Shacknews has published their preview, along with the rest of the world. Interestingly, this preview reveals yet another tidbit of information:Sadly, groin targeting has not returned for Fallout 3. The designers decided to keep the targetable areas to body parts that would have tangible effects when targeted--shooting a leg will cause the enemy to stumble, shooting out an arm might cause it to drop its gun. "You will no longer be able to punch a rat in the groin," Howard said.Aimed shots to the groin are out.
There was also a rather odd gameplay example:Howard noted that Bethesda developer Ashley Chang can frequently be seen wearing the uniform of the sheriff while perched in a tower, taking shots at the inhabitants of Megaton. A less ruthless player might find that killing the sheriff and donning his clothes, then acting the right way towards the citizens, might actually eventually result in being recognized as the new sheriff.And again, the mini-game feature is confirmed:Hacking computers and electronics is a part of Fallout 3, and is represented by a simple code-breaking mini-game similar to the classic Mastermind.Link:
