Translation: your squadmembers can die on individual main campaign missions.
According to Former BioWare Dev. How Squad selection is handled is nothing like ME1 and ME2. Some Squad Members will always be available Like Ashley or Liara.
Other Squad Members will join you for a Period of time and leave. Their was a video showing Aria and Shepard fighting Cerberus.
We should have around six Permanent Squad Members.
The load looks to be the following:
- Liara - Ashley - Garrus (If Alive) - James Vega - Tali (If Alive) - Unannounced New Human Female
- Ashley will have Armor in Mass Effect 3. It will be female version of blue Alliance armor we've shown on Kaidan. - Their will be new Alliance Uniforms that you will be able to wear on Normandy SR-2. - What you have seen so far has been Placeholder Face for Liara. Bioware has yet to show the final look for Liara.
- The Earth Trial: "It's more of an investigation, than a full trial. And it's several weeks long." - Cloak is lot more useful now. You are able to toggle it off at will which shortens the cooldown
- Big Mass Effect Announcement/info Incoming. The Media/Press already knows what the announcement/info is. However it's under embargo as of right now. The Embargo should be lifted by Next Tuesday.
