While game studio Valve torture the world with a lack of updates to the Half-Life universe, animator James Benson has whipped up for kicks his own vision for an updated, improved Half-Life game.

Benson, who put together the brilliant Dance Fortress 2, has modelled not only a more fluid set of movements for Half-Life hero Gordon Freeman, but for the first time we get to see his legs, too!

Note this isn't an official concept piece or anything; Benson is simply an animator who likes to keep a very public sketchbook, so if you've begun penning angry letters to Valve, you can stop and take a deep breath.

The whole thing is very intimate, immediate and cinematic, taking as many cues from Call of Duty as it does Half-Life. We are very impressed.
