Just about everything in the environment is interactive, and obeys realistic rules of physics and structural deformation, thanks to Havok physics, euphoria biomechanical AI and a process called Digital Molecular Matter. DMM enables the realistic, real-time destruction of objects based on what they're made of; wood cracks and splinters, glass shatters, metal bends and deforms. All of these processes are rendered in real-time, meaning no two objects ever break the same way and giving the player’s actions a visceral sense of power. Combined with Vader’s chilling directive to “leave no witnesses,” the player is given free rein to smash everyone and everything in sight. Take a look at this video to see Haden Blackman and other devs talk about the integration of Havok, euphoria and DMM in The Force Unleashed.
As The Secret Apprentice cuts a swath through the facility, enemies react in realistic ways, as dictated by the euphoria engine. Some of the most interesting attempts at self-preservation we saw were when stormtroopers were caught in the merciless Force Grip. Knowing that they’re hosed, they flail around and grab at anything they can reach: crates, walls, even each other (giving you two kills for the price of one). We also heard about another instance where an object was hurled at a group of stormtroopers, prompting one self-concerned recruit leapt heroically out of the way – and right over a ledge. The dynamic reaction of enemies and environments make every battle different and spectacular. It’s not just for show, though: the game awards style points, which are then used for upgrading powers, combos and passive power-ups, like added health and lightsaber crystals. We also learned that each level unlocks a new costume for The Secret Apprentice, which you're free to wear or switch out for an earlier outfit.
