New artillery incoming noise. Now they sound more aggressive, and no longer share the same wistle sounds with the bombs dropping from bombers.

Previous small updates include new explosions for Mk2, Millsbomb, and No.69 explosion sounds. They now have more of their own characteristics if you listen closely.

For example No.69 explosion now sounds faster, and sharper, with less resonance compared to other more powerful nades.

Mk2 and Millsbomb have very small difference, but they now sound very different from the German Stielhandgranate.

New bullet impact sound on the following materials:
concrete
flesh
glass
metal
wood
ground surfaces

Repaired the emitter "counter_attack_siren", (which I created ages ago) it was cut off early. This emitter is triggered randomly in coop when enemy respawns and launches counter attack. The vanilla version was a simple air raid siren, not so exciting.

In my version, you will hear a small plane flying by in the distance (imagined friendly recon plane), then you hear some bursts of anti-air guns, the recon plane gets hit, descends and crashes. You can try these in the links below:
