This is what i consider the best Insurgency Mods to have installed. they really improve the game and is what i currently use.

________________________________________________________________________________________________________

Here's what i consider 2 must-have keybindings:
- the Sound Restart Key (to restart the sound with just one press if it glitches or doesn't work properly)
- the Resupply Key (to resupply with just one button and saves you the trouble of resupply by going through the menu,must-have when in a hurry!)

To bind these 2 keys,you need to do the following...

Copy the text on the line below:

bind "P" "snd_restart"

(You can replace "P" with any key you want.)

Start Insurgency and open the console prompt. (usually to open it,press the button in between Tab and Esc)

Press "CTRL+V" to paste the text into the console.

Press "ENTER"

Press the "P" key

From now on, each time you start the game, you will only need to press "P" to get all the custom sounds working. No more typing in the console.

Note: you can replace "P" with any key you like. I just made it something obvious and out of the way.

For the Resupply key it's the same process

bind "H" "inventory_resupply"

(You can replace "H" with any key you want.)

Important Note:
This changes will only last until you shutdown Insurgency. If you want to permanently add the key bindings create a file in C:\Program Files (x86)\Steam\SteamApps\common\insurgency2\insurgency\cfg called autoexec.cfg. Open the file with notepad and add the 2 keybinds i told earlier and then hit save.

Hope this helps.
