Valve has now filed for a trademark for Deadlock, the hero shooter it refuses to admit exists
Deadlock is a hero shooter that both does and does not exist, which is to say that we've all seen it and talked about it, and plenty of people have played it and are likely playing it at this moment, but Valve has steadfastly refused to acknowledge that anyone is even paying attention to it, much less that it's something currently in development, thus leaving it in a suspended state not unlike, say, a metaphorical cat in a box. But now Deadlock does not exist slightly less than it did not exist yesterday, because Valve has applied for a trademark on the name.
