Doesn't seem like anything more than a demo. Short and unattractive.
The repetitive play and single map implies that the original author never intended this to be a legitimate campaign. My guess is that the author was merely exploring how he could bend the Counter-Strike:Source code to work with Left 4 Dead. Play it if you choose, but don't expect much.
