As if you needed more this evening, Valve have put the Meet The Engineer video on Steam.
Very different from the previous two trailers, but still just as superb, the Engineer takes things at a remarkably casual pace, strumming away on his guitar, gently explaining his nature to you, while his hand-made machinery slaughters any who might come near.
His profile will be with you after this short break.
Weapons: Shotgun / Pistol/ Wrench
Contraptions: Turret / Dispenser / Teleporter
This amiable, soft-spoken good ol’ boy from tiny Bee Cave, Texas loves barbeque, guns, and higher education. Natural curiosity, ten years as a roughneck in the west Texas oilfields, and eleven hard science PhDs have trained him to design, build and repair a variety of deadly contraptions.
It's smart, and once again, the facial expressions are of a quality beyond reason. Six days until the beta, six days until the beta, six days until the beta...
EDIT: the thing in full.
