"A tipster's put us on to this casting call, supposedly available on subscribers-only industry site Breakdown Express (he's a subscriber, you see). It lists a voice-acting job, working for Valve. Working for Valve doing Portal 2 work. Said work begins next month, and in briefing potential actors for the role, a ton of details on what must be one of the game's major characters is revealed. If you don't like having this kind of thing SPOILED, move along. Move along. If you wouldn't mind taking a peek inside the sequel's world, though, click through for the character description, along with some concept art of the guy in question, just in case you're a budding voice actor and would like to get your tone just right."
