Using sparse backgrounds, 3DS Max and the power of C&C Music Factory, Lionhead animator James Benson has for the last month been taking some of Valve's best characters and breathing a little extra life into them.
In the clip above, Left 4 Dead's Zoey breaks free from the confines of a first-person perspective and figures out a way to bring down a Tank without wasting bullets, while in the clip below, Team Fortress 2's Engineer figures out a way to go left to right (groove) and work you all night, before finally letting the music take control.
Those two are just to get you started; to see the rest (the dance clips are part of a bigger project), head to Benson's YouTube page.
