For this tutorial we will be making a simple 2 level campaign that never ends. Sounds fun, right? Well, maybe not, but the purpose really isn't to have a full campaign, but to explain the basics of level construction in L4D.

First, lets cover what our L4D campaign will need to work right:

• A director
• A starting point
• 2 safe house doors
• Some weapons, ammo, and health
• A rescue closet
• A change-level
• A fog controller

Here's the map's layout and set up.

After running nav_generate we no longer have the nav error message on the screen when the map loads. Lets take a look at what nav_generate did:

select_with_attribute DOOR

select_with_attribute CHECKPOINT

select_with_attribute RESCUE_CLOSET

select_with_attribute ESCAPE_ROUTE
