It just goes to show what two geeks with $500 (Canadian), a PC rendering farm and an obsession with Half-Life 2 can achieve. This is the first part of an apparently intermittent live-action film series set in the Half-Life universe, made with the blessing of original game developers Valve.
Seriously, this is impressive stuff. The opening shot of City 17 is amazing. The acting is a little cheesy, but as one critic put it, this is already the best game-to-movie translation ever made. The first episode has already been a massive success on YouTube, with 1.5 million viewings in less than a week and it is already the most highly-rated video in the website's history.
