Deadfall Adventures has been developed using Unreal Engine 3. It is reportedly inspired by action adventure books and movies such as Indiana Jones and adventurer Allan Quartermain (from the novels written by Henry Rider Haggard). The development team researched popular films and also took assistance from movie industry professionals to capture the treasure hunting genre’s tone and look. Nordic Games’ Reinhard Pollice stated that there will be advanced graphics and control options for PC players which will allow them to play on multiple system configurations. However, he also stated that they don’t want to make any version of the game better or different. The game was earlier announced to be released on July 30, 2013 but was then delayed to September 27 and then to November 15, 2013 when it was finally released. A collector's edition was also released which contains an Allan Quartermain revolver skin for the revolver in single-player mode and three multiplayer skins, a "Making Of" DVD, original soundtrack CD, a printed game manual and a "Bonus Content" DVD which includes an artbook. A beta version for Linux was released on December 31, 2013 for those who bought the Windows version of the game on Steam. On June 11, 2014 the developers announced that a PlayStation 3 version titled Deadfall Adventures: Heart of Atlantis will be released in the summer of 2014 with a number of enhancements. The game will include a new co-op survival mode, new boss fights, cutscenes, locations and an improved leveling system. The graphics have also been overhauled, according to the developer.
