Demon Core is a first-person survival action game, featuring an edgy female protagonist; a scientist forced to take up arms when everything falls apart. Aspects of the game are unique artistic style combining near-future high technology with exotic Russian design and innovative gameplay elements allowing you to: Hide in the shadows and blend in with victims, even pretend to surrender. Take an edge in combat and defeat the enemy by using your wits. Use your own and stolen weapons to set up traps and triggers. Take control of the trap, create your strategy and take out the remaining few enemies while they are disorganised. Perceive the enemy chain of command and see the team dynamics that you can affect by targeting the right man at the right time. Identify distinctive personality of each enemy, defining his behavior in combat. Immerse yourself in the game using Microsoft Kinect or NaturalPoint TrackIR to detect your head movement and reproduce it in-game.
