There are two things you need to know about this trailer for an upcoming Left 4 Dead fan film. It is sponsored heavily by Airsoft GI, a seller of airsoft paraphernalia, natch. It's even hosted on that company's YouTube page. You may think the stench of in-your-face advertising would be overwhelming, but thankfully it's not, which brings me to the second thing.
This trailer looks pretty slick. The movie was supposedly filmed over a single weekend, but with the level of polish exhibited, it doesn't feel rushed at all. Well, we'll see about that once the full movie is released. Looks promising so far, unlike that other recent zombie video project that quickly turned to crap.
