Place this clip at the start of the clutch sequence, right after the Bomb Has Been Planted Sound Button sets the round. Follow it with the Enemy Spotted Sound Button on first contact, then cut straight to gameplay without another effect in between.

This is an 11-second voice clip of a player reacting in panic during a 1v5, repeating that he is so scared while outnumbered alone. It feels tense and funny at once, capturing that shaky, overwhelmed dread of knowing the whole enemy team is still up and the round rests entirely on you.
