since this "mod" uses some sound files that are larger than original sound files, your going to need to run

snd_rebuildaudiocache

exit

reopen the game, and run snd_updateaudiocache 


if you dont the game will cut sounds off awkwardly.

(version 1.3)

replaced HIT sounds (music that plays when your teammate(s) get hit by a special infected
defib now players the lbp respawn sound slightly later
added new pickup sounds
likely more i cant remember
