Tired of scrolling the mouse wheel to select weapons? It's time to install a script that will give you the ability to switch weapons to buttons. Namely, the numbers ( and - = ).
The script has one feature. If the weapon slot is blocked (for example, some mission forbids changing weapons), the script will ignore this and switch weapons anyway. Whether this is an advantage or a disadvantage is up to you.
The script was created and tested with game version 1.1
