One of my older maps updated for survival Includes barricade system that needs wood. To get wood destroy the wooden props around the map. To build barricades/repair doors just press E while aiming at the hammers next to them.
Put everything except readme in maps folder. To play start a lobby, then type "mpgamemode survival" without the "" in the console. Then type "map l4dsvcottageofdoomb1" and enjoy.
