Ready at Dawn has released a new developer diary that delves into The Order 1886's arsenal of weapons.

As Ready at Dawn revealed at Gamescom, inventor Nikola Tesla will appear in the game to supply your team with weapons, which are in part based on real, Victorian-Era technology, and part science-fiction.

"Because our Industrial Revolution is a result of the war between Humans and Half-Breeds, many of the inventions of our timeline are primarily focused on ways to aid in this fight," Ready at Dawn CEO and creative director Ru Weerasuriya said in a post to the PlayStation Blog. "Guns such as the Carbine, the Coach Gun or the Maschinenpistole are common occurrence in the game and represent the technology of the era. While others based on electricity such as the Arc Gun, or based on alternate ammunition such as the Aluminum Iron Oxide of the Thermite Rifle, provide a way for us to use real technologies and materials of the times, while building weapons that did not exist."

Lead Concept Artist Joe Studzinski said that to design the order's most basic weapon, the combo rifle, the team looked at all the issued rifles from the beginning of the Industrial Revolution to World War II in an attempt to create the Victorian version of the AK-47, with an alternate fire mode that delivers a concussive blast.
