Tomb Raider III: Adventures of Lara Croft is an action-adventure video game developed by Core Design and published by Eidos Interactive. Tomb Raider III was built on an upgraded version of the Tomb Raider engine that was used by its predecessors. The engine offers better speed efficiency and new graphical features such as coloured lighting and triangular polygons, allowing developers to achieve greater detail and more complex geometry. The game was designed to be more in line with the puzzle-solving gameplay of the original Tomb Raider as opposed to the more shooting-oriented style of Tomb Raider II.
