Hi there,
I just released Essential Outdoor Ambience Sound Pack on Unity store. This is a perfect starter pack to spice up your game’s environmental audio. The pack contains over 60 ambient sound effects ranging from city traffic, trains and construction zones to mountain waterfalls and forest streams.
Also check out a FREE (for a limited time) addition to the original pack - Essential Outdoor Ambience - Loops. Over 30 ambient loops absolutely free.
Any questions or feedback is appreciated.
