Little Devil Inside

Little Devil Inside is a third-person 3D action-adventure role-playing video game with elements of survival, combat, and open-world exploration; however, its developers, Neostream Interactive, have described the game's survival elements as "rather easy" compared to other games in the survival genre, stating that the game is "not about how long you can survive in a certain environment", instead being about "taking a trip for a mission, and surviving during the process." Examples of in-game survival elements include harvesting water from cacti, chopping wood to make a fire, and cooking food obtained from hunting. Players can use a variety of weapons and tools to survive and accomplish their objectives, such as a sword, shield, gun, grappling hook, bombs, tent, and cooking equipment.

The game takes places across multiple locations with differing environmental conditions, including desert, snow, forest, mountains, swampland, and deep-sea diving. These areas are connected by a "world map", which uses tilt-shift effects to create the appearance of miniature scale. Although this overall map is available, players cannot "fast forward" their travel to these locations; instead, they must take direct control of their transportation during the journey and respond to events that occur on the way, such as encounters with NPCs, overcoming obstacles (such as a flock of sheep), or being ambushed by enemies. Players also have the ability to upgrade their transportation (alongside their weapons and armor) as the game progresses.

Little Devil Inside takes place in a 19th-century, Victorian-inspired setting, with elements of steampunk. The developers describe it as a "surreal, unrealistic world ... somewhere between heaven and hell." The main character, Billy, is a swordsman, employed by a research team (led by college professor Vincent and his colleague, Dr.

Oliver) to travel the world in search of the supernatural and other unusual incidents. The ultimate objective set out by the researchers is to assemble a complete encyclopaedia of "all phenomenal existence."

Little Devil Inside was originally conceived by its creative director, Kody Lee, and was developed as the first game by Seoul's Neostream Interactive, who initially began in 1998 as a multimedia design & production company. Development began originally using the Unity Engine, then later switched to the Unreal Engine by Epic Games. The game was first announced through a Kickstarter campaign in April 2015, alongside a pre-alpha trailer and gameplay footage, and an entry on Steam Greenlight. At the time of the original campaign, the game had an approximate release window of "Fall 2016."

Backed by over 5,000 people, the Kickstarter campaign raised A$306,515 by its completion in May 2015. Subsequently, the game's original release window was pushed back, due to an increase in its scope.
