassign key of those primary kit and then use those keys too. But now some weapons after reassigned keys they will not work. Despite the fact that no other weapons is currently using those keys. I am now forced to (mostly) use default keys per weapon slot as the only way to get my weapons to work. Was this something that was tweaked in the last few years?

Your best bet is to post this on the Infantry Online discord to check with them. They would be able to give the best input regarding anything in game.

Ok, thanks Champ.
