console or in the games used. Adobe After Effects is also used, typically by Hullum, to create animated props not found in the regular game engine. Examples of these extra props include tombstones in and ornaments, presents, and lights in the Christmas 2004 video. As the camera player's view has a heads-up display (HUD), black bars are added in post-production to hide the top and bottom portions containing irrelevant in-game information, creating a letterbox effect. Most machinima is made with computer games, which often have HUDs that can be easily disabled in one way or another. Console games such as Halo and Halo 2 are often more limited in this respect. In 2010, Rooster Teeth Productions released a remastered edition of The Blood Gulch Chronicles that removed the black bars and aiming reticle existent in previous versions of the series, which was done by re-shooting the first four seasons in the PC versions of Halo and Halo 2. Other media A book based on the series, titled Red vs. Blue: The Ultimate Fan Guide, was published November 17, 2015. Written by Eddy Rivas and Burnie Burns, it collects information about the series over its first twelve seasons and most of its thirteenth season. Due to the popularity and success of Red vs. Blue, Rooster Teeth has created dozens of Red vs. Blue-themed merchandise available for sale on the website's store. Rooster Teeth has released several posters featuring major characters accompanied by their most popular quotes, dubbed "-isms posters". Several t-shirts based on quotes from the show have also been created. Reception Critical responseRed vs. Blue attracted interest immediately; the first episode was featured on Slashdot, Penny Arcade, and Fark on the same day, and had 20,000 downloads within a day. The following episodes wound up downloaded hundreds of thousands of times, forcing a change on the distribution to peer-to-peer file sharing to cut the increasing server costs. Ramsey noted Red vs. Blue also "had a broader appeal than we anticipated", gathering a female following along with the expected demographic of young adult males. Shortly after episode 2, Bungie contacted Rooster Teeth. Although the crew had feared that any contact would be to force an end to the project, Bungie enjoyed the videos and was supportive; one staff member called the production "kind of brilliant". A deal was arranged to ensure that the series could continue to use Bungie's game properties
