Mass Effect 3 Extended Walkthrough

Spike TV has put online on GameTrailers a juicy extended walkthrough of Mass Effect 3 of roughly 11 minutes divided in two parts (Part I, Part II), where BioWare's Casey Hudson showcases a sizable chunk of gameplay, including a lot of combat and cutscenes and a little dialogue.

The sections showed include a mission on the Salarian homeworld to rescue a fertile Krogan female and the beginning on the game during the Earth's Reaper assault. Casey Hudson talks about the improvements done to the combat (including "visceral melee attacks"), the way they've better integrated action and cutscenes, briefly mentions the RPG elements after being quizzed by the host, and discusses how Mass Effect 3 is going to have the "biggest" beginning in the series. In case you're interested in the game this is a must watch.
