Some good times in Rome, best fun I've had in the game so far. I wish the whole game was full of more things like that "sniper" mission.
I've had no problems on my PS3 playing the game, no worse than anyone is reporting. You really have to go into the game wanting to play a Choose Your Own Adventure not the shooting parts though.
Still a high 7 for me. But from someone who likes the game, I don't understand any review, even from an RPG outlet that praises the shooting. Any RPG outlet reviewing Alpha should have played Mass Effect 2 already, and even if not they've had plenty of time to play Mass Effect 1 which still had better combat.
The choice is what makes this game, you have to go in wanting that Heavy Rain style 'My game was way different than yours' experience and that really has to be enough for you.
There should be plenty of people out there that'd be fine with that, but it's going to have a hell of a time finding those people if you trick the shooter audience who hated Mass Effect 1 into playing this.
