If you're a bit of a sci-fi fanatic then this collection of sound effects will be perfect for your phone.
Sci-Fi Sound FX is a collection of 30 different futuristic noises in MP3 format. All are contained within one Zip file and once opened, a collection of Space-age treats are waiting for you. Examples include roaring rockets, bleeping buttons and electrifying lasers, and most of them are the perfect length for an incoming SMS alert.
I was disappointed at the lack of alien noises, but Sci-Fi Sound FX is still an interesting selection of alerts.
