Useful. Thank you for the sharing. They remind me some sounds from the 80' games :)

Here is my little collection of retro-like sound effects, perfect for some sort of shooter. All the SFX files are nicely named and are in a WAV format. I've also prepared a preview video for you, shown in a sidebar (or above, if you're browsing with a smartphone).
I distribute the sounds under the CC0 license — meaning that you can use these SFX however you want. Crediting is not required, though always welcome.
