I've recently been reading through the long-running comic series B.P.R.D. - I've been taking each volume out from Canada Water Library's extremely well-stocked comics section - but you can currently buy the entire series in PDF form from Humble Bundle. I'm halfway through the series at the moment, and based on what I've read I'd recommend it highly!
(I would note that the first two volume are not good - you should just skip to the start of 'Plague of Frogs')
B.P.R.D. follows a government agency which is dedicated to protecting America from supernatural threats. The series follows a group of people who are not really up to the task that they've been landed with. The series is truly apocalyptic, depicting a gradual falling apart of the protagonists as well as the fabric of the reality that they're trying to protect. In general things just get worse, trust gets eroded, and the world is slowly then rapidly destroyed.
