1) There will be partial voice acting for things like CO Powers and certain key lines in the Campaign. Some names listed are Veronica Tyler as Andy, Aaron Hanson as Max, Matthew Mercer as Grit, and Laura Bailey as Colin.
2) In War Room, you’ll have the option to play by AW1 or AW2 rules. AW1 rules disable Super CO Powers and Neotanks. It’s unclear if AW2 COs will have an “AW1” version in Vs Mode.
3) Online Multiplayer will be present, but has yet to tested. Most of the development has gone to fixing bugs for Singleplayer and Local Co-Op.
4) You will be able to create and share custom maps, but will not be able to play them online.
5) The topic of heavy debate, the game is expected to receive some light balance changes. At the very least, Max is nerfed down to his AW2 D2D, and Eagle will work kinda like he does in DS; Lightning Drive will let him command his non-Soldier units again but nerf them, and Lightning Strike will let him command his non-Soldier units and buff his Air Units.
6) There will be three difficulties: Casual, Classic, and Challenging. The AI has also been updated such that it gets more intelligent as the campaigns go on. This may lead to Challenging being even harder than the Advanced Campaign.
7) The CO themes have been remastered. In addition, whenever a CO activates a CO Power, a more upbeat, aggressive version of their theme will play for the turn. The video was unclear if there is a third theme for Super CO Powers.
8) Clone Andy will be his own character. Mechanically he will be the same, but he’ll have blue eyes and Orange Star troops with Blue Skin. He has actual character and he has a unique CO Power animation. You can play him in Vs Mode.
9) Many COs have been redesigned from the Original Trilogy. Sami has been changed to be more like a Commando since launched, Sonja will have glasses and be pretty cocky, Flak will be absurdly muscular, Lash will be a “sexy goth”, Adder will be much scarier, and Sturm will be kinda like AW2 meets Darth Vader. Also Sturm blows smoke out of his mask when he uses his CO Power.
