Here is the example of the siren sound on the sound board 4m
I know there is the siren, but I can also program other sound effects if needed.
I already made a sound module for the proton pack
Here is one from a gbfans member
And here is one from another gbfans member
Let me know if anyone wants a Ectomobile siren or anything else. I can set it up so you flip a switch and the siren starts with the wind up sound, then plays the siren in a continuous loop, then when you flip the switch off the siren winds down and stops.
You can hook it up to a loud speaker and it will be so loud you will be able to hear it coming down the road.
