No feedback when no grenade

Hi!

When trying to equip/use grenades, there should be some type of feedback indicating the player has no more of them (when it’s the case). Either a voice line every X attempt/second, and/or a little “error” sound or something of the likes.

When trying to equip them, I thought my keystrokes were ignored because of animation, being hit or whatever, audio feedback would help a lot in that case.
