Over the last week stills and clips of a game called Deadlock, which is claimed to be the next big game from Valve, have been leaking online. The 6v6 hero shooter is either legit or an extremely good fake, and the latter's looking increasingly unlikely with the volume of material that's been released: today, there's more. PC Gamer has contacted Valve for comment but, so far, there's no response.
In the absence of any official word, we can't say whether Deadlock really is Valve's next game...
