A summary of UK X360's World mag preview from DAC :
* The tagline says: "A Safe Bet for RPG Fans"
* Hardcore mode: Stimpaks take a long time to heal, you need a Doctor's Bag to heal broken limbs, and you suffer from Dehydration so you need to carry water.
* Dynamite is one of the first weapons you come across
* Obsidian have focused much more on the story than Bethesda did with Fallout 3
* VATS now includes a special attack for every weapon
* Weapons can be modded - one of the mods involves reducing the spooling time for miniguns.
* All of your skills can be used to influence dialogue
* A "Command/Companion Wheel" gives you control over your followers - the design of this isn't finalized yet
* Nightkin are back and can cloak
* The Hoover Dam is intact and produces electricity
* Electricity seems to be one of the main things in the game
* There are 3 factions - the NCR, Caesar's Legion, and (although unconfirmed) the Brotherhood of Steel
* The Helios One solar tower controls an orbital laser platform
* You can get a portable controller for the laser platform and use it throughout the game
* Lots of "grey areas" in terms of actions and dialogue - a combined reputation and morality system means everything you do has an effect on something in one way or another.
* New Vegas will have different endings, "instead of the single, potentially anachronistic 'man/woman saves the Wasteland' finale."
* The overall theme of the game is about trying to find out who tried to kill you and why.
* New weapon - The "All-American" - a rapid fire Sniper Rifle
I don't like the sound of the portable controller laser thing, sounds like a new Fat man to me, the rest seems good.
