It started off as just another tourist diving trip for Jack Hard, but instead he gets caught up in a global conspiracy. The infamous terrorist organization United Arms has discovered a new source of energy on the ocean floor. It is sure to change the world forever - but to what end? The terrorists are planning to use it in the construction of a weapon of mass destruction!

Fight your way through breathtaking firefights, claustrophobic hallways, gigantic train depots and secret laboratories and avert the global cataclysm. Don't forget: Millions of gallons of water weigh on your head down the ocean floor and every breath you take could be your last.

The demo includes the third mission which takes the player into the terrorist-occupied interior of the underwater station - and into the workings of a giant centrifuge.
