Jaws:Unleashed uses the Ecco engine, the 3D one of course, not that antiquated typical Megadrive 2D engine
. The new Jaws game freakin rocks, highly recommended.
As for the graphics, well I don't think there's anything there that DBPro couldn't handle, a nice specular shader for the dolphin skin, a decent water shader, and the remainder of the work is mostly modelling and texturing
. There's a destinct lack of underwater games in DB/P, except recently we've got SubSurface of course, but I think DBPro could make a gorgeous underwater game if it wanted.
