I don't know, I doubt the radial would have more than 8 slots if it is like an analogue driven hotkey system. But Mass Effect has a hotkey bar doesn't it? I have never played it on Console. The only difference would be presentation, PC version will more than likely just have the regular hotkey system.
Holding breath while aiming + Bullet time, I guess they made Steady worthless, I wonder if they will even have any chems in the game.
The Ghoul thing sounds retarded... Ghouls aren't Zombies, if they are gonna have that "Shooting limb off but still living" thing they should then have it for all living enemies.
