Visually, the Torc graphics engine demo, which was set in a first person shooter genre, was nice looking on its own with some nice Doom III like shaders. lighting and effects. But the Havok physics engine was the star of the demo. The demo allowed a user to use Doctor Octopus-like mechanical arms to pick up various objects in the level, from barrels to wood pallets and other objects. Another portion of the demo took place in a zero gravity enviroment where we saw objects float and move around realistically and when then entered normal gravity they fell to the ground realistically as well.
