I've tinkered a little bit with the new functionality. Looks good so far. One thing I'd like to be able to do is have the dynamic sounds avoid playing the same sound twice in a row.

Other than that, a few comments on various achievements:

Does NICE THINGS have a planned trigger condition that will be implemented in the future?

Why is there no kill streak achievement for 15 kills? It seems strange to go 5-10-20-25-30...

It looks like PISTOL WHIPPED, RUN AND HANGUN, and SIDEARM SLAYER are 4/8/12 kills with sidearms, is that correct?

Any chance on adding custom achievements to voice packs in the future? For example, I have a voice line that says "That grav tank just tried to run you down!" - could I make it play after being crushed by a magrider?
