Before you start
- Install Metamod:Source and SourceMod first. See install SourceMod on Left 4 Dead 2.
- Use SourceMod 1.11 or newer. The plugin refuses to compile for older versions, and DHooks is built into these versions, so you don’t install DHooks separately.

Left4DHooks merges the older Left 4 Downtown and L4D Direct projects into one plugin. It gives other plugins access to game functions such as Tank and Witch spawns, director events and survivor states. Plugins that need it list it as a requirement on their download page.How to install Left4DHooks
