Original L4D1 Ambience

Putting the horror back into L4D1 What Valve did when porting L4D1's campaigns into L4D2 is reuse the same ambient effect of the annoying fly sounds for most of the ambient effects in No Mercy. All of the original ambient effects were still in the game from L4D1 so I just reused those. Keep in mind this doesn't just replace the ambient effects for No Mercy, it does it for all L4D1 Campaigns. Sorry for the scuffed screenshot and demo video, I'll be working on making better versions of them soon like a custom icon for the workshop and better quality demonstration video. I do go to school in person so I haven't had much time for modding and stuff. THIS REPLACES ONLY L4D1 CAMPAIGNS ONLY! L4D2's ambience have a certain style to them that fits the campaigns, so I decided that I wouldn't touch them, If people do want the ambience effects to replace all campaigns I will do it but it won't be any time soon.
