of Legend, Anniversary and Underworld. The music for Temple of Osiris was written by Will Roget II, who had originally worked on licensed video games including Star Wars: The Old Republic. Temple of Osiris was the first title in the Lara Croft subseries to have an original score, using Egyptian and Middle Eastern musical elements while creating a new main theme that could be used in future Lara Croft games. Technology The first Tomb Raider used a custom-built game engine, as other equivalent engines available to Core Design at the time were not versatile enough to realise the team's vision. The engine was designed by Paul Douglas, who handled the game's artificial intelligence (AI) and the three-dimensional (3D) graphics. The choice of a 3D game was influenced by the team's opinion that the game type was under-represented when compared to first-person shooters such as Doom. Its 3D style meant multiple elements were difficult to implement, including the AI and camera control. Another noted aspect was the multi-layered levels, as compared to equivalent 3D action-adventure games of the time which were limited to a flat-floor system. Lara's movements were hand-animated and coordinated rather than created using motion capture. The reason for this was that the team wanted uniformity in her movement, which was not possible with motion capture technology of the time. For Tomb Raider II, minor upgrades were made to the engine, with the main improvements being to the AI and smoothing out Lara's model. Tomb Raider III underwent major revisions, including rewrites to the graphics engine and improvements in the lighting and AI systems. The engine was given a major overhaul for The Last Revelation. The first five games make use of full-motion video cutscenes. For the first three games, they were primarily used as transitional periods depicting Lara moving from one level to another or one location to another. For Chronicles, fairly minor revisions were made. For The Angel of Darkness, a new engine was built from scratch, but due to being unfamiliar and unused to the technology of the PS2, the team encountered multiple problems such as needing to remove areas and characters due to polygon restrictions. Due to the deadlines imposed, the team were forced to cut corners, meaning that the game reached store shelves in a poor condition. For Legend, the staff at Crystal Dynamics created a proprietary engine from the ground up, named the
