Hi guys, I’m making a FPS game.
I’m doing it alone, then share with my friends.
So, anyone know a website where I can do better domwload or even buy sound effects for weapons or my fps game, eg: A Shotgun, AK-47, pistol, grenades and so on …
If anyone knows, please send me the link.
Thank you 
The answer is: anywhere you can find them. There are a ton of sites on the internet with sound effects and assets that you can get.
Here are some: Yahoo | Mail, Weather, Search, Politics, News, Finance, Sports & Videos
Here are some more: Free Sound Effects for All Occasions: 40+ Download Sites - Hongkiat
It look like a very old post, but what we’re doing now is to solve this problem.
We created a professional FPS gun sound solution.
