You can download Alias Underground from the ABC site. The game is basically a cheaper (looking), less-sophisticated Tomb Raider interface.

Upside1: downloadable missions continue to be added, and all seem to be based off of actual scenes from the show.

Upside2: Voice acting is all done by the actual actors from the show, which means you get even more sound bytes from Marshall. Bonus!

Downside: Did I mention the poorly done graphics and simplistic interface?

Still, IMO, it’s worth it just to hear Marshall during the training episode.
