The Left 4 Dead Authoring Tools, also known as an SDK, is a set of software utilities that allow you to create your own levels, campaigns, common Infected, and other gameplay elements. They include versions of Source SDK tools that have been updated to work with the Left 4 Dead version of the Source Engine.

Warning:For Left 4 Dead 2, please go to the Left 4 Dead 2 Level Creation page. You will however need to master the basics of Source and L4D level design first.
