•Lara's body reacts to the weather and environment - if it is hot, she will sweat. If it is raining, the water will trickle down her body. If it is muddy, dirt will cling to her and gradually wash off due to the rainfall. Her clothes will also react to changing environmental conditions. Lara interacts with environmental foliage, sweeping it away as she passes through it.
•Crystal Dynamics have introduced motion capture for the first time in a Tomb Raider game. Motion capture brings increased realism and fluidity to Lara's movements. CD have hired an olympic gymnast to provide animations for Lara.
•Lara will have high quality facial animations and lip-synch.
•TRU uses a realistic and dynamic weather system including torrential rainpour, thunderclouds and lightning. Each level will have its own weather system.
•An improved physics engine means that the whole world is reacts to Lara's presence and has memory. Lara leaves footprints in the mud. Debris and bodies will no longer vanish, providing valuable markers of where the player has been in the massive game world.
•An innovative lighting system moves beyond simple dynamic lighting to create stunning and realistic environments. A new piece of lighting technology called Spherical Harmonics is being used to make Lara appear connected with her environment; if she walks through green foliage, for example, her skin will take on a subtle green cast.
•All cutscenes are made using the in-game engine
