Vipersound for Flightcore

Add viper`s sound when active flight core

Different with OS replacement,I made this because Titan OS is very easy to be interrupt by other dialogue or just didnt play at all.

So I replaced flight core`s sound effect to make sure it will play every time you active flight core

v2.0.0：Now it will as same as viper`s flight core!

Thanks for Xiaobbuguai.He inspired me to solve this problem!

Enjoy your Northstar with Viper`s Flight core Scream!
