Bethesda plz plz keep this 10x damage for stealth kills! That sounds so awesome and if it's like that in the game I would seriously not know what class to play first... which is good lol. Also the fact that enemies will not autotomatically know where you are when they hear or see something is just such a nice feature. Quote:
"Stealth basically works the same as it did in Oblivion, but Bethesda has slightly altered what happens once enemies detect your presence. Now when NPCs think they see or heard something, they go into an alert state. Characters with a higher sneak skill will have more time to duck back around the corner or find sanctuary in the shadows. This new system eliminates the sudden attacks that sometimes caught players off guard in Oblivion."
The only thing I am slightly worried about is in the trailer we see a stealth kill and the other people in the tavern are completely oblivious to it even though there's a guy getting his throat slit right in front of them. That's really not how it should be in the final game imo.
