Demo
From WikiRaider
A Demo is usually a single level, or part of a level, that should demonstrate what the game will be like.
Game Developers mostly release these demos a few weeks before the full game is released. A demo serves as promotion for the developer and the PC gamer can find out, if his/her hardware is compatible.
Here's a (partial) list of the Tomb Raider Levels, that served as demo:
Contents
Tomb Raider
Tomb Raider II
Tomb Raider III
Lost Artefact
The Last Revelation
- Library Demo (not found in the actual game)
Tomb Raider Legend
PS2 Version released in the german OPM on March 10th 2006
