This is a collection of sound effects that I've come across recently. All sounds are from various locations, and sources. Feel free to check them out. I picked them out with game creation in mind..
Some of the contents include rooster crows, Button sounds, UFO sounds, Coins, Swords, Splats, Clicks, and a few musical pieces.
I just sweetened the pot by adding an Interface collection. There's sounds in there perfect for menu select, and error selections, also some are perfect for potion used SFX and the such.
