Grand Theft Auto IV/Features: Difference between revisions

GTA IV is powered by [[RAGE]] (Rockstar Advanced Game Engine), with a Euphoria, Endorphin physics engine created by NaturalMotion.  The core technology is the Dynamic Motion Synthesis (DMS) system.  This new physics engine gives characters a "central nervous system" allowing more natural, unscripted movements.  It also adds weight to each characters footsteps and causes them to transition depending on their surroundings.  This is apparent when characters walk up and down stairs; instead of moving like the stairs are a flat surface, the stance of the character changes depending on if they are moving up or down.  Characters react realistically to being hit with gunfire, cars, and melee weapons or fists.  Characters will be able to hang on to helicopters and trucks, which will swing them around as the vehicle moves.  Falling/thrown characters will react as in real life.  They won't simply be limp, lifeless ragdolls.  Nor will they use a canned "super hero" animation like before.  Players are also able to push people out of the way, rather than "floating" past them as in older games.
