Project 'Reloading' (before Polycount Update, but renewed now).

It's not about existing reloading. It's more about default button R(most used for reloading) and about 2nd Alt.Fire (1st one is bound to RMB, known as M2).

As I often do, let's start with classification:

Chapter I: Classification of the weapons.

I'm going to use the symbol "^" to mark weapons that already have function of the alternative fire and the symbol "^*" if you can use ALT.FIRE-button when this weapon is equipped. Also, I will include weapons that have option to be reloaded to this classification with remark "R". (?X?)-mark is for items that can't be switched to.

 Let's continue with ideas of possible alternative fire for these items:

Chapter II. Ideas and analyzing. (Press R.)

First idea was: while Taunting, if you press R - your Taunt stops. I just wanted to write it here, nowadays I don't like this one. So, it's 0th idea.

1st idea. Melee weapon: throwable by pressing R. Non-melee: use like a melee by pressing R.

Other ideas, step by step:
