GameOver has put together a preview of Fallout: Brotherhood of Steel, based upon an early copy of the game they were able to get their hands on. They have some pretty good things to say about the console title, and shed some light on previously unknown details:
When you level, you don't actually get anything right away. Instead, you're simply given a certain number of Skill Points, which can be spent to increase or add to your character's abilities. With Skill Points, you can improve your ability with melee weapons or firearms, increase your hit points, raise your armor rating, acquire a helpful dog as a constant companion, or buy character-specific skills (i.e. Cyrus going berserk if critically wounded, Nadia's talent with energy weapons, or Cain being healed by radiation damage).
The overall effect is subtle; you can turn yourself into a melee tank, wielding a sledgehammer to vicious effect, or, instead, opt to turn the game into more of a shooter. Either way, you'll be able to buy or find a wide variety of weaponry with which to beat the sweet hell out of anything that gets in your way, from spiked baseball bats and pikes to automatic weapons and laser cannons.
