Depth is a new multiplayer stealth/action game using the UDK to set a team of divers versus sharks. The Depth Website is online, offering a GDC Gameplay Trailer showing the depths to which the game is willing to sink. Here's an overview of the game: "Off the coast of present day Mexico a team of fearless divers are preparing to loot sunken treasure from shark infested waters. To emerge with their limbs intact, they must use every trick at their disposal to outsmart, avoid, or disable a pack of vicious man-eating sharks. Depth is a competitive multiplayer game which blends heart pounding hide-and-seek gameplay and visceral action in a dark aquatic world. Predator, or Thief, which will you be?" Thanks Joao.
