Mass Effect - Video Walkthrough @ IGN
IGN has a 20-minute Mass Effect video walkthrough:
Following the private demo, BioWare President Greg Zeschuk went on IGN Livewire to show off Mass Effect to the public. The demo focuses more on the combat than the RPG aspects, which saves future Mass Effect players from having a major plot point spoiled several month's before the game's release.
