Hydrophobia is a survival-adventure video game developed by Dark Energy Digital and published by Microsoft Game Studios for Xbox Live Arcade. The game was released on September 29, 2010 as part of Xbox Live's 'Games Feast' promotion, marking the first of three episodes. PC and PlayStation 3 versions are planned for later release. The game's engine, HydroEngine, provides realistic fluid dynamics technology for flowing water, allowing it to interact with the surroundings. The levels of Hydrophobia were designed using InfiniteWorlds; a game creation system which uses bespoke procedural technology to significantly reduce file sizes, decreasing the overall file size of the game.
