Blade Interactive was founded in 1998 by a group of industry veterans, eventually to become a specialist developer of pool and snooker games. They spent three years developing the upcoming HydroEngine. As part of a major expansion, Blade Interactive has established a new force in mobile game development; The new division based at Blade Interactive's new office complex in Manchester is to be known as 'BIG' (Blade Interactive Games).

The HydroEngine is a video game engine created by Blade Interactive over a period of 3 years for next-generation consoles. It has a unique capability which allows modelling of flowing water and other liquids for the first time. It is entirely dynamic, which means the effect is not repeated and thus allowing different effects each time. The engine can also interface with solid body physics engines such as Havok, which allows objects and debris to be carried with the flow.
