Its a game made with UDK and using all the assets which epic supply.
Keeping things sort...You play an agent sent to investigate this location and discover what happened to those who disappeared previously. The player will begin from deep underneath in the caves and make your way up into the mansions secrets.
The game is a horror game but with a different pace to it. I want it to build tension as the player progresses. The game will feature puzzles and investigation.
