Cool free delay plugin and free horror SFX
I think we can all agree that most of the delay plugins are kinda boring (especially free ones) but seems like this one is different. Coalesce allow you to put different effects before the delay, in the feedback loop and after the delay. You can choose from filters, distortion, ring modulation, pitch shifter, a limiter, and a gain module. There's is also a built-in ducker, diffusion (to turn your delay into a reverb or something in between) and limiter at the end. Oh, and you can do a reverse delay as well, because why not ;). Here's the link:

I also found this mini horror SFX pack (creature sounds, drones, braams and stabs).
