Hellchick's announcer sounds, and
CPMA sounds: armor sound, platform moving sounds. For CTF, OpenArena has more announcer sounds than the original Quake3, so with this pack it will be a mix, for example:
Mancubus (default OA announcer) saying "red flag returned" and then
Hellchick saying "blue leads".
;)
Sounds played when Sarge takes a hit. (Due to an OA bug, it's better not to be used on Elimination servers.)
Replacement for broken sounds: sound/world/curnt2.wav. This sounds like a water stream larger than the Q3 version, or at least has more echo, but it's fine.
