The macro "RB" for "Point Blank" can be downloaded and used on regular mouse and keyboard. Installing the macro is in the Keyran program and increases your skill level in the game, if you follow the instructions!
This macro for the R.B. 454 SS8M pistol automates the firing and switching of weapons by pressing a certain button. I recommend tying it to the side mouse buttons. Get ready for a more convenient game! Good luck!
