Intended for next-generation consoles, the playable version of the game behind closed doors at the LucasArts booth was very early in development but showed some potential, with a highly destructible environment and the promise of advanced AI. (Although they all say that, don't they?)
To prove that the game was getting away from stock animated responses to scripted situations, a separate AI demo was set up, showing Indy on a rope bridge. You could shake the bridge or throw things at our helpless archaeologist and watch him adjust and try to keep his footing and stay on the bridge.
As you can guess from the working title, LucasArts doesn't expect this game to see the light of day until well into 2007.
