Howling wolves, perfect for a gothic graveyard.

This set is a LOT of various screams from someone out of sight. Never hear the same scream twice, probably; unless the randomization's unlucky.

This is a set of explosion sounds for deadly environments! There's a falling bomb for the distance, a close by explosion, an artillery unit firing, a falling artillery shell, and an explosion causing a building collapse. A good variety of similar things!

This is a set of creepy demonic drones and other evil sounding stuff to give a mystical, malevolent vibe to a location.
