Work on Grand Theft Auto IV began in November 2004, almost immediately after the release of Grand Theft Auto: San Andreas.[38] According to a financial consultant for Take-Two Interactive, around 150 game developers worked on Grand Theft Auto IV.[42] The team consists of core members of the Grand Theft Auto III team, albeit larger.[43] The game uses Rockstar's own RAGE game engine, which was previously used in Rockstar Table Tennis, in combination with the Euphoria game animation engine.[2] Instead of pre-written animations, Euphoria uses procedural animation to control the way the player moves, enabling character movements to be more realistic.[44] The Euphoria engine also enables NPCs to react in a realistic way to the player's actions. In one preview, a player knocked an NPC out of a window and the character grabbed onto a ledge to stop himself from falling.[45] The game also uses middleware from Image Metrics to facilitate intricate facial expressions and ease the process of incorporating lip-synching.[46] Foliage in the game is produced through SpeedTree.[47] stone cold ouch killed insane stunts grand theft auto dieing insane deaths cool things happen
