Key17 Games was founded 2010 by Christian Werner, the lead designer and programmer, and Sebastian Braun, who is responsible for the unique graphic style. Both have been gamers for a long time, playing through each and every genre. While Christian is working full time on the games meanwhile, Sebastian is employed as a programmer elsewhere, spending most of his free time to create those gorgeous graphics. Undead Legions is their second game now after Battlepaths, which was released in late summer 2012 for XBLIG and Windows PC.
