This game lacks of better sound design. All sounds volumes blend on each other, so you can't hear that you getting hit while tons of nazis shooting at you.
Shooting at nazis doesn't give any impact sounds cause of that blend, so instead I've added hit confirm sounds to fill the lack.

• Hit confirm sound - sugg_card_lock multiplied 3 times.
• Headshot sound - kick_player multiplied 7 times.
• Damage sound - skill_confirm.
