Members - Murderwell mod for Left 4 Dead

This is a custom campaign for Left 4 Dead titled “Murderwell”. It will have 3 chapters and I am considering in making 2 survivor maps with this mod. This is my 1st mod and I am still learning how to use Hammer and how to make Left 4 Dead maps but I am getting better at modelling and understanding more of what is required in a campaign. This is the reason why it has taken me a while to start this mod and I am hoping to complete it as soon as possible. I would be grateful for any feedback and constructive criticism as that’s how I will get better. EDIT: I have considered in extending the campaign to 4 levels with the 4th being the escape level.
