List of things I noticed about Mass Effect 2 that were different:

-The view is much darker than the last Mass Effect.

-The crosshaires are more precise on assault rifles.

-More Biotic powers.

-They have bigger and better guns. The game featured a gun that looked like a BFG and it shooters a guided missile at opponents.

-Frame rates got an overhaul.

-The AI got a huge overhaul. They went up against new Eclipse Troopers, Eclipse Vanguards and Eclipse Commandos and Loki Mechs in the demonstration.

-Lifebars are completely different. Your shield gauge is in a stacked form instead of horizonatal.

-The battle communicatiton with squad mates is amped up. It works better when you give them commands.

-

-New news:There is a new Alien called "thing"or "Phing" or something like that. I didn't quite get what the Bioware guy was saying and he refused to state the species. Anyway, you'll be working with that guy and supposedly he's of the best assassins in the galaxy.

-New news: Shepard is going to be teaming up with mercenaries this time around to take on the new threat in the Mass Effect world.

Nice, thanks for the update.

Looks like great improvements all around. Glad to see they (perhaps) fixed several of the issues fans had with the previous game.

This game - I can not wait. I can't wait for a media pass to check it out.

12 recruitable characters in ME 2.

God I cannot wait. The game looked so awesome!

awesome this is my most anticapated game right now thanks for the update

all of it was amazing. I wish they could have showed more.

I wish they would put that demon on Xbox Live instead of making us cringe for so long.

Twelve recruitables? TWELVE!?!?!?!

Awesome.

The variety of team mates seem amazing. There also seem to be more classes. Commando is another class I noticed was in the game.
