A few people might have caught sight of the above video on YouTube, it being the first part of an HL2-inspired fan series directed by the Purchase Brothers, which sees a number of resisting citizens escaping from City 17 around the time period of Episode One. Valve, the developers of the Half-Life franchise, have expressed just how impressed they are with the fan project, which was put together using chroma keying effects, some fantastic acting and a extensive use of the Source SDK for some in-game environments.

The second part of this series is expected to be released very soon. Keep an eye out on the Purchase Brothers website and their YouTube channel for updates!
