Lara Croft: Tomb Raider - Anniversary for mobile phones differs from the PC/console version in that it is not directly based on the original 1997 Tomb Raider game. Instead it is made out of content from an earlier trilogy of mobile Tomb Raider games: The Osiris Codex, Quest for Cinnabar and Elixir of Life. Essentially the game is a selection of levels from those games that have been rearranged within an overarching storyline based on the 1997 game. Some graphical changes has been made but level design and game mechanics are the same.
