Tracing the sources of the sounds we discovered that 2 of the sounds came from a proprietary source (which i will not disclose, and i think is best not disclosed here) so cannot be used.
Lol. We basically all know which source it is. :P
By the way, the fuse sound is likely a derivate work of
https://freesound.org/people/Ned%20Bouh ... unds/8320/It sounds very very similar. And it long predates the Source That Should Not Be Named. It's seems the Source That Should Not Be Named has altered the sound a bit.
It's an open secret that the Source That Should Not Be Named has used freesound.org extensively. They often altered the sounds a bit to fit their needs.
So, we could re-do the fuse sound by doing our own derivate work from the CC0 sound above. Then we're safe AND have a good fuse sound. But it's UNSAFE to directly copy the sound from the Source That Should Not Be Named.
I was unable to find the source of the explosion sound on the Internet. Maybe they used another sound library that we don't know. Whatever. But in the Internet you'll probably find a billion explosion sounds.
