I'm a professional writer who's been playing TF2 for years - mostly on Xbox 360, sob - and was recently inspired by Gabe's interviews on The Nerdist to pull this together. It's a short film script introducing 2 new characters and trying to encapsulate some of Valve's overall approach to the world. I'd love your feedback and advice (is it clear what's going on? Is it funny enough? What could you change?): you can read the first draft here
in pdf form. My apologies if this is the wrong place to put this, I'll also post it in the Source Filmmaker forum.
(edit: it seems box.net is displaying the pdf in italics to some people. This is annoying. The downloaded pdf seems fine.)
