Welcome to this site !
This site is about the Tomb Raider game, and specifically about building tools for viewing / modifying / editing the game.
The ultimate goal is making a level editor which would allow anyone to build a level for Tomb Raider.
I won't be able to make such an editor alone, but we are several guys working on this (see the Links), and I hope one day we will have all the necessary tools to make this possible.
My little contribution to this project is TRViewer, which is a level viewer for TR1/2/3/4. With TRViewer you can view and change all textures / meshes / moveables (a set of meshes) of a level. See the TRViewer link to get more informations about TRViewer.
