I'm going to jam on sunday in a band as the sampler and backup vocalist....so yeah, any audio samples would be cool, if you know of any sites with them on.

Anything will do; obscurity wins all.

Just thought I would bump this, I am looking for:

The sound of the egon gun from half life, for up to 10 seconds.
Xen ambient sounds.
The taucannon spin up sound and firing sound.
A good chainsaw sound.
A red alert sound.
An air raid siren sound.

Any ideas?

Lots of air raid sirens here. Best natural/long one is here.
