UGO now has a new Fallout 3 FAQ and newshub. Pretty uninspired stuff so far, but they are only starting. An example:
Like Oblivion and the first two Fallout games, your combat success is determined by your stats. Damage and accuracy will increase as you raise appropriate skills, or depending on your SPECIAL attributes. But, even though there’s a heavy RPG system behind it, you can play Fallout 3 as you would a twitch-based shooter, with all the chance-to-hit info hidden in the background. Run into a room and start blastin’ away, if you feel up to it!
But Fallout fanatics fear not! Fallout 3 also has an optional turn-based combat system called V.A.T.S. that you can use at any time during the game. Hitting the right bumper during combat will pause all action and zoom in on your nearest target, showing you chance-to-hit percentages for every part of its body. The head, for example, is much harder to hit than the torso, but bring up your skills enough and you’ll be knocking out headshots with ease.
When in turn-based combat mode, you’ll be spending Action Points to perform different, well, actions. Firing a gun or reloading takes up a certain amount of action points, and when you run out the game will pull out of turn-based mode, forcing you to play in real-time until the points recharge. Just like F1 and F2, more agility equals more action points, so don’t be hesitant to boost that stat if you’re into planning ahead.
It’s not a turn-based mode, it’s the Vaultec Assisted Targeting System! Geez!…
But they are right on something, Agility is the stat of choice in Fallout 3.
