Every day here at Doom HQ we receive tons of tips from our readers about really cool stuff from the world of geek, as well as promotional materials for new films, comic books, collectibles, and much more. While we do our best to bring you as much of it as possible, we don’t always have enough geek manpower available to cover it all on a daily basis. But we hate the idea of all of this really cool stuff wasting away in our inbox. How could we NOT cover it? Hence why we’ve resurrected our long-defunct column Bits Of Doom, now rebranded and revamped as Doom Digest, a collection of easily digestible bits of news, videos, photos, and other goodies.

Today: Limited edition 35th anniversary commemorative t-shirt for Disneyland’s Space Mountain attraction, the DVD/Blu-ray trailer for Season 2 of AMC’s The Walking Dead, a Game Of Thrones featurette, infographic & digital sampler for Dark Horse‘s vampire comics, President Obama on The Avengers movie, and Slinky on a treadmill, plus Bits Of Doom.
