• You will play as Shepard, but for how long is unknown
• There is a new species called the Drell and Thane is a new character who is an assassin and may join your party
• Planets - There will be a Krogan planet, and Illium, an Asari planet, that is like Coruscant from SW. Also there is “Omega” with is like an anti-Citadel in that itÂ’s huge and itÂ’s the bottom of the barrel whereas the Citadel is the height of civilization. Also a Cerebus mothership will act as a location of significance.
• Story - The ultimate story is still civilization fending off the Reapers, but this chapter will deal with this Cerebus corporation and itÂ’s enigmatic leader. There are human civilizations disappearing and itÂ’s up to Shepard to investigate, itÂ’s termed as a “suicide mission” which may lead to the details of the teaser.
• New vehicle that controls better than the MakoÂ…a “new” control scheme.
• Totally revamped inventory system
• Elevator system revamped where you will get the sense of scope of where youÂ’re at and where youÂ’re traveling.
• No more texture pop in.
• Secondary races like Volus and Elcor are much more mobile, giving more depth and makes things more interesting.
• Choices are more meaningful and there is a real risk that major support characters (i.e. anyone not Shepard) can and will die.
• Also on the story, theyÂ’re super-hyping the ending, saying that itÂ’s much more grand meaningful in ME2.
• More weapons, more species, more/new team members.
• returning team members, locations, weapons.

• The devs and the coming expo - the Mass Effect 2 pre-E3 video
• BioWare promises big Mass Effect 2 stuff at E3, Shepard not dead
