Have you ever noticed that sometimes Zoey, Louis and Francis does not play fall scream lines while falling off the ledge or also jump off from the high ground? It appears that it shows an error on the console "player/survivor/voice/(survivor/fall04.wav is missing". It also adds Ellis's extra fall scream line while falling. Ellis has 5 fall screams lines and the game only plays 4 lines.
This plugin will fix their missing lines while it plays one of the fall scream lines.
It should save l4d2_fall_scream_fix.cfg in your \cfg\sourcemod\ folder.
l4d2_ellis_extra_scream: 1 "Enables Ellis extra scream while falling"
