MadFox informed me that the progs.dat wasn't included for the voidents mod (making it very hard to use, stupid me), so I've uploaded a progs version that's immediately playable. If you want to put stuff like radars, laser gates, pits, flame spouts, any kind of eye candies, triggerable sounds, etc into your maps you may be interested.
The included start map does a good job of showing them off, as does mines.bsp that can be downloaded separately. If you have any question what these entities do, those maps will answer most of them.
