The Kickstarter home of Shadowrun Returns has details from Harebrained Schemes on the Dragonfall expansion for Shadowrun Returns, saying this will be followed today by an official announcement (thanks nin). They announce the expansion, known under the codename "Berlin," will be released in January 2014 and will be accompanied by a new Campaign Pack edition of Shadowrun Returns that bundles the game and the add-on. Here's a feature list:

• Experience a New Full-Length Campaign: Return to the “Tech meets Magic” future of Shadowrun as you and your team of runners get drawn into a treacherous conspiracy. Operating out of an offbeat central hub neighborhood, you’ll choose which missions to accept and how you’ll approach them while navigating the dark underbelly of “the Flux”.
• An Exciting New Locale: Shadowrun: Dragonfall transports runners to the Free City of Berlin, a thrilling Shadowrun setting full of gorgeous new hi-res environments, a diverse new cast of characters, and a new soundtrack by the composer of the original Sega Genesis Shadowrun game, Sam Powell.
• Command Your Team: Lead a small team of shadowrunners, each with their own outlook and backstory. Each member of your team is designed to play an interesting role during missions and has a unique set of skills, abilities, strengths, and weaknesses.
• New Weapons, Cyberware, Enemies & More: Try your hand at the long-range sniper rifle, devastating grenade launcher, or stun-inducing taser. Chrome yourself out in the latest cyberware and take on deadly new enemies - including new magical creatures like gargoyles and fire drakes. Dragonfall brings a host of new items, characters, portraits, and improvements to the Shadowrun Returns experience.
• Save Anywhere: You can save your progress at any time during the game. This functionality will also be added to the original Shadowrun Returns “Dead Man’s Switch” campaign.
• New Game Editor Features: A wide range of enhancements to the game editor for community content creators - including a scripting system to better control lighting, tracking mission objectives in the main game UI, placing exploding barrels, and allowing players to input keypad passwords and custom text strings in conversations. In addition, content creators will be able to use all of the new Berlin environment art, items and characters in their own stories along with assets from the original Shadowrun Returns campaign.
